[JIML] Channel Settings Blackmagic Design v.6.0

Open

Settings

You can find a description of each Channel setting below:

Device: Select the Video Device (Blackmagic Design) for this Channel.

Input Mode: Select the Input Mode for this Channel. Available options, depending on the Device are:

• SDI (Blackmagic DeckLink)

Input: Choose the Input of the Device for this Channel here (for Blackmagic Design Channels, only option “Input #1” is available).

Audio Input: Choose between different Audio Input (AJA/Blackmagic Design) and Audio Input Channel (AJA only) options. Audio Input options are:

• Auto (only options for Blackmagic Design-based Channels)

Video Mode: Select the Video mode and ensure that it matches the incoming Video Signal, which is attached to the selected Channel. If it does not match, a warning will be shown (“No Signal”).

File Overwrite Strategy:

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

• Replace: By choosing this option, the Just In Mac Lite 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 (02:00:00:00).

• 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.

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

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 a Channel detects a signal loss.

Cache Options:

• Don't Cache: Files are directly written to disk, no caching is done.

• Cache (Default): Tells the internal macOS Ethernet controller to cache data to flush it to the network stack later to improve write performance.

Action on Timecode break:

• Ignore: The Channel ignores timecode breaks.

• Create new file: The Channel creates a new file upon a timecode break.

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” (i.e. native frame rate) and “30” (if the channel frame rate is higher than “30”, then the preview will be limited to 30 fps).

Quality: The “Preview Quality” setting can be changed between “10%” and “100%” (the default value is “50%”).
