Should I burn captions into my video?
Burn them in for short-form social (TikTok, Reels, Shorts, X). Deliver SRT for long-form (YouTube, Vimeo, courses, sermons).
Detail
Whether to burn captions in or deliver them as a separate SRT/VTT depends on the destination. Short-form social platforms (TikTok, Instagram Reels, YouTube Shorts, X, LinkedIn feed) don't support uploaded caption files in a way that survives cross-posting — the captions either live in the player and disappear on download, or aren't supported at all. For these, burn captions into the MP4 file. Long-form platforms (YouTube long-form, Vimeo, sermon livestream platforms, e-learning LMSes) support uploaded SRT or VTT and render captions in the player UI. Soft captions are the right choice here because viewers can toggle, switch languages, and adjust styling. Most professional captioning rules: burn-in for social, soft caption for long-form.

SRT for almost everything: video editors, YouTube, Vimeo, every major platform. VTT only when you're embedding video on a website with HTML5 <track>.
Yes. YouTube indexes uploaded SRT/VTT transcripts in its search index. A clean transcript lifts discoverability 20–30% over auto-captions.
