Frequently asked questions
- What subtitle formats does it output?
- It generates SRT and WebVTT files, which are compatible with virtually every video player, editor, and hosting platform. The generated files include precise timestamps for each caption segment.
- Can I use this for videos not yet released publicly?
- Yes, that is one of the primary benefits. Since SnapOtter is self-hosted, your video audio never leaves your server. This is ideal for pre-release content, internal communications, or proprietary footage.
- How well does it handle overlapping speech or accents?
- The underlying AI model is robust with varied accents and conversational overlap, though heavily noisy sections may need manual review. All processing happens locally, so you can iterate and re-generate without usage caps.
