Overview
The caption editor lets you review, correct, and refine captions for any language — source or translated. Every edit is non-destructive: changes save as a new version without overwriting the AI-generated original. The editor supports 50-level undo, split mode, find & replace, speaker management, and extensive keyboard shortcuts.
Opening the editor
From the video workspace, click on any language track to open the editor. The video player syncs with the active caption segment, and the waveform displays the audio timeline.

Split mode
Split mode lets you divide a caption segment at any word boundary. This is useful when one segment contains two sentences, or when you need finer timing control.
- Select a segment and press S to enter split mode
- Use ← / → to position the split cursor between words
- Press Enter or Space to split at the cursor
- Press Esc to cancel and exit split mode
Find & Replace
Press Ctrl/⌘ + F to open Find & Replace. This searches across all segments in the current caption track — useful for correcting repeated errors like mistranscribed names.
Version switching
Every save creates a new caption version. Use the version selector in the editor header to switch between versions — including the original AI-generated captions and any manual edits.
Saving
Changes save automatically. Press Ctrl/⌘ + S to force an immediate save. The editor maintains a 50-level undo history within each editing session.
