Explanation of the system configuration example
In this system configuration example, this product is powered by a single power supply from an AC adapter.
As video sources, two cameras are connected to the HDMI INPUT connectors of this product. This makes it possible to switch and stream the video captured by each camera, or to stream a video that composites the content captured by both cameras, such as picture-in-picture (PinP). In addition, a display is connected to the HDMI OUTPUT connector so that the actual content being streamed can be monitored.
As additional audio sources, analog audio signals from a music player and a microphone are connected to the LINE and MIC connectors of this product, respectively. This allows the microphone to capture the talk of the streamer while also adding the BGM played by the music player to the streamed audio. For BGM playback, instead of an external music player, you can also use the BGM player function built into this product (→BGM player). These audio sources, including the two HDMI audio inputs, can be mixed at any desired level.
For the network connection, an Ethernet (wired LAN) connection is used, and the Ethernet port of this product is connected to a separately prepared Gigabit Ethernet switch. Connectivity from this product to the internet is ensured through a router that serves as the default gateway. In addition, a laptop computer running a web browser is also connected to the same network in order to operate LiveShell Studio.
System configuration variations
In addition to the typical configuration example described in the previous section, the following configurations are also possible.
Use a dual power supply to make the power redundant
Use a PC as a video source instead of a camera
Use only a single video input and stream without using the switcher or compositing functions
Use the product without connecting a display for monitoring
Use the product without inputting analog audio
Connect to the network using a wireless LAN instead of Ethernet
For specific connection and setup methods, please refer to the following chapters.

Displays whether the power source, such as an AC adapter or power bank, is connected to the MAIN or SUB port. This will be grayed out if a connection cannot be detected.
Media connection status
Displays the mount status and remaining capacity of the SD card/USB drive. This will be grayed out if a connection cannot be detected.
System video format
Displays the system video format currently set on the main unit.
Live viewing of the input video (Preview display area)
The left half of the LiveShell Studio application screen is the “Preview display area”, where you can display thumbnails of the video received on the two HDMI inputs. In the preview area, you can also visually perform video switching, video composition settings, and more.
When you set the “INPUT Preview” switch to “ON”, thumbnails of the actual input video are displayed as live viewing of the input video. When set to “OFF”, live viewing stops, and the still images “A” and “B” are used as substitute images to represent the selected video.
Live viewing of the program output (Program display area)
The right half of the LiveShell Studio application screen is the “Program display area”, where you can display the composited program output video in the “PGM OUT” area. In this area, you can also perform operations such as changing the network streaming destination settings and starting or stopping streaming.
When you set the “PGM OUT Preview” switch to “ON”, live viewing of the program output is displayed. When set to “OFF”, nothing is displayed. In addition, using the “Mode” switch, you can select the rendering method for live viewing from either “Simple” or “Full”.
When “Mode” is “Simple”, a simulated composite video is displayed using the live viewing video of the input. When the “INPUT Preview” switch is “OFF” and live viewing of the input video is stopped, the substitute images “A” and “B” are used for the composition.
When “Mode” is “Full”, the same stream as the one being streamed is acquired and played back. In this mode, you can also monitor the audio, but audio playback does not start automatically. You can check the audio by unmuting it in the browser (the method for unmuting varies by browser, but can generally be done by right-clicking to display the controls).
Limitations of live viewing
The video displayed as live view has the following limitations.
If signal reception from HDMI is interrupted, the thumbnail on the preview screen continues to display the last frame shown. Also, if the HDMI format recognition does not match the video reception state, the thumbnail may not be displayed correctly. This does not apply when “INPUT Preview” is OFF.
When “Full” is selected as the live viewing mode for the program output, the video and audio are generated by playing back the same stream as the one being streamed, so there is a delay compared to the input video thumbnails. There is also a discrepancy with the movement of the audio level meters.
When “Simple” is selected as the live viewing mode for the program output, the video uses the thumbnail images used on the preview screen and uses a simulated composite result. This simulated video has the following limitations.
It does not exactly match the actual program output.
Video effects such as Mix and wipe are not reproduced.
Chroma key is not reproduced.
No audio is output.
On Safari and iOS browsers, live viewing of the program output in “Full” mode is not available.
The default state of live viewing for both the input video and the program output is “ON”. However, when you connect to LiveShell Studio via LiveShell Remote, the default state is “OFF”.
For the purpose of monitoring the program output, you can also use the monitor output (→Connecting a video monitor output) or the RTSP server function.

Definitions of terms related to video manipulation
Video input names
In the user interface of this product, the two video signal inputs are labeled “Input A” and “Input B”.
Input A
Input A corresponds to the video input to the HDMI INPUT 1 terminal.
Input B
Input B corresponds to the video input to the HDMI INPUT 2 terminal.
Program output
This is the final output video after switching and compositing, and is the video that is actually streamed.
Switching (video switching)
Switching is a mode in which only one of the videos, either Input A or Input B, is selected for program output. Switching can be operated with either the video select button on the main unit or LiveShell Studio.
Switching operation by the unit
Using the video select button on the main unit of this product, you can switch video by operating the unit alone. When “A” of the video select button is pressed, the program output switches to the video of Input A, and when “B” is pressed, the program output switches to the video of Input B. When switching is performed using the video select button, the video effect at the time of switching is a MIX with a transition time of 1 second.
Even when Picture-in-Picture, Split screen, or Chroma Key compositing is applied by operating LiveShell Studio, pressing the video select button on the main unit cancels the compositing and the selected input becomes the program output.
Lighting status of the video select buttons
The video select buttons indicate how the video inputs are selected by their lighting status.
When Input A is selected as the program output, video select button A lights up red, and when Input B is selected as the program output, video select button B lights up red. The other button lights up green. However, when both inputs are being used through video compositing (→Video compositing), the buttons light up as follows.
In Split screen, both video select button A and video select button B light up red.
In Picture-in-Picture or Chroma Key, the video select button for the input used as the main screen lights up red, and the video select button for the input used as the sub-screen lights up yellow.
During a switching transition by AUTO, both video select button A and video select button B flash red.
Switching operation using LiveShell Studio
To perform switching with LiveShell Studio, proceed as follows.
Select “Switching” from the slider at the top of the preview screen.
Select the desired switching destination on the preview screen (Input A or Input B). When selected, the relevant screen is displayed as “Selecting”. The following is an example of preparing to switch to Input B when Input A is being used as the program output.
Pressing the AUTO or CUT button with the switching destination selected switches the program video output to the currently selected input. The differences between AUTO and CUT are as follows.
With AUTO, the video effect specified by TYPE is applied over the time set by RATE (→Selecting the video effect for switching).
With CUT, the video is switched instantly without applying any effect.
Selecting the video effect for switching
Video effects can be applied for smooth video switching. The effect to be applied can be selected from the TYPE pull-down menu. There are two types of video effects: Mix and Wipe.
Mix
The two videos are composited by fading, transitioning smoothly between them.
Wipe
The screen is split and the dividing line is moved to transition between the two videos. Depending on the direction in which the dividing line moves, you can choose from the following four types.
Wipe (from left to right)
Wipe (from right to left)
Wipe (from top to bottom)
Wipe (from bottom to top)
Specifying the transition time of the video effect
The transition time for Mix and Wipe can be specified by entering the time in seconds in the “RATE” field. The default value is 1.0 second.
Video compositing
With this product, the two video inputs, Input A and Input B, can be composited into the program output. To use the video compositing function, first select “Composition” from the slider at the top of the preview screen, then select the compositing method to apply from “PinP”, “Split screen”, or “Chroma Key” on the left side of the preview screen.
Using Picture-in-Picture (PinP)
Picture-in-Picture (PinP) is a compositing method that overlays a different, scaled-down sub-screen on top of the input that serves as the main screen. The position and size of the sub-screen can be changed freely.
To use this compositing method, operate as follows.

Select “Composition” from the tabs at the bottom of the preview screen.
From the “Source selection” pull-down menus under “PinP” in the Composition tab, select the input to use as the main screen and the input to use as the sub-screen. The main screen and sub-screen can also be selected from the pull-down menus displayed within the preview screen.
Use the “Size” slider under “PinP” in the Composition tab to select the size of the sub-screen. It can be adjusted as a reduction ratio relative to the full screen.
Under “Position” of “PinP” in the Composition tab, press to select the position at which to composite the sub-screen. After selecting, you can fine-tune the compositing position by operating the vertical and horizontal sliders.
Pressing the AUTO or CUT button in the preview screen switches the program video output to the composited video you have set.
Using Split screen
Split screen is a compositing method in which a portion is cut from the two video inputs and placed side by side on the left and right. You can select one of the following ways to cut out a portion.
Center split
In Center split, the screen is divided at the center and the two videos are placed on the left and right of the dividing line. You can select one of two ways to crop the video: “Left/right crop” and “Center crop”.
Center split (Left/right crop)
In Left/right crop, the left half and right half of the original video are each cut out and used as the compositing sources.
Center split (Center crop)
In Center crop, the central portion of the original video is cut out and used as the compositing source.
Seminar mode
Seminar mode is a split suited for placing the slides and the presenter’s video side by side within a 16:9 screen range. Depending on the combination of which side of the screen the slides are placed on and the aspect ratio, you can select a compositing method from the following four.
With the 4:3 options, a 4:3-sized slide and a center-cropped presenter video are composited within the 16:9 screen range. With the 16:9 options, a slightly reduced 16:9-sized slide and a center-cropped presenter video are composited within the 16:9 screen range. In each case, you can choose whether to place the slides on the right or left side of the screen.
Seminar mode (4:3 left)
A 4:3-sized slide is composited on the left and a center-cropped presenter video on the right.
Seminar mode (4:3 right side)
Composites a 4:3-size slide on the right side and a center-cropped video of the presenter on the left side.
Seminar mode (16:9 left side)
Composites a slightly reduced 16:9-size slide on the left side and a center-cropped video of the presenter on the right side.
Seminar mode (16:9 right side)
Composites a slightly reduced 16:9-size slide on the right side and a center-cropped video of the presenter on the left side.
To use this compositing method, operate as follows.
Select “Split” from the left side of the preview screen.
On the preview screen, select the input to use as the left half of the video and the input to use as the right half of the video.
Select “Composition” from the tab at the bottom of the preview screen. Select “Split Type” from “Split” on this tab.
Pressing the AUTO or CUT button in the preview screen switches the program video output to the composited video you have set.
Using chroma key
Select “Chroma Key” from the left side of the preview screen.
Select “Chroma Key” from the tab at the bottom of the preview screen.
From the “Source Selection” pull-down menu of “Chroma Key” in the Chroma Key tab, select the input to use as the background and the input to use as the key. You can also select the background and the key from the pull-down menus displayed in the preview screen.
Use the color picker or the eyedropper tool to select the key color to be made transparent.
If you select the eyedropper tool, the “Key Color Selection” dialog appears. From the source selection pull-down menu at the bottom left, select the input to use as the key. After selecting the key color to be made transparent, press “OK”.
Use the “Error Range” slider or numerical input to specify the range of similar colors to be recognized as the key color.
Pressing the “AUTO” or “CUT” button in the preview screen switches the program video output to the composited video you have set.
Tips for selecting the key color gamut
The chroma key function of this product can be used effectively for a color gamut where one of the three primary colors of light (red/blue/green) is predominant and the brightness is generally uniform. Composite colors (e.g., yellow) cannot be clipped well.
If the brightness of the color gamut used as the key is low, good cropping will not be possible.
To select the key color, refer to the thumbnail image and select a color that is as bright as possible within the color gamut to be used as the key color.
Keep the error range at roughly 50% or less. If it exceeds 50%, unintended colors may also be recognized as the key.
The chroma key composition result is not displayed on the preview screen. Adjust it while viewing the HDMI OUT program output or the streaming video.
Video effects when compositing video
When compositing video, transition video effects can be applied only to the following combinations. No video effect is applied when switching between different composition modes.
Transition between no composite and PinP
The Mix effect can be applied only when transitioning between the same input and the input used as the main screen for PinP. All other effects will be disabled even if selected.
Transition between no composite and split
Only Wipe can be used to transition between no composite and split. Also, regardless of the wipe direction specified, the wipe will be in the direction that is actually applicable according to the input to which it is being switched.
Transition between no composite and chroma key
The Mix effect can be applied only when transitioning between the same input and the input used as the background for chroma key. All other effects will be disabled even if selected.
Using telops
The telop feature lets you composite any still image and text onto the program output video. You can use it to display a message to viewers or to show a logo on the program output. The telop feature described in this chapter is available with firmware revision v1.5.0 or later.
Basics of creating a telop
A telop on this product consists of multiple “layers”, and is expressed as the composite of these stacked layers. There are three types of layers: “image layers”, “text layers” and “clock layers”. You can create the telop you want by first creating an empty telop and then adding the raster images and text strings needed as its content as image layers, text layers and clock layers respectively.
When using an image layer, you must create the still image to be used as the layer in advance with image editing software or the like, and upload the image to this product’s memory on LiveShell Studio. Text layers and clock layers can be entered and edited on LiveShell Studio.
Creating a new caption
To create a new caption, follow these steps.
To create a telop that consists of a single image layer only, you can also create a new telop by dragging and dropping a PNG image file that meets the conditions for an image layer onto the telop list. When you do this, the file name of the uploaded image file is used as the telop name.
First, select the “Caption” tab and click the “New” button. If you have already saved telops, a list of their thumbnails is displayed in this area.
Clicking the “New” button at the bottom opens the telop editing screen. At this point the telop has no layers making up its content and is uniformly transparent.
You can give a telop any name you like. The name of a newly created telop is “New Telop”. You can change the name by clicking the “Edit” button next to it.
Adding a Layer
To add a new layer to a telop, click the “+” button at the bottom of the layer list on the telop editing screen. A submenu appears for choosing “Image” or “Text”; select “Image” to add an image layer, or “Text” to add a text layer.
Adding an image layer
When you select “Image” in “Adding a layer”, you are prompted to upload an image file. Select the image file you prepared in advance on your operating computer or the like and upload it. This image must meet the following conditions.
The file format must be a PNG image.
Interlaced PNG is also supported (v1.5.0 or later).
It is preferable that the image resolution be the same as the system video format (→System video format).
For example, if the system video format is set to 1920x1080 60p, it is recommended an image size of 1920x1080 dots.If the system video format is set to 1280x720 60p, we recommend an image size of 1280x720.
If the image resolution differs from the system resolution, it will be adjusted to the same size as the system resolution, ignoring the aspect ratio, and then composited.
The file size must be 4 MB or less.
The example below shows the state immediately after uploading an image layer depicting a logo.
Adding a text layer
When you select “Text” in “Adding a layer”, the text telop editing screen is displayed. On this screen, in addition to the text content to be displayed as a telop, you can edit instructions such as the size, color and on-screen placement of the text.
To check how the edited text and its composite with other layers will look, click the preview screen. The example below shows the result of compositing the text string “Live!” in addition to the image layer for the logo, displayed as a preview.
Note that the preview is not updated automatically.
Text editing
Enter the characters to display as a telop in the text box labeled “Input text…”.
Text font and size
You can select the text font from the “Font” pull-down. The text size can be specified in pixels. The default size is 100 px. Also, to make the text bold, click “B”; to make it italic, click “I”.
Text alignment, horizontal
You can select the horizontal alignment of the text from “Left,” “Center,” or “Right.” This selection determines which part of the text will be used as the basis for positioning when you “Specify text position” as explained in the next section. The criteria for positioning are as follows:
Left edge of text if left-justified
Center of text if centered
Right edge of text if right-justified
The horizontal alignment of the text can be set manually, and it is also set automatically when you position the text using the “position box”.
Text positioning
You can position the text within the text area using the positioning box, fader, or by entering the X and Y coordinates directly.
Using the position box, you can place the text in one click at one of “Center”, “Top center”, “Bottom center”, “Top left”, “Bottom left”, “Top right” or “Bottom right” within the telop area. The horizontal alignment of the text is also set automatically according to this placement. When placed at “Center”, “Top center” or “Bottom center”, the horizontal alignment is set to “Center” and the text is centered within the telop area. When placed at “Bottom left” or “Top left”, the horizontal alignment is set to “Left” and the left edge of the text is aligned to the left edge of the telop area. Similarly, when placed at “Bottom right” or “Top right”, the horizontal alignment is set to “Right” and the right edge of the text is aligned to the right edge of the telop area.
You can fine-tune the text position horizontally by moving the slider below the position box, and vertically by moving the slider to the right of the position box. You can also specify the position by entering immediate values for the X and Y coordinates. The unit of the values is percent, given as a ratio to the horizontal and vertical resolution with the upper-left of the screen as the origin.
Text color and transparency
You can specify the color of the text body, background, and border separately. You can also specify the transparency of each element. Areas without any of these elements will be transparent.
The color can be specified by selection with the color picker, by specifying it in #RRGGBBAA hexadecimal format, or by entering immediate values for red, green, blue and transparency. When entering colors as immediate values, 0 is the minimum and 255 is the maximum. For transparency, 0 is fully transparent and 255 is fully opaque. Due to rounding, the transparency value may deviate from the set value by 1, but this is not abnormal.
Adding a clock layer
To add a clock layer, follow the steps below.
When you select “Clock” in “Adding a layer” described in the previous section, the clock telop editing screen is displayed.
On this screen, in addition to the content to be displayed as the clock, you can edit instructions such as the size, color and on-screen placement of the text.
The text editing method is the same as for the text layer. The editing method differs depending on each item. Refer to the individual procedures below for each.
The preview is not updated automatically. To check it, click “Preview” to refresh.
To edit the layer name, press “Edit”.
Enter any layer name and press “Save”.
When all editing is complete, click “Save”.
Once saving is complete, the “Edit Caption” dialog will close automatically.
Clock display format
You can also insert specifiers using the buttons below the text box. In addition, you can select the time zone from the pull-down menu to its right. The default is the time zone set in the unit settings (→Time zone setting).

The BGM player is operated from the BGM tab in LiveShell Studio. The BGM tab displays the file name of the currently playing track, its position in the playlist (current track number / total number of tracks), and the following operation buttons.
Play / Pause: Each press toggles between the playing and paused states.
Stop: Stops playback and returns to the beginning of the track.
Next track / Previous track: Moves to the next or previous track in the playlist. When operated at the beginning or end of the playlist, it wraps around to the last or first track, respectively.
Switch loop mode: Described later.

Switching loop mode
The BGM player has the following two loop modes. Each press of the loop mode toggle button on the BGM tab switches between them.
Loop all tracks: Plays all tracks in the playlist in order, and when the end is reached, returns to the first track. This mode is the factory default setting.
Loop current track: Repeatedly plays only the currently playing track.
The state with Loop current track selected (the loop mode toggle button is highlighted in blue)
Input to the mixer
The audio played back by the BGM player is treated as the “BGM” source of the audio mixer. Just like other sources, you can perform operations such as level adjustment, mute, channel setting, balance (PAN), and delay correction. For details, refer to How to operate the audio mixer.
Behavior when inserting or removing an SD memory card or USB memory device
If you remove the medium on which the currently playing track is stored during playback, the playlist is automatically rescanned. If tracks remain on the other medium, playback switches to the next track from there; if no tracks remain on either medium, playback stops. If you insert or remove the medium that does not contain the currently playing track, playback continues.
Insertion or removal while stopped or paused is not automatically reflected in the playlist. To reflect the result of insertion or removal in the playlist, perform a playback operation. This also applies when you reinsert a medium you removed.
Behavior when no music files are found
If there are no audio files in the “bgm” directory on either the SD memory card or the USB memory device, playback will not start even if you perform a playback operation, because the playlist is empty, and a message indicating this is displayed on the BGM tab. Check that the audio files are correctly placed on the SD memory card or USB memory device.
The BGM tab when no music files are found
Audio encoder
The output of the audio mixer is internally connected to an AAC-LC encoder. The AAC-LC encoder compresses the PCM audio signal and converts it into a code suitable for network streaming. The following settings can be adjusted for the audio encoder.
Audio bitrate setting
Unit menu / MAIN MENU →Encoder →Audio Bitrate
LiveShell Studio / Main screen →Audio tab →Bitrate
Factory default / 128 kbps
This is the audio bitrate setting output by the AAC-LC encoder. Set it to a rate appropriate for the streaming target. The sampling rate is fixed at 48 kHz and cannot be set.
The configurable range is as follows.
48 to 256 kbps
Output audio delay correction setting
Unit menu / MAIN MENU →Encoder →Audio Delay
LiveShell Studio / Main screen →Audio tab →Delay compensation
Factory default / 0 ms
This value corrects the discrepancy between video and audio, and the correction amount can be set in milliseconds. Setting a negative value makes the audio lead relative to the standard timing, and setting a positive value makes the video lead relative to the standard timing.
The configurable range is as follows.
-300 to 300 ms
Streaming target settings
On this product, by configuring streaming targets, you can transmit the encoded video and audio to an IP network and record them on storage media. Streaming target settings can be configured in LiveShell Studio. They cannot be configured using the main unit.
Overview of streaming target settings
A streaming target is the destination to which the video and audio stream generated by this product’s encoder is sent, and can be broadly divided into two types: network streaming and recording.
This product can send the same stream to up to three streaming targets simultaneously. Therefore, you can have up to three streaming target settings enabled at any one time. On the other hand, there is no limit to the total number of streaming target settings that can be saved on this product. For example, if there are seven streaming target settings saved on this product as shown in the figure below, you can enable any three of the seven as the streaming targets actually used. An enabled streaming target is specifically called a “channel”.
Streaming Targets Targets selected as Channels

Stream Target 2) RTSP Server +---------> [ Channel 2 ]
Stream Target 3) LiveExample | +-----> [ Channel 3 ]
Stream Target 4) Recording ------+ |
Stream Target 5) 5555-Video |
Stream Target 6) UDP |
Stream Target 7) test-live ------------+
Protocols available for network streaming
The application protocols that can be used for network streaming are as follows.
RTMP and RTMPS
These are protocols used to send video and audio to major live streaming platforms. Whereas RTMP sends the stream in plain text, RTMPS encrypts it using Transport Layer Security. Some platforms specify the use of RTMPS.
In general, to stream via RTMP or RTMPS, you must issue an account on the live streaming platform and obtain an RTMP URL and a stream key. In addition, the recommended settings for the encoder and other components vary depending on the destination platform, so check these as well before configuring this device.
RTSP Server Mode
RTSP allows this product to act as a server and distribute video and audio to connected clients.It is a protocol suitable for use on local networks, such as for viewing program output confirmation or for distribution within a facility.
MPEG2-TS over UDP
MPEG2-TS over UDP is a mode in which video and audio multiplexed as an MPEG2 Transport Stream are sent without any procedures as a UDP datagram payload. This protocol is suitable for transmitting video to video decoders that can receive this protocol.
Recording live streaming
You can also set “Recording” as one of the targets. In this case, the stream is recorded to the storage media attached to this product in MP4 container or MPEG2-TS format. The media that can be used as the recording target are as follows:
Note that if you select MP4 as the recording container, recorded data may be corrupted if the product loses power during recording or if the recording termination process is not completed properly.
SD card
The recording target is the SD card inserted into the SD card slot on the main unit. The SD cards that can be used are limited to SD, SDHC, and SDXC cards formatted in FAT32 or exFAT format.
USB flash drive
The recording target is the USB drive connected to the USB port on the main unit. The USB drives that can be used are limited to mass storage devices formatted in FAT32 or exFAT format.
Basic operation of target settings
To add a target, follow the steps below.
Click the gear icon at the top of the program output screen.
In the factory default state, as setting examples, “RTSP Server” is pre-configured on Channel 2 and “SD Recording” is pre-configured on Channel 3. Channel 1 is unconfigured. This procedure is described on the assumption that a new setting is applied to Channel 1, but it is acceptable to rewrite Channel 2 or Channel 3.
On the settings screen that appears, click the “Change” button for the channel to which you want to apply the settings. In this example, Channel 1 is selected.
Click “+ New target”.
Enter the setting values on the screen that appears, then click “Save”.
The setting values to be entered vary depending on the target type setting. Refer to the individual procedures below for each.
For RTMP clients RTMP clients
For RTSP servers RTSP server setting
For recording Live streaming recording destination setting

Convenient operating methods
Memory function
The Memory function is a mechanism for saving settings such as the switcher state, audio mixer adjustments, and whether a text overlay is applied as a set, then recalling the saved preset with a simple operation to apply those settings. Using the Memory function, you can perform operations such as the following:
Set up switching and transitions for each scene in advance, and apply them as the program progresses.
Prepare a text overlay to apply for each scene, and apply it as the program progresses.
Change the audio mixer level only while a performer is speaking, then return it to its original level.
Prepare a cover image and overlay it when a problem occurs.
Creating a memory setting
To use the Memory function, you must first create a memory setting and edit and save the preset contents. This can be done on LiveShell Studio. To create a new memory setting, perform the following steps.
First, select the “Memory” tab.
In the factory default state, three memory settings, “Default”, “PiP”, and “Seminar”, are pre-registered as setting examples. These settings can also be re-edited or deleted (in which case they cannot be restored to their initial state unless you perform a factory reset).
Clicking the “Create New” button at the bottom displays the memory edit screen. In its initial state, its content is set to “do nothing”.
You can give a memory setting any name you like. The name of a newly created memory is “New Memory”. However, characters other than ASCII characters (such as letters and numbers) are not displayed correctly on the main unit screen. We recommend using only ASCII characters for the name.
Memory settings can be recalled using LiveShell Studio or the buttons on the main unit, as well as using external devices such as the separately sold LiveShell ControlPad or a USB keyboard.
Tip
Customizing the key assignments lets you recall memory settings more conveniently. →Key Assignment
Selecting the items to set
When editing a memory setting, you can create a preset with the desired content by using the checkboxes to select the target items that will actually take effect when the memory setting is recalled, and setting their specific values. The main items that can be selected as targets are as follows:
Composition and transition
Audio settings
Text overlay
If you select multiple items, those settings are updated simultaneously when the memory setting is recalled. Therefore, you can create presets that, for example, “switch the video source and adjust the audio mixer gain at once”, or “apply video composition and a text overlay at once”. For items not selected as targets, their state is not updated, and the state immediately before the memory setting was recalled is carried over unchanged after the recall.
The settings for “Composition and transition” and “Text overlay” are not displayed when their checkboxes are off. The display when both are turned on is shown below (depending on the screen size, scrolling may be required).
Composition and transition settings
If you want to update the video switching or composition state when the memory setting is recalled, turn on the “Composition and transition” checkbox and set the state after switching and the video effect to apply at the time of switching. This way, the specified transition is performed when the preset is applied.
The switching state can be selected from “No composition”, “PinP”, “Split”, or “Chroma Key”. For details on each setting, refer to the following.
Also, set the video effect to apply at the time of switching using “Transition Type” and “Transition Time”.
Audio settings
If you want to update the analog input gain when the memory setting is recalled, turn on the “Analog input” checkbox and set the analog audio input gain and the analog audio input mute state.
→Analog audio input gain adjustment
If you want to update the audio mixer gain and other values when the memory setting is recalled, turn on the checkbox for the channels whose values you want to update among the audio mixer channels “ANALOG”, “HDMI1”, “HDMI2”, “USB IN”, “MASTER”, and “USB OUT”, and set the gain and mute state. For the ANALOG input you can also set whether AGC is enabled, and for the HDMI inputs you can set whether AFV is enabled.
Text overlay settings
To update the text overlay application state when the memory setting is recalled, turn on the “Text overlay” checkbox and select the text overlay to apply from the list. The text overlay to be used must be created in advance.
To leave the text overlay unapplied when the memory is recalled, select “OFF”.
Re-editing a memory setting
You can re-edit a memory setting by clicking the “Edit” icon within its icon in the memory settings list. During re-editing, you can change the preset content.
Deleting a memory setting
You can delete a memory setting by clicking the “Trash” icon within its icon in the memory settings list. Once deleted, a memory setting cannot be restored.
Duplicating a memory setting
Clicking the “Duplicate” button within a memory setting’s icon in the memory settings list lets you create a new memory setting that duplicates that memory setting. The duplicated memory setting can be re-edited, and this editing does not affect the original memory setting.
Recalling a memory setting
To recall a created memory setting and apply its preset content, perform the following steps.
Operation in LiveShell Studio
First, select the “Memory” tab.
Select the one you want to recall from the icons in the memory settings list, and click the “Apply” button.
If you want to recall memory settings quickly, turn on the “Apply without confirmation” checkbox. In this case, simply clicking a memory setting’s icon recalls and applies that memory setting, and clicking the “Apply” button is no longer required.
Operation using buttons on the main unit
Pressing the MEMORY button on the main unit switches the display to memory mode, allowing you to recall the saved memory settings. To exit memory mode and return to the main menu, press the B button or the power button.
From the list of saved memory settings, use the control dial to select the memory setting you want to recall.
Pressing the control dial while a memory setting is selected recalls and applies that memory setting.
In memory mode, selecting the audio mixer icon takes you to the audio mixer settings screen. To return from the audio mixer to the memory recall screen, press the B button.
Operation using the ControlPad
Using Key Assignment, you can recall memory settings by pressing the buttons on the separately sold ControlPad. In the factory default settings, pressing button 1 recalls the “Default” memory setting, button 2 recalls “PiP”, and button 3 recalls “Seminar”.
Operation using a USB keyboard, etc.
Using Key Assignment, you can recall memory settings by key operations on a commercially available USB keyboard, etc.
Tip
When you recall a memory by operating an input device such as the ControlPad or a USB keyboard, which memory setting was selected is also displayed on the main unit screen. Use this as an operation confirmation display.
Startup memory setting
Configuring the startup memory lets you automatically apply a specific memory when this product starts up.
To set up a name, follow the steps below.
This operation can be performed from LiveShell Studio. It cannot be set on the unit button operation.
Press “Startup memory” displayed within the “Memory” tab.
The “Set startup memory” dialog is displayed. Select the memory item to recall at unit startup from the pull-down menu.
Press “Save”.
Key Assignment
The key assignment settings are a function for customizing how this product is operated to suit the conditions of the site where it is used and your preferences. By configuring the key assignments, you can operate this product using the separately sold LiveShell ControlPad (hereafter referred to as the “Control Pad”) or a USB keyboard. In addition, by customizing the functions assigned to the buttons and the control dial on the main unit, you can assign your own functions that differ from the standard ones.
The following are examples of operability that can be achieved using the key assignment settings.
Recall a memory using the “A” or “B” button on the main unit to control the video composition state.
Recall a memory using the “A” or “B” button on the main unit to insert a text overlay as a cover image.
Turn the control dial while holding down the “A” button on the main unit to adjust the audio mixer gain.
Recall memory settings using the Control Pad or a USB keyboard.
Adjust the audio mixer gain using the dial on the Control Pad.
How to configure in LiveShell Studio
The key assignment settings can be configured from LiveShell Studio. In LiveShell Studio, click “Settings” and select the “Key assignment settings” tab.
The list on the left side of the screen displays the configured key assignment settings. In the factory default state, the key assignment settings “Pad 1”, “Pad 2”, “Pad 3”, “Pad dial counterclockwise”, “Pad dial clockwise”, and “Pad dial press” are registered as initial settings. These are the settings that correspond to the separately sold Control Pad. These initial settings can also be re-edited or deleted. However, restoring the initial settings requires a factory reset.
The concept of key assignment settings
A key assignment setting is defined by first specifying a “key trigger” and then selecting an “action” for it.
Key trigger
A key trigger is the definition of an operation performed by the operator, such as pressing a button on the main unit, pressing a key on the keyboard, or turning the dial. When an operation matching the conditions defined as a key trigger is actually performed, the key trigger fires and the “action” defined for that key trigger is executed immediately.
Key triggers can be defined separately for operations on a USB keyboard, operations on the Control Pad, and operations using the buttons on the main unit. As a firing condition, you can specify a single key press or a turn of the dial, and you can also make a simultaneous key press the condition. In addition, you can add a long press as a condition. For example, you can define a key trigger that fires when the “A” and “B” buttons on the main unit are pressed at the same time, or a key trigger that fires when “A” is pressed while “B” is long-pressed at the same time.
Action
An action is the definition of the behavior performed in response to a key trigger. In addition to Recalling a memory setting, an action can specify primitive behaviors such as changing the audio mixer gain, switching inputs, and starting or stopping streaming. It can also be assigned as a key equivalent to a button for operating the main unit menu. If you want to perform a composite behavior in a single action, you can achieve this by first defining a memory setting and specifying its recall as the action.
Creating a new key assignment setting
Click the “+” at the bottom of the key assignment settings list to create a new key assignment setting. In a key assignment setting, you first select the input device that the key trigger applies to from “USB Keyboard”, “Control Pad”, and “Main Unit Buttons”. Depending on your selection, a different diagram is displayed for each device.
Key assignment settings for a USB keyboard
This screen lets you configure key assignment settings for operating this product with a commercially available USB keyboard connected to it. As the keyboard diagram shown for setting key triggers, you can choose between the Japanese keyboard and English keyboard key maps.
To set a key trigger, click the name of the key you want to use as the trigger condition on the keyboard diagram. The specified condition appears in the blank field below the device. If only one key is specified, the key trigger fires on a simple press of that key alone. If you then click another key while in that state, the key trigger fires when two or more keys are pressed simultaneously. You can add up to six keys to a simultaneous-press condition in the settings, but the number of simultaneously pressed keys that can actually be recognized is limited depending on the keyboard and key types used.
A key trigger with a simultaneous-press condition fires when, while holding down all keys except the last one in the condition list, you press the last key. For example, if you specify “1 + 2” as the key trigger condition, it fires when the “1” key on the keyboard is pressed first and then the “2” key is pressed. Conversely, if you specify “2 + 1” as the key trigger condition, it fires when the “2” key is pressed first and then the “1” key is pressed. Please note that these are different behaviors.
If you want to use a long press as the trigger condition, turn ON the “Long press” checkbox. If only one key is specified, the key trigger fires on a long press of that key alone. If multiple keys are specified, the key trigger fires when you long-press the last key while holding down all keys except the last one in the condition list. A long press is recognized as a continuous press of two seconds or more. A press of less than two seconds is recognized as a simple press.
To clear an entered condition, click the “Clear” button.
Key assignment settings for the control pad
This screen lets you configure key assignment settings for operating this product with the separately sold control pad connected to it.
The method for setting key triggers is the same as for a USB keyboard. The difference is that the control pad has a dial. For dial operations, you can specify counterclockwise rotation, clockwise rotation, and pressing the dial in, each as a trigger condition. However, the following combinations cannot be set.
Conditions that include dial rotation where the dial rotation is not the last condition
Conditions that include dial rotation and have a long press specified
Customizing main unit button operations
This screen lets you configure key assignment settings for operating this product by customizing the button operations on the main unit of this product.
The method for setting key triggers is almost the same as for a USB keyboard and a control pad. However, for consistency with the operation of this product, there are restrictions on the conditions that can be used for key assignment settings.
The following operations are used by default as keys for operations on the status screen and in the menu, so you cannot assign other functions to them using key assignment settings. However, the operations marked with an asterisk (*) (pressing the A or B button on the status screen, and pressing the 3 streaming button indicators within the menu) can be assigned other functions only when in their respective states.
