As this VSE Quick Tasks has been closed on devtalk, I’ll insert it here instead: https://devtalk.blender.org/t/quick-tasks-for-the-video-sequence-editor-a-list-of-suggestions/10341

A list of suggestions for VSE Quick Tasks:

  • Add splice function to remove cuts from the same strip with consecutive frame numbers over a cut: https://github.com/tin2tin/join_through_splits
  • Add Slide, where the adjacent handles are selected but the handles are deselected of the original selected strips. When using Grab the strip position is changed in the timeline, but not the contents of the strip. Insert this function into Slip operators.
  • Add Roll, which trims the In point of one and the Out point of the other, while leaving the combined duration of the two clips unchanged.
  • Add Ripple Trim.
  • Correct linked_handles to the current function to be assigned to (Left/Right setting) to Mouse(which it actually is, but currently must be set to NONE to work).
  • Add LEFT and RIGHT settings to linked_handles so they can be added to the menu: Select > Handles > Linked Left/Right
    This selection is the first step of Roll trimming:
    https://developer.blender.org/T6882
  • When using Slip then auto-select both handles of all selected strips - because with both handles selected inside the strip and Grab performs a Slip.
  • Expose currently active hover state to Python API, so context-sensitive menus and mouse cursors can be added to the VSE.
  • Add hover states to all VSE elements like: Strip-types, handle, adjoined cuts, empty space, playhead etc.
  • Make the Time Sidebar Panel use meaningful values.
  • On import, detect resolution, colorspace, timecode, and aspect of the source clip.
  • In import panel, add checkbox to copy source resolution, colorspace and aspect to Output Dimensions. Default on for first clip like the fps checkbox.
  • Add sort in Filebrowser after timecode.
  • Expose Source Aspect, colorspace in Source Sidebar Panel(Code is already in Movie Clip/Motion Tracker)
  • Support drag and drop of multiple files from File Browser.
  • Delete Proxies(Code is already existing in Movie Clip/Motion Tracker). https://developer.blender.org/D6139
  • Meta, Adjustment Layer, and Scene strips can have both Video and Audio, but audio attributes are missing. The sound sidebar panel needs to be exposed too for these types of strips and also drawing of waveforms on the strips.
  • Scene Strips: Separate Camera Override(using the currently active camera in scene) from Selected Camera. When a camera is selected it is currently not possible to go back to Camera override mode.
  • Menu > Strip > Add Modifier should work on the entire selection, when selected in the menu, but not when selected in the Sidebar > Modifiers menu(unless +Alt is pressed).
  • Speed Effect Panel: The Speed Factor widget needs limits. When in Frame Number, then limit to Number of frames of the active strip. When in Speed, limit to positive values. When in Scale limit to values between 0 and 1(or use a % scale of 1->100). The panel also needs a redesign: https://developer.blender.org/D6110
  • Add Speed Strip for audio strips, it’s basically the pitch value which should be controlled.
  • Let Speed and Pitch determine the out frame value of the affected strips.
  • Add a SMPTE widget for timecodes ex. 11:22:33:44 https://blender.community/c/rightclickselect/c0cbbc/
  • Allow for High Frame Rate (HFR) formatting of timecodes: https://developer.blender.org/T53661
  • API: Add ability for python to pause/resume the ‘strip collision’ detection (like happens in the grab operator) so a python function can move a large number of strips without blender moving the strips up and down.
  • In the Strip tab in the Sidebar, all functions should work on the full selection when +Alt is pressed. Ex. changing the color of a color strip with +Alt pressed should change the color of all selected color strips. Or the font of all text strips should be changed.
  • Expose more ffmpeg options and add the command-line options to the API.
  • Add an outline, multiline options to the texts in the Text Strip: https://blender.community/c/rightclickselect/xTdbbc/
  • Text Alignment of Text Strips: https://blender.community/c/rightclickselect/JQdbbc/
  • Add import of subtitles.
  • Add a meaningful UI widget to replace the Sound Strip Pan widget, designed as a movable position between 5 surround speakers: https://developer.blender.org/T69684#784663
  • Add VapourSynth support in the Blender built-in ffmpeg build: https://github.com/m-ab-s/media-autobuild_suite/commit/1e6181a698816701b4a291dc524c50262ee806ce On VapourSynth: http://www.vapoursynth.com/ RCS: https://blender.community/c/rightclickselect/Cnbbbc/
  • Add “Wait for input” setting to Pick Linked(shortcut: L), Select Linked Handles(Alt+Select), Select Linked Time(Ctrl+Select), so they can be used as tools accessed from the Menu. Maybe useful code: https://developer.blender.org/rBS870b4b673511094cf0beaeaf07305407ccdda47a
  • Batch add single input effect strips to all selected strips.
  • Bug: A stacked pile of effect strips gets randomly autoselected when you try to move a single effect strip(that can be done in the source panel without troubles).
