AI VIDEO GUIDE
How to make AI videos with B-roll and captions
Short answer
Start with a finished script, split it into short beats, match each beat with B-roll that shows what is being said, then add captions timed to the narration. Review the result with the sound off — if the video still makes sense, your visuals and captions are doing their job.
Step by step
- Write the script first. Visuals should follow the words, not the other way round.
- Break it into beats of one sentence or idea each.
- Choose B-roll per beat: a concrete image for every concrete claim.
- Add captions in short lines, high contrast, kept clear of platform buttons.
- Watch it muted and at full speed, then fix anything confusing.
B-roll and caption checklist
| Check | Good sign | Warning sign |
|---|---|---|
| Relevance | Footage illustrates the sentence on screen | Generic stock loops unrelated to the point |
| Pacing | Cuts land with new ideas | One clip held through several ideas |
| Caption length | Two to six words per line | Full paragraphs on screen |
| Accuracy | Captions match narration exactly | Misspelled names or numbers |
| Safe zones | Text clear of UI overlays | Captions hidden behind buttons |
Rights and accuracy
Only use footage you have the right to use, and verify any facts in the narration. Captions are also an accessibility feature — accurate captions help deaf and hard-of-hearing viewers, not just muted scrollers.
