Video Mode: Select the Video mode and ensure that it matches the NDI® Source. If it does not match, a warning will be shown (“No Signal” or “Wrong Signal”). If you plan to run your Channels in “Auto” mode (with automatic signal format detection) you can select “Auto” from the Video Mode dropdown menu. This enables the automatic signal format detection and the Channel will automatically sense and recognize a proper NDI source and change the video mode accordingly.

NDI source has no audio: This setting disables the audio reception delay within the NDI pipeline. The pipeline's default behavior includes a delay to accommodate expected audio. In scenarios where audio input is not present, enabling this option optimizes performance by removing the unnecessary delay.

Audio Input: Choose between different Audio Input options. Audio Input options are:

• Auto (same as video, NDI source)

• External: When utilizing the External option, a channel can utilize any audio input available within the macOS Sound input preferences as the audio source. Therefore, USB audio interfaces such as the Focusrite Scarlett 2i2, MOTU M2-M6 and many others are supported. Furthermore, the Dante Virtual Soundcard can be utilized as an Audio Input option. Additionally, a delay in frames for the video pipeline can be added here. Please note that the delay option is only available when using the External Audio Input option.

File Overwrite Strategy:

• Append Counter (Default): When using this option, the Just In Engine application will add “_2” to the actual file name to avoid overwriting an already existing file.

• Replace: By choosing this option, the Just In Engine application will overwrite a file with the same name at the target location.

Chunk Length: Defines the maximum length of the recorded Video. The maximum Chunk Length is 12 hours, the default option is “2” hours.

• If the Recording does not reach the entered Chunk Length, the recorded clips will be automatically truncated to the expected recorded length.

• Recording exceeds the entered Chunk Length: A new Recording (generating a new clip) will automatically be started.

Timecode Mode: NDI channels now have an additional “Timecode mode” setting with the options “NDI UTC Timestamps” and “SMPTE Timecode”. The former expects frames with standard NDI UTC timestamps, as provided by the majority of NDI devices. The latter expects SMPTE timecode encoded as 100ths of a nanosecond. This may be useful with some devices, such as the AJA Bridge that takes embedded SDI SMPTE timecode and converts it for use with NDI. When “SMPTE Timecode” is selected for the channel, “SDI Embedded” is additionally available as a timecode source, allowing you to see the embedded timecode sent with the stream.

Start Timecode: Enabling this option overrides the local time or incoming timecode and makes every new clip start with the defined timecode value.

Port: port to access the Channel from Just In Mac Pro 2026 over an IP connection. The default port for the first Channel is “50000”, “50001” for the second Channel, and so on. You can leave this setting as is if the chosen ports are not in use on this machine.

MXF Write Buffer (Bytes in binary): This setting can be used to tune MXF writing for specific storage requirements, but should only be changed with care as it may lead to unexpected results including write errors. Recommended value: “Block size of storage”.

Restart On No Signal if Not Recording: If this option is enabled, the Channel will automatically restart after a signal loss (only in Idle Mode). Available options are:

• Close container, write to new: Recording to the current file will be stopped and as soon as there is a valid signal again the recording will start into a new file.

• Close container and stop: Recording will be stopped when the Channel detects a signal loss.

Dropped Frames Strategy:

• Duplicate last valid frame: In case of a dropped frame, the channel adds a duplicate of the last valid frame available.

• Add black frame: This option adds black frames for every occurring dropped frame.

Preview

You can manually override the resolution, frame rate, and quality of the Video Previews within Just Control. This may be helpful to increase performance when displaying many Channels in Just Control. Please refer to the Channel Preview Options below for more information.

Resolution: Two resolution options are available:

• High: 640×360px

• Low: 480×270px 

Frame rate: The preview frame rate can be changed between “0” (=native frame rate) and “30” (if the channel frame rate is higher than “30”, then the preview will be limited to 30fps).

Quality: The “Preview Quality” setting can be changed between “10%” and “100%”.

Add/Remove an NDI® Channel

You can add or remove NDI Channels at any time. Open the Just Control Configuration panel and select one of the connected Just In Mac Pro 2026 devices. Then use the “Plus” button to add an NDI Channel.

Once the new Channel is added, you can adjust the settings and enable it so that you can use it within Just Control. To delete a Channel, select the Channel within the “Devices & Channel” list and press the “Minus ” button.

Synchronization

It is generally recommended to synchronize all NDI senders and receivers within the network with an NTP server to ensure precise timing and coordination. This includes all machines running the Just In Engine application.

Configure each machine running the Just In Engine application to use a valid NTP server. This ensures accurate time synchronization across all devices. Although not mandatory, it is recommended to restart the Just In Engine application daily to maintain optimal performance and stability.

Following these steps will help ensure reliable and synchronized operation of your NDI recording.
