Designing video ads that work with the sound off
Many feed placements start video muted, so an ad has to communicate without audio. That means a visual hook, on-screen text that states the message, burned-in captions for any speech, and a product shown rather than described. Ads built this way still work with sound on; ads built for sound often fail muted.

Test it muted first
Watch every cut with the sound off before launch. If you cannot tell what the product is and why to care within a few seconds, a large share of viewers will not either. This single check catches more problems than any other.
Techniques
- Lead with a visual that explains itself: the problem or the result on screen.
- Add a headline overlay in the first frame that states the hook in a few words.
- Burn in captions for every spoken line, inside the safe zone.
- Show, don't describe: demonstrate the feature instead of narrating it.
- Put the call to action on screen, not only in the voiceover.
Where sound matters more
Vertical, creator-led placements such as TikTok, Reels and Shorts are often watched with sound, and trending audio or voice can carry the ad. Meta lists sound as strongly recommended for Reels. Even there, captions help, because some viewers will be muted and captions also aid accessibility.
Caption style
| Do | Avoid |
|---|---|
| High contrast against the footage | Thin text over busy backgrounds |
| Short lines, a few words each | Full sentences across the frame |
| Timed to the speech | Captions that drift out of sync |
| Inside the safe zone | The very bottom of a vertical frame |
