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‚Ķ 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‚Ķ 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.
