Wan 3.0 bumper prices: 2 to 6 seconds at 480p, 720p, 1080p

A 2-second Wan 3.0 bumper costs $0.125 at 480p, $0.25 at 720p and $0.50 at 1080p on Sume. A 6-second bumper costs $0.375, $0.75 and $1.50. Wan 3.0 accepts 2 to 30 seconds, so short bumpers are legal; the price is rate times seconds.

The ladder

Alibaba Cloud lists Wan 3.0 at $0.05, $0.10 and $0.20 per second by output resolution (read 2026-10-07). Sume bills list times 1.25, giving $0.0625, $0.125 and $0.25.

Picking a bumper length

Short bumpers are often reused, so a single good one is worth more than a cheap batch. At 720p, ten different 4-second bumpers cost $5.00; one 4-second bumper at 1080p costs $1.00.

Seconds are the only quantity that grows linearly, so doubling the length doubles the price at every resolution. Going from 480p to 1080p is a fourfold increase at the same length.

• Start at 480p to check motion and framing.
• Re-render the approved bumper at 720p or 1080p.
• Keep the approved clip and reuse it instead of regenerating.

Buying bumpers in a batch

Twenty 4-second bumpers at 720p cost $10.00. At 480p they cost $5.00, and at 1080p $20.00.

A batch like that is a good test of queue behavior. On the Free plan one job processes at a time and five more can queue, so six jobs are accepted; a seventh returns 429 queue_full until one finishes or you cancel a queued job. Pro accepts 24, Startup 48 and Scale 120. Each queued job holds its reserve, so twenty bumpers at 720p hold $10.00 until they run.

If a bumper fails, Sume refunds the hold. If you cancel before generation starts, the hold is released as well; once generation has started, cancel returns 409 and the job runs to its end.

Bumper price against a full ad

A bumper is a fraction of a 15-second ad. At 720p, a 6-second bumper at $0.75 is 40 percent of the $1.875 cost of a 15-second ad, because both bill by the same per-second rate.

That makes the choice of length a pure cost decision. A 2-second sting at 720p is $0.25, so you can generate a dozen variants for $3.00 and keep the best one.

The same per-second logic holds for the ceiling. Wan 3.0 accepts up to 30 seconds, and a 30-second clip at 480p is $1.875, at 720p $3.75 and at 1080p $7.50. Bumpers sit at the bottom of the same ladder.

Native audio and sound

Budget the sound separately. A bumper that needs music or a voice line adds a Lyria bed at $0.125 flat or TTS at $0.0475 per 1,000 characters, and a short voice line of 60 characters costs $0.0028. Those lines are small beside a 1080p bumper at $1.50, and they change the total only when you make hundreds.

Where it fits

For a three-second hook, Omni Flash 1.1 at 360p is the cheaper floor at $0.1125, but it stops at 10 seconds, while Wan 3.0 runs to 30. The Wan and Omni comparison shows where their 720p prices meet, and the $20 table scales these figures to a wallet.
