Release Notes

What's new in MovieRecorder & MovieRecorder Express?

  • NEW: Updated NDI SDK to 6.2.1 - r146761, and using new audio sync
  • NEW: REST API: Added the ability to ask MovieRecorder to execute an AppleScript GET /applescripts/My%20Script
  • NEW: REST API: Added support for HTTPS
  • IMPROVED: Scheduled Recordings: Added an option on scheduled recordings to set wether we should  interrupt a potential ongoing manual recording when starting specific scheduled recordings. Previously if a manual recording was ongoing when a scheduled recording should start, nothing would happen.
  • IMPROVED: Scheduled Recordings: If a manual recording is in progress for a source and the user stops it, we now check whether there is a scheduled recording currently planned for that source, and if so, start it.
  • IMPROVED: Scheduled Recordings: If a scheduled recording is planned for the source within the next 5 minutes, do not start the recording, and display a notification. This should make sure you get a warning in case a scheduled recording starts soon.
  • IMPROVED: Minor user interface changes for macOS Tahoe
  • IMPROVED: Performances when recording large frame sizes (8K and up)
  • IMPROVED: Updated menu items icons
  • IMPROVED: Video formats (display modes) are now more consistent
  • IMPROVED: QuickTime None or Segmented Destinations: If the file is deleted while recording (by another computer or process), we will now try to recreate a new file. Note that what was recorded until then will be lost as the file was deleted. Does not work with QuickTime Classic, nor MXF destinations.
  • FIXED: Issues with SD anamorphic not being recorded properly.
  • FIXED: Issues with "loop recordings". In some rare cases we could start writing again at a wrong location in the file.
  • FIXED: REST API: Changing the scheduled recording names would not apply
  • FIXED: REST API: It was not possible to set the start of a scheduled recording to midnight.
  • FIXED: Potential leak with NDI sources

What's new in MovieRecorder?

  • IMPROVED: Scheduler WebUI: Now showing the first day of week depending on system settings. Some browsers do not support it, in that case there is a setting that you can change manually.
  • IMPROVED: MXF Destinations: When using two destinations for the same source, using the same AVPreset, files will now relink easily in Avid Media Composer
  • IMPROVED: MXF Destinations: MXF muxer has been updated to the latest version
  • IMPROVED: MXF Destinations: Now flagging correctly the ProRes flavor.
  • FIXED: Issues with HD codecs using 1440 x 1080 resolution (XDCAM HD, HDV,...). Aspect ratio was not properly set.
  • FIXED: Issues with some XAVC codecs that were not yet compatible. Note that limitations still apply as some flavors require specific frame size and frame rates to work. If not compatible, the encoder may return a "Failed to init encoder" error.
  • FIXED: Potential artefacts when using AVC-Intra.
