caption.burn: burn subtitles into video
Burn static styled subtitles into a video from SRT, VTT, or ASS, with auto-transcription and multilingual auto-detect.
API Platform
caption.burn is live. Pass an SRT, VTT, or ASS file and Rendobar burns styled subtitles directly into the video. Skip the subtitle file and it auto-transcribes the audio first, then burns the result.
- Language is auto-detected, so multilingual sources work without a flag.
- Font, size, weight, position, and wrapping are pixel-matched to the layout you request. Custom fonts load through a fonts directory.
- Shares the same caption engine as
captions.animate, so styling stays consistent across both job types.
See the caption.burn reference for parameters and presets.
Word-level animated captions are a separate job, covered in the captions.animate reference.
