1What this hook covers

This hook records subtitle files: whether a tool can export or import them, or says why it leaves captions off. 3 tools document subtitle files, 1 explain leaving captions off, and 24 say nothing.

Subtitles belong in a separate file for most platforms, so they can be switched on, translated and corrected without re-rendering the picture.

2Each reading and its tools

  • SRT and VTT files: Descript, HeyGen and Kapwing
  • Captions left off by design: SceneMixer
  • Not documented in the docs read: Adobe Firefly, BytePlus ModelArk, Colossyan, D-ID, fal, Flixly, Google Veo, Higgsfield, invideo, Kling AI, Krea, LTX, Luma, MiniMax, OpenAI Sora, Pika, PixVerse, Replicate, Revid, Runway, Synthesia, VEED, Vidu and Wan (Alibaba Cloud)

3Tools with more to read

  • Descript — Subtitles exported as a separate SRT or VTT file
  • Kapwing — Subtitles downloaded as SRT, and SRT or VTT files uploaded
