Draft at 480p, finish at 1080p: a Wan 3.0 holiday loop for $22.10

Thirty 5-second drafts at 480p cost $9.60 on Wan 3.0 through Sume, and five 10-second finals at 1080p cost $12.50, for $22.10 in all. Rendering 30 clips straight at 1080p would cost $37.50, so the draft loop saves $15.40 and gives you six times the ideas per finished ad.

Wan 3.0 suits this loop because one model id covers all three resolutions and every length from 2 to 30 seconds, so the prompt you approve in a draft is the prompt you re-render.

Prices used

The Video Router catalog lists Wan 3.0 at $0.05, $0.10 and $0.20 per second for 480p, 720p and 1080p (fal 2026-08-24). Sume bills list × 1.25: $0.0625, $0.125 and $0.25 per second. A 5-second 480p draft is $0.3125, billed as $0.32. A 5-second 1080p clip is $1.25, and a 10-second 1080p final is $2.50.

Why the draft count is thirty

Holiday creative fatigues quickly, and the winning hook is rarely the one you expected. Thirty drafts let you test six hooks across five product angles. Because a draft costs under a third of a dollar, rejecting 25 of them costs $8.00, which is about the price of three 1080p finals.

The part that needs care

A draft at 480p is not a preview of a final at 1080p in every respect. Fine text on packaging, thin fabric patterns and fast motion can look acceptable at 480p and fail at 1080p. So judge drafts on composition, hook and pacing, never on label legibility, and leave a retry line for finals: 2 extra finals add $5.00, which brings the plan to $27.10.

Also note that the finals here are 10 seconds, double the draft length. If a hook lands in a 5-second draft, extending it needs a prompt that says what happens in the second half. Write that before you render.
