Video inspect on Sume: 8 stills at 768 px and the fast seek option

By default Sume video inspect returns the probe and 8 mid-bin stills with a long edge of 768 pixels. You can ask for 1 to 24 stills with frames.at[] or frames.fps (up to 2), raise max_edge up to 2160, or send frames: false for the probe alone. The source can be up to 1800 seconds. The numbers come from Video inspect, read 2026-10-06.

What does the seek option change?

seek picks how each still is found.

What else does it return?

The default mode is sync and waits at most 30 seconds, then returns 200 with the result or 202 with a queued job. With transcribe: true it runs Sume STT at $0.01 per audio minute, and a clip with no audio track returns inspect_source_has_no_audio. Read probe.has_audio first with a frames: false call.

• Stills are durable media.sume.com image artifacts.
• Probe and stills are billed by their Modal compute; transcription adds its per-minute rate.
• For an accurate frame at the source size use video frames.
