Frequently asked questions
- What if my video has multiple subtitle tracks?
- SnapOtter detects all embedded subtitle streams and lets you choose which one to extract. You can extract multiple tracks if needed. All processing runs locally on your self-hosted server.
- Can I extract subtitles from any video format?
- SnapOtter supports extraction from MP4, MKV, MOV, and WebM containers. The video must have an embedded subtitle stream; this tool does not generate subtitles from audio. Processing happens on your own server.
- What format is the output?
- Subtitles are extracted as SRT files, the most widely supported subtitle format. SRT is plain text with timestamps, making it easy to edit or translate. All extraction happens locally on your infrastructure.
