6-second 4K: Omni Flash $2.25 on Sume, Veo 3.1 Fast $1.80 at Google

Six seconds at 4K costs $2.25 on Sume, because Gemini Omni Flash 1.1 at 4K is $0.375 per second, and it is the only 4K row in the Sume video list. On Google's pricing page, Veo 3.1 Standard at 4K is $0.60 per second ($3.60 for 6 s), Veo 3.1 Fast is $0.30 ($1.80), and Veo 3.1 Lite does not support 4K. Sume does not list Veo.

The 4K rows

Google rates are its list prices, read 2026-10-09, and assume the per-second rate applies to a 6-second request; check Veo's supported lengths on Google's side. The Sume rate is provider list times 1.25, so $0.375 / 1.25 = $0.30 implied list.

Where the 25 percent shows

The implied list for Omni at 4K is $0.30 per second, the same number Google lists for Veo 3.1 Fast at 4K. The price Sume charges is 25 percent above that, $0.375 against $0.30, which is $0.45 on a 6-second clip: $2.25 - $1.80. Against Veo 3.1 Standard, Sume's Omni 4K is 37.5 percent lower: ($0.60 - $0.375) / $0.60.

That comparison is on price only. Omni and Veo are different models, and this page makes no claim about their output quality.

Ten polished clips

A campaign of ten 6-second 4K clips costs $22.50 on Sume's Omni row, $18.00 at Google's list for Veo 3.1 Fast and $36.00 at Google's list for Veo 3.1 Standard. The cheaper workflow is to draft at lower tiers and finish only the clips you will publish: ten drafts at 720p are 10 x $0.75 = $7.50, plus three 4K finals at $2.25 each, or $6.75, for a total of $14.25.

That arithmetic holds only if a 720p draft predicts the 4K result, which is a prompt-by-prompt judgement. Check one draft against its final before you apply the plan to the whole set.

Aspect ratio is a constraint too: Omni on Sume takes 16:9 or 9:16 only, so a square 4K clip is not available from that row.

Budgeting 4K

Omni accepts 3 to 10 s in 16:9 or 9:16, so the 4K range is $1.125 to $3.75 per clip. The hold at submit is the full price, so a balance of $2.25 is just enough for one 6-second 4K clip and nothing else. A cheap path is to try the prompt at 360p ($0.0375 per second, $0.225 for 6 s) or 720p ($0.75 for 6 s), then render the keeper at 4K.
