Run them after the rough cut, once the words are final. Captions come from the transcript Vyra makes on upload, so they're timed to what you actually said.

Why these settings

  • The caption style is the one from our UGC hook and demo video page. Naming it in the prompt is faster than fixing it afterwards.
  • On TikTok, the bottom of the screen is covered by the post caption, username, and buttons, so captions sit above it.
  • One bigger caption is enough. If every line is big, none of them stand out.
  • The first line on this format is usually something like "I was spending 4 hours on every edit". That's the one to make bigger.

Fixes

  • Captions over your face. "Move captions to the lower third."
  • Wrong word. "At 0:12 the caption should say [word]."
  • Too many words on screen. "Max 3 words per caption."
  • Style doesn't match what you had in mind. Attach a video you like and say "match the captions in this".

FAQ

What caption style fits a UGC hook and demo video? Bold phrases, hook text on screen. To copy a style from another video, attach it and say "match the captions in this".

Can it spell names right? Yes, if you list them. "Spell these as Vyra, sulansart, gesso."
