Shotcut 20.04.12

What's new in this version:

New:
- 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

Fixes:
- 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 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

Changes:
- 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
