## About

## What it does
Video Subtitle Burner burns SRT subtitles into a video and returns the processed video as a binary file.

Send a video file and an SRT subtitle track in the request body. The video file can be up to 100 MB. The subtitle text must be provided in SRT format as multi-line text. The endpoint handles the video overlay step and gives you the finished video back as binary output.

Use Video Subtitle Burner when you need hardcoded subtitles for social clips, course videos, product demos, or accessibility-focused exports. It fits workflows where you already have a subtitle file and want the captions permanently embedded into the video rather than delivered as a separate track.

Because the response is binary, you can stream or save the result directly into your storage, media pipeline, or download flow without an extra conversion step.
