Stage 2 of 3 for adding split clip support in Remotion Studio.
Blocked by stage 1.
Goal
Expose splitting for one selected clip in the Studio timeline.
Scope
- Add
splitSelectedTimelineItems()or equivalent Studio timeline action. - Wire the action to the Stage 1 API for exactly one selected sequence row.
- Show a success notification after splitting the clip in source.
- Show clear feedback when the current selection is not splittable.
- Register
Cmd+Shift+D/Ctrl+Shift+D. - Ensure the shortcut does not interfere with existing
Cmd+Dduplication. - Add a scissor toolbar button using the Studio's existing button/icon patterns.
- Disable or no-op the button when the selected clip is not splittable.
Tests
- Timeline keybinding test for
Cmd+Shift+D. - Timeline action tests for supported and unsupported selections.
- UI-level coverage for button enabled/disabled state where practical.
Out of scope
- Splitting multiple selected clips.
- Complex dynamic codemod support beyond Stage 1.
