Burn captions into a video before it goes out, such as a launch film, a product demo, a reel, a short or a talking clip, from words with times you already have (a speech-to-text JSON, an SRT or VTT file, or a demo's steps.json). Draws them word by word (karaoke, the spoken word lit) or line by line, in the fonts and colors of the product's own site, inside the space TikTok, Reels, Shorts, YouTube, X and LinkedIn leave free of their buttons, and writes captions.srt, captions.vtt and captions.ass to go with the video. Use it whenever a video needs captions or subtitles, or the user asks for them to read with the sound off.
