New Version 20.04.12: Speed Pitch Compensation and Replace

Apr 12, 2020.

Version 20.04.12 is now available for DOWNLOAD!

The proxy management feature is not ready, but we worked on a building block in the form a Replace edit command that is integrated into Reverse and Convert to Edit-friendly. This will be used to asynchronously integrate proxies after they have been generated.


  • Added Properties > Speed > Pitch Compensation for automatic pitch correction for speed changes > 0.1x.
  • Added a Replace command to Timeline clip menu including blank regions with shortcut R.
  • Properties > Reverse now automatically replaces a selected clip on the timeline (or in Source player if using that).
  • Added 15 second handles when using Properties > Reverse on a timeline clip. Handles are extra footage before the in point or after the out point. This makes it easier to adjust edits or add transitions around reversed clips.
  • Added Properties > Duration > Timeline to show (not editable) the duration of a timeline clip.
  • Added a Corner Pin video filter (thanks to @sauron in the forum for the initial effort).

  • Added a Properties > Convert button to make Convert to Edit-friendly in the menu more convenient (kept in the menu for now because a number of support tips reference it).
  • Properties > Convert now automatically replaces respective clips in Source and Timeline and adds its clip to the Playlist.


  • Fixed = in Text: Simple filter ignores all text before the sign (broken in v20.02).
  • Fixed a crash when using some video filters with Preview Scaling and multiple video tracks:
    • Choppy
    • Rutt-Etra-Izer
    • Swirl
    • Text: 3D
    • Text: HTML
  • Fixed Offset X and Y parameters of Rotate and Scale filter with Preview Scaling.
  • Fixed video artifacts when using a video for a custom transition and Export > Parallel processing.
  • Fixed video artifacts when using the Distort video filter and Export > Parallel processing.
  • Fixed video artifacts when using the Rotate and Scale or Size and Position filters, multiple video tracks, and Export > Parallel processing.
  • Fixed missing code-signing entitlements for macOS that caused crashes when using the following (broken in v20.02):
    • Open Other > Audio/Video Device
    • HTML-based video filters:
      • Choppy
      • Crop: Circle
      • Crop: Rectangle
      • Rutt-Etra-Izer
      • Swirl
      • Text: 3D
      • Text: HTML
  • Fixed floating or docking some panels may crash on some Linux systems:
    • Filters
    • Keyframes
    • Timeline
  • Fixed changing the name of a track in Timeline when leaving the field without pressing Enter.
  • Fixed File > Export Frame exports uses Preview Scaling instead of project resolution.
  • Fixed switching between Cut and Dissolve in transition properties.
  • Fixed project not modified when changing transition properties.
  • Fixed pressing Enter in Filters search may open a playlist item.
  • Fixed a regression in JACK transport control (broken in v19.12).
  • Fixed a missing Timeline track Lock button animation when lock prevents something.
  • Fixed clips can be moved to locked timeline tracks (broken in v19.12).
  • Fixed treating paths with Windows drive letters as relative on macOS and Linux.
  • Fixed automatically relinking filters with HTML files (when app location changes or moving projects).
  • Fixed Undo followed by Redo after a Lift or Remove on a transition saves the transition as INVALID.
  • Fixed some filters than use external files broken when using network (UNC) paths on Windows:
    • LUT (3D)
    • Mask: From File
    • Text: HTML
  • Fixed Filters > Copy & Paste does not keep filter in and out points.
  • Fixed opening with a file from the command line on Linux snap or portable.
  • Fixed Export can overwrite a source when run from command line.
  • Fixed Keyframes previous/next buttons not using the parameter track to which they belong but rather the current track.
  • Fixed opening a playlist clip or a new clip breaks filters on Timeline > Master if it is selected.


  • Changed Export > Video > Parallel processing to default to OFF but also now it save the state between export jobs and app session.
  • Added support for FFmpeg sample_fmt option to Export > Other.
  • Automatically disable parallel processing on add-on bigsh0t (360) video filters.
  • Stop adding title="Anonymous Submission" to MLT XML.
  • Increased the priority of background jobs a little on macOS and Linux (still less than normal).
  • Added 448k to Export > Audio > Bitrate.
  • Added automatically scroll the Timeline when you double-clock a clip to select-and-seek.
  • Updated the mouse wheel behavior in Keyframes to match the changes to Timeline in version 20.02.
  • Added an option to place an icon on the Desktop to the Windows installer.
  • Add a cursor to the Audio Waveform scope.
  • Removed Export > Stream as it is not supportable in its current state.
  • Changed shortcuts C and Ctrl+C to work with the clip under the playhead of the current track if no clip is selected. This makes it behave similar to other editing shortcuts.
  • Changed the keyboard modifier for skim to Shift+Alt. This prevents Shift (previous modifier) when selecting multiple clips from changing playhead position. NOTE: On macOS, in order to scroll Timeline or Keyframes horizontally with a mouse wheel (not Magic Mouse or track pad), you must also use one of the following:
    • Control
    • Control+Option
    • Control+Command
    • Option+Command
  • Changed the Matrix parameter of the Dither video filter to be a drop-down combo box without keyframes support.
  • Changed Alpha operation > Write On Clear to Overwrite on some video filters to make them more clear:
    • Mask: Simple Shape
    • Chroma Key: Advanced
