Mobile in-app specs
Small screen, muted start, thumb on the skip button.
The same video master runs as interstitial and in-stream video inside mobile apps — a screen a few inches wide, often with the sound off.
Placement
| Format | Interstitial and in-stream video · the 16:9 master runs full-width |
| Durations | 6–30s · shorter cuts finish more often |
| Sound | Varies by app — assume muted starts |
Designing for a small, silent screen
Burn captions into the video — muted autoplay is the norm, and captions are the difference between a skipped ad and a read one. Land the brand inside the first two seconds. Check your key frame at five-inch scale: if the product is not legible on a phone held at arm’s length, recut before spending.
