Questions & answers
How do I use Edit subtitles?
Import SRT/VTT, edit text and timing offsets, then save subtitles or package them with video.
What limits should I know about?
Packaged subtitles are optional tracks, not text burned into frames. Display depends on the player; keep SRT/VTT as a fallback.
