Why these settings

The caption style is the one from our talking head with b-roll 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.

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".
