Omni Flash on Sume: a 4K clip of 3 s is $1.13, 1080p of 10 s $1.88

Resolution on Gemini Omni Flash 1.1 is priced by output second, so a short clip at a high resolution can cost less than a long clip at a lower one. If your 4K need is a hero shot or an opening beat, that changes the plan.

The comparison

fal lists $0.15 per second at 1080p and $0.30 at 4K (page read 2026-10-05). Sume bills list times 1.25, rounded up per job. Omni on Sume runs 3 to 10 seconds, so those are the two ends.

Plan by what the 4K is for

The request is the same as any Omni job, with resolution set to 4K. The API also accepts lowercase 4k as an alias on this model only. Sume sends the provider its own enum value, so you never write the fal spelling.

• A 3-second hero or logo reveal at 4K costs less than a 10-second 1080p clip. Cut it into a longer edit in Timeline.
• For a full 10-second 4K clip, budget $3.75, three times the price of 720p.
• Draft at 360p ($0.30 for 8 seconds) and send only the take you keep at 4K.
