New Version 21.09.20

Sep 16, 2021

Version 21.09.20 is now available for DOWNLOAD!

This main purpose of this version is to fix a major new bug in previous version 21.08. We hope for this to become the new recommended stable version.

  • Fixed File > Save (Ctrl-S) immediately after File > Close (Ctrl-W) can corrupt a saved project.
  • Fixed Add Custom Video Mode > Frames/sec was not accepting some legitimate values.
  • Fixed encoding HEVC without hardware encoder (x265) would always output 10-bit instead of 8 (broke in v20.11.28).
  • Changed Copy the filters to only copy enabled filters.
  • Changed fading on the Timeline to automatically fade the opacity when it is not the bottom video track.
  • Expire old QML cache items at startup to reduce app data footprint.

    These must be in the same folder as the corresponding MP4 file and proxy mode enabled.

    This can be used to create so-called Tiny Planet videos.

Note

Please be aware there will be a one-time conversion of cached thumbnails and waveform data when you first run this version. The old database will be kept so if you downgrade or run an older version you still have that older cache to rely on. You can remove either db.sqlite3 (old) or thumbnails (new) in the app data directory to cleanup the old cache or to re-run the conversion to the new file-based cache.

New Version 21.05.01: Time Remap

May 2, 2021

Version 21.05.01 is now available for DOWNLOAD!

WARNING

Projects created with this version can NOT be directly loaded by a previous version. Only versions 21.02 and 21.03 can repair projects created in this version by removing all Time Remap filters.

Time Remap and Speed Ramping!

Usage requires knowledge of how to use Keyframes. Basic, quick-start usage is Filters > Time > Time Remap > Keyframes. Go to this forum post for more usage information.

  • If you try to use it on a video clip with B-frames (a video encoding technology) Shotcut will show the Convert to Edit-friendly… dialog.
  • This filter cannot be disabled.
  • This filter does not support simple keyframes or filter trimming.
  • This filter can not be applied to tracks or the timeline output.
  • Disabled Smooth keyframes for Time Remap to prevent unexpected direction changes.

Apple Silicon (M1) a.k.a. ARM64

We now have a native (not using Rosetta 2) build working on Apple M1 devices! This is not yet a universal app, maybe later in the year for that. This build does not support JACK Audio. Get shotcut-macos-ARM64-210501.dmg.

New

  • Added a new filter Time Remap in the new Time category that affects both audio and video.
  • Added an Apple Silicon build.
  • Added an option to Ignore missing files in Export > Export File (blocking dialog added in v21.01).
  • Added a suggested file name to File > Export Frame… and remembers the last chosen format. These changes make this feature more convenient.
  • Added a button in the Keyframes parameter track header to vertically zoom in to the minimum and maximumn values.
  • Added a Use Sub-clip checkbox to the Convert to Edit-friendly dialog, under Advanced. This will convert only the trimmed portion of a clip plus up to 15 seconds before the in point and after the out point for a timeline clip. When this is on, only the selected clip is replaced and not every clip based on the same source. This option is especially convenient for use with Time Remap in which case it defaults to on if the clip has been trimmed.
  • Added a Keep Advanced open checkbox to the Convert to Edit-friendly dialog that remembers your choice between sessions.
  • Added a status message tip about useful keyboard modifiers to use when dragging keyframes.
  • Added the display of minimum, maximum, and midpoint values to the vertical axis of curved parameters in Keyframes.

Changes

  • Improved the sound quality for Properties > Pitch Compensation when Speed is between 0.5 and 2.0.
  • Changed Keyframes when trimming a clip or filter to move, delete, or disable full keyframes.
  • Upgraded FFmpeg to version 4.3.2
  • Upgraded Rubberband (pitch) to version 1.9.1
  • Upgraded MLT (engine) to pre-release version 7.0.0
  • Improved the color accuracy of the video preview.
  • Converted all numeric text fields in filters to spinners.
  • Reduced memory in audio resampler per clip.

Fixes

  • Fixed black frames in slideshow (broken in v21.02).
  • Fixed Export Frame dialog reappears (broken in v21.02).
  • Fixed Opacity filter may misbehave when using all smooth keyframes.
  • Fixed Export > Format = flac does not write a file with a duration.
  • Fixed using the mouse wheel over zoom sliders in Timeline and Keyframes.
  • Fixed an incorrect path to a file in proxy mode when the path starts with the name of a sibling folder.

  • Fixed a possible crash on setting Properties > Speed higher than 23x.
