Change to Menus

Please be aware the menus in Timeline and Keyframes have changed in this version, and different is not a bug. They are no longer a popup or native-OS menu. Rather, they are embedded within the panel and must shrink and offer scrolling based on the size of the panel. To fix a bug with menus not opening for some, we had to switch to a new API because the API we were using is deprecated and no longer supported. The new menu API also does not show keyboard shortcuts in the menus right-aligned because it no longer shows keyboard shortcuts - we had to add that to the menu item text. The upside is that as more of the UI is converted to the API, it will work better with fractional display scales (i.e. 150% or other not multiple of 100) and have a chance to offer the modern Windows or (Android/Google) Material themes.

Fixes

• Fixed dropping multiple files to Playlist in a new project (broken in v19.12.31).
• Fixed some broken keyboard shortcuts in the Turkish translation.
• Fixed Properties > Speed not working after a project file repair.
• Fixed clip selection after Insert Track or Remove Track.
• Fixed Playlist > Add Selected to Timeline creates corrupt clips (broken in v19.12.31).
• Fixed Settings > Display Method > Software (Mesa) on Windows (broken in v19.12.31).
• Fixed creating a Project folder with leading or trailing spaces.

• Fixed seeking previous & next on the first track in Keyframes where you trim a filter or use simple keyframes.
• Fixed an unexpected transition is created when moving a clip rightward adjacent to the next clip in Timeline (regression in v19.12.16).
• Fixed drag-n-drop from Source player to Timeline left player in an inconsistent state (broken in v19.09.14).
• Fixed an inconsistent colorspace conversion when accessing a cached image.

• Fixed clicking on the rectangle control may change its size.

Changes

• Improved the reliability of Timeline > Select None.
• Changed Timeline > Master > Properties > Frame rate to show 6 decimal digits.
• Reduced the latency of scrubbing (regression in v19.12.31).
• Changed the video-overlay rectangle control used in some filters to allow changing the position by dragging from anywhere inside the rectangle.
  To enable, one must first double-click the center circle to put it into a positioning-locked mode. Otherwise, you would be prevented from dragging the clip out of the Source player.
• Changed the Filters panel on macOS to prevent floating to avoid a frequently reported problem of the Filters window appearing blank/black.
• Changed Timeline > clip context menu > Detach Audio to not seek afterwards.
• Improved mouse wheel and trackpad behavior in Timeline.
  Now, you do not need to ensure the mouse pointer is over a clip, speed is reduced, and zoom keeps focal point in view. The new zoom behavior does not apply when using the option Center the Playhead in the timeline menu.
• Upgraded MLT to version 6.20.0 and WebVfx to version 1.2.0.

New

• Added Settings > Preview Scaling!
  This reduces the resolution for rendering effects for preview within the app, but there may be added a fair cost to the CPU for down-scaling sources to the preview resolution. Thus, this will be more beneficial when low resolution proxies are created, which is planned for version 20.04 in April.
  Please understand that preview scaling will not always provide perfect fidelity. Some differences are unavoidable especially where blur, softness, and noise are concerned.
  Some filters may not support preview scaling and will process at full project resolution:
  • Choppy
  • Rutt-Etra-Izer
  • Stabilize
  • Text: HTML > Blank with Web Animations
  • Text: HTML > Simple Scroll
  • Text: HTML > Two Column Scroll
• Added Export > Advanced > Video >Use preview scaling.
  This is intended to provide a faster export for draft review. You should leave the export resolution set to the project resolution unless your preset or video codec dictates a resolution.
• Added Views > Scopes > Video Vector.
  Note that the graticule on this is non-traditional, inspired by Alexis Van Hurkman.
• Added Filters > Audio > Pitch.
  This is handy when changing the speed of a clip anywhere from 4.0x - 0.25x.
• Added the ability to rename clips in Properties by clicking into the header where the name is displayed.
• Added support for using a video clip in Transition Properties > Video.
  This is handy to use with @jonray's matte transitions.
• Added a few more export presets:
  • audio/ALAC
  • audio/FLAC
  • intermediate/DNxHR HQ
  • intermediate/ProRes HQ
  • intermediate/ProRes was changed to ProRes 422
• Added Arabic translation.

• Changed the Filters panel on macOS to prevent floating to avoid a frequently reported problem of the Filters window appearing blank/black.

• Added Filters > Video > Rectangle.
  Note that on Windows and macOS whenever a new instance of the Rectangle filter occurs (add filter, split clip, export, etc.) a window will pop up very quickly and then disappear. This is strange but expected at this time with no plan to address it for release.
  This is an experimental video filter that uses the Qt Quick QML side of WebVfx.
• Added Filters > Audio > Pitch.
  This is handy when changing the speed of a clip anywhere from 4.0x - 0.25x.

Unfortunately, version 19.12.16 introduced a major new bug when moving clips on the Timeline with Ripple on. This version not only fixes that but also includes a highly requested feature that was a year end goal: moving multiple clips on the Timeline! In addition, two more video scopes were added: RGB Parade and RGB Waveform.

Other Changes and Fixes

• Allow reducing track height to very short in Timeline and Keyframes.
• Fixed crackly audio playback for some Windows users.
• Fixed loading project files made before v19.06 when not using a period for a decimal point.
• Fixed Lift and Ripple Delete on Timeline not reliably removing all selected.
• Fixed checking Properties > Image sequence may not update duration in Playlist.
• Fixed the intra-VLC and non-linear-quantizer options in the XDCAM-422 and D10 export presets.
