- Your media file stays in this browser while the tool runs.
- Short clips work best. Large or complex files may take longer or fail.
- Subtitle text must be valid timed text (SRT or VTT-like format).
- This tool burns subtitles into the video stream, so subtitle text is not a separate file output.
