Pick the hook frame of an ad with video inspect stills
Sume video inspect returns 8 mid-bin stills by default, or 1-24 at timestamps you choose, plus optional transcription. Find the best opening frame fast.
Call video inspect on a Sume-hosted ad and it returns 8 mid-bin stills by default, or stills at 1-24 timestamps you pass in frames.at[]. Look at the first seconds side by side, choose the opening frame, then cut or regenerate. Optional transcribe: true adds a transcript. See Video inspect.
Frame options
Pass exactly one of at[] or fps. Stills default to jpeg; png is available.
| `frames` value | Result |
|---|---|
| omitted | 8 mid-bin stills (1 fps if the clip is under 8 s) |
false | Probe only, no stills |
{ at: [seconds] } | 1-24 explicit timestamps |
{ fps: n } | Sampling rate, capped at 24 stills |
Cost
Probe and stills are billed by their Modal compute. Transcription is $0.01 per audio minute (list prices from Sume's catalog rate card (GET /v1/catalog), confirmed in the repo's catalog file read 2026-10-03). The default mode is sync, waiting up to 30 seconds.
Typical use
Sample frames at 0, 0.5, 1, 1.5 and 2 seconds of each hook variant, and compare which one shows the product or face fastest. Then use video trim to cut the winner.
