Break it into short, complete ideas
Reading text and listening to speech take different amounts of time. Split long sentences at natural breaks in meaning instead of placing everything on one screen. Leave viewers time to watch the video too.
Use auto captions as a draft
Check names, brands and numbers in AI-generated captions. Replay the original audio where noise or overlapping voices make the words uncertain, and correct the draft.
Keep it readable as the background changes
Check captions over both light and dark scenes. Outlines or a background can help maintain contrast. Make sure the position does not cover faces or important actions.
Check the display time
Read each caption yourself to see whether it stays on screen long enough. Adjust captions on the timeline if they appear too early or too late relative to the speech.
