[JIMLN] Release Notes v.6.x

Version 6.5


  • Updated links in the DMG with the correct v6.5 resources.

  • Fixed a rare crash in Just Control, particularly related to channels with a significant number of errors.

  • In the “Device” tab in Just Control’s configuration panel, there is a new “Open REST API” button that will open your default browser to show the API documentation.6.5.0.B1.1248

  • Resolved an issue when using an external audio device that could result in a delay between audio and video if there was no input available when the channel was started.


  • The “Cache Options” channel setting has been replaced with “Dropped Frames Strategy” with the options “Duplicate last valid frame” and “Add black frame”. When frames are dropped from the input (resulting in a gap between two frames), the former will “fill” the gap with duplicates of the last frame before the gap, the latter will “fill” the gap with black frames, making the gap easier to find in post production. In both cases, audio for the inserted frames will be silence.


  • Fixed an issue that could cause connection and performance issues with NDI channels.

Version 6.1


  • Removed irrelevant “Invalid XML” errors in just:control related to running a port service scan on a channel’s port.


  • Improved stability in the API server at port 8080.


  • Resolved an problem that could cause performance issues recording H.264 or H.265 (HEVC) on certain systems.


  • Stability and performance improvements..


  • The API exposed for just:in Mac now implements the Cross-Origin Resource Sharing (“CORS”) mechanism, in particular the HTTP “OPTIONS” method, thus allowing a browser-based user interface to connect to multiple channels with different IP addresses.


  • API requests sent with an “Origin” header field now return “Access-Control-Allow-Origin” in the response. This means that the machine’s IP address and “localhost” are both valid and can be mixed in calls from a web browser.

  • Calls to /ingest/startRecordingWithFilename now have additional checks for valid channel configuration and valid signal before execution, and a “400 Bad Request” is returned in the channel cannot record. These checks mirror those already in place in just:control to prevent a channel entering an invalid state.


  • An interactive “Swagger UI” for testing the API is now published at “/swagger-ui/index.html” on the system running Just In Engine.

  • Most “400 Bad Request” responses now include an “error” property in the response body to indicate the reason that the request failed.


  • Updated the OpenAPI specification published at “/v3/api-docs” to include the latest changes related to naming presets.

  • Fixed a bug that resulted in a “400 Bad Request” response to an API request with a body larger than 2KB.

  • All API requests are now fully type-checked against the OpenAPI specification.

  • Sending an “/ingest/startRecordingWithFilename” request now results in a “400 Bad Request” response if the channel is already recording. Other related calls (e.g. changing naming, capture or destination preset) also result in a “400 Bad Request” response while recording.

  • Sending API requests to a disabled channel now result in “400 Bad Request” responses.

  • Fixed naming inconsistencies between just:in Mac and just:in Linux, all requests to the just:in Mac API now match those specified in the OpenAPI documentation.


  • Resolved a memory leak when writing to an AVFoundation container.


  • Fixed a memory leak and resulting crash caused by an NDI source not matching the channel’s specified format (e.g. frame-rate, resolution, scan).


  • Fixed a bug that resulted in NDI channels reverting to Computer Time timecode source each time the channel was started.

  • Improved stability and performance receiving NDI streams.

  • Fixed a bug that could result in invalid capture presets after re-configuring an existing preset.

  • Golden master.


  • Improved performance when recording H.264.

  • When using LTC timecode over audio, 25, 29.97 or 30fps timecode is now automatically converted to match a channel configured for 50, 59.94 or 60fps instead of flagging the timecode as invalid. For example, a 1080p50 channel can now receive p25 LTC timecode.

  • Golden master.


  • Golden master.


  • Updated all copyright notices to 2024.

  • Golden master.


  • Improved performance when recording HEVC/H.265. Additionally, the correct profile is automatically selected depending on whether the input source has 8 or 10-bit video.

  • Fixed a bug that caused memory consumed by Just In Engine to increase continually when an NDI source without audio was selected, eventually causing a crash and/or the system to run out of memory.

  • NDI sources that switch between sending video only without audio and then video with audio are now supported.

  • Golden master.


  • Golden master.

  • The activate license is now synchronised with the online license every 30 instead of 7 days.
