Software Update: Shotcut 21.01.29

Shotcut is a comprehensive open source and cross platform video editing program for Windows, Linux and macOS. It uses FFmpeg and therefore has support for the most common audio and video formats. The files are not imported, but are edited in their original format. It can handle different tracks and a mix of formats and resolutions can be used within a project. Version 20.11.25 of Shotcut has been released with the following changes and improvements:

New

  • Added support for AV1 decoding and encoding. A lot of people are unexepectedly downloading AV1 from YouTube, and this makes Shotcut comptible with those files. (Please be aware that AV1 encoding is naturally very slow and that is not a bug.)
  • Added an Advanced mode to the Properties > Convert to Edit-friendly dialog with:
    • Added detection of a HDR transfer function (ITU-R BT.2020 or SMPTE ST2084) to automatically show Convert dialog.
    • Added Convert to BT.709 colorspace that provides HDR-to-SDR tone mapping! This helps a lot of people who are recording games in HDR and were surpised by the poor colors when editing in Shotcut.
    • Added Deinterlace option (bwdif) that outputs one frame for each field.
    • Added Override frame rate and Frame rate conversion with Blend and Motion Compensation options. (Please be aware that Motion Compensation is very slow and that is not a bug.)
  • Added Use Higher Performance Waveforms to Timeline and Keyframes menus (default on).
  • Added a red outline around the thumnbail of the currently opened Playlist item.
  • Added video filter Reduce Noise: Quantization.
  • Added Color space and Color transfer to Properties > Video.
