What $12.50 buys on Omni Flash: 100 s at 720p, 33 s at 4K

A $12.50 balance buys about 333 seconds of Gemini Omni Flash 1.1 at 360p, 100 seconds at 720p, 66 seconds at 1080p, or 33 seconds at 4K on Sume. In whole 10-second clips that is 32 clips at 360p, 10 at 720p, 6 at 1080p and 3 at 4K, with a few cents left each time.

The division

Divide the budget (1,250 cents) by the billable rate per second. Because Sume rounds each clip up, count whole clips as 1,250 divided by the clip price, rounded down, instead of dividing by seconds.

Sume rounds each clip up to the next whole cent, so a clip total is ceil(seconds x rate), not a sum of fractional cents.

Reading the leftovers

Three 4K clips use $11.25 and leave $1.25, which is exactly one 10 s clip at 720p. Six 1080p clips use $11.28 and leave $1.22, enough for a 9 s clip at 720p (113 cents). The docs say Sume reserves the provider list times 1.25 when you submit, so size your balance for the clip price, not for the per-second rate.

A mixed plan inside the same $12.50

You do not have to pick one tier. One reasonable split is eight 5 s drafts at 360p (8 x 19 = 152 cents), two 8 s finals at 1080p (2 x 150 = 300 cents) and one 10 s 4K hero (375 cents), which totals 827 cents, or $8.27. The remaining $4.23 covers another 3 clips of 10 s at 720p (375 cents).

Whatever the split, check usage.cost on each completed job and keep a running total. The numbers above are catalog list prices dated 2026-08-28, which the catalog says are subject to change.

The same length at every tier

For reference, a 10-second Omni Flash clip at each resolution. Every price is the seconds times the billable rate, rounded up to a whole cent, as of 2026-10-08.

Limits to remember

These apply to every request on this page, from the Video Router and Video generation docs:

• Length is 3 to 10 whole seconds in generation modes; an edit takes no duration.
• Aspect ratio is 16:9 or 9:16; an edit takes no aspect ratio.
• Native synced audio is always on, and generate_audio: false is rejected.
• There is no bitrate_mode, no reference audio and no seed.
• Billing is the provider list times 1.25 per output second, reserved at submit and shown in usage.cost.
