Check the export against your video

This changes subtitle format and whole-cue timing; it does not transcribe audio or burn captions into a video. Check the first, middle and last captions in your editor before publishing.

Up to 2,000 cues and 200,000 characters. NOTE comments are omitted. SRT output drops WebVTT cue identifiers and positioning settings. Markup is kept as text, so player support may differ. STYLE, REGION, timestamp maps and inline karaoke timing need a subtitle editor.
