The prompt
Caption style (Resolve, Text+ or subtitle track, Burn into video): Font: a plain bold sans-serif. Size: about 6% of frame height. Colour: white with a soft dark drop shadow (not a heavy box). Position: on vertical Shorts and Reels, the middle band, clear of the bottom fifth to third and the right-side buttons; on 16:9, the lower third. Line length: about 20-25 characters on vertical, up to about 42 on 16:9, 2 lines at most. Timing: at least about 1 second per caption (longer for longer lines), never across a cut if you can avoid it. Text: [Your line, split at a natural pause]
