Cost of 4K AI video: three 10-second Omni clips at 4K is $11.25

4K costs three times 720p on Gemini Omni Flash 1.1. One 10-second clip is $1.25 at 720p, $1.875 at 1080p and $3.75 at 4K on Sume, so three clips cost $3.75, $5.625 and $11.25. Clips on this model run 3 to 10 seconds.

fal lists Omni Flash 1.1 at $0.03, $0.10, $0.15 and $0.30 per output second for 360p, 720p, 1080p and 4K (read 2026-10-07). Sume bills the list times 1.25.

Three clips, four resolutions

Each row is rate times seconds times clip count.

Where 4K earns its price

4K adds $1.875 per 10-second clip over 1080p, which is double the 1080p price. Use it for clips that will be shown large or cropped hard.

A crop is a good reason to buy 4K. If you plan to cut a 16:9 frame down to a tight 9:16 crop, the 4K source keeps more pixels in the crop than a 1080p source would. The video filter job crops a hosted clip for $0.02, so the crop itself is cheap; the source resolution is the real cost.

One test run saves money. Render the clip once at 360p for $0.375, check framing, then buy 4K for the one that works. Skipping the check and rendering all three at 4K costs $11.25, against $4.875 for three drafts and one final.

• Resolution is the only variable that moves the per-second rate.
• Duration is limited to 3 to 10 seconds for this model.
• Native audio is always on, so it is part of the clip price.

Shorter clips at 4K

The clip length is the other lever. Omni accepts 3 to 10 seconds, so a 4K clip at the short end is cheaper than one at the long end by the same ratio. A 3-second 4K clip costs $1.125, a 5-second one $1.875 and a 10-second one $3.75. If a shot only needs three seconds on screen, ask for three; the price falls in a straight line with duration.

Cutting a long 4K clip down afterwards does not refund the unused seconds, since billing is by the seconds generated. Decide the length before you submit.

A mixed plan

A practical split is to draft every shot at 360p, keep the good framings, then render only the winners at the higher resolution. With 12 shots of 10 seconds, drafts cost $4.50. Rendering 3 winners at 4K adds $11.25, for a total of $15.75. Rendering all 12 at 4K directly costs $45.00.

The saving depends on how many drafts you discard. If you keep 6 of 12, the same plan costs $27.00, still below the direct figure.

Plan the wallet

Four 4K clips of 10 seconds hold $15.00 while they run. Each reserve is released or captured when the job ends. The 2K or 4K comparison covers upscaling as an alternative, and how far $20 goes shows the same rates at smaller totals.
