add_caption_track
shallowai.morphareels/morpha · Verify this server
Build a caption track from pre-timed lines (e.g. derived from transcribe_clip's word timings). mode "line-sync" (default) creates one text layer per line, each shown only during its [startFrame, endFrame) window via hold-eased opacity keyframes — the active-line karaoke read; mode "static" makes a single layer with all lines joined. `style` picks a preset look. Lines default to a lower-third band. The caption layers are always wrapped in a "captions" group so they don't clutter the layers list. Returns the created text element ids plus `groupElementId` (the captions group).
