In-store screen loop: a 30-second 16:9 clip at 720p vs 1080p on Sume

A 30-second 16:9 loop for a store screen costs $17.334 on Seedance 2.5 at 720p and $42.6465 at 1080p. On Wan 3.0 it costs $3.75 at 720p and $7.50 at 1080p. Both models accept up to 30 seconds.

A retail screen loop is an obvious use for a long clip, since a single take avoids cuts and joins in the file.

Price by length and resolution

Both clips and rates are on the public catalog. The Seedance numbers follow the token formula, ceil(width x height x seconds x 24 / 1024), at $0.0214 per 1,000 tokens at 720p and $0.0234 at 1080p, times 1.25. Wan 3.0 is a flat per-second rate.

Is 1080p worth it on a store screen

At 1080p Seedance 2.5 costs 2.46 times the 720p price for a 30-second clip. Wan 3.0 costs exactly 2 times. A screen near eye level shows more detail than a phone, so 1080p is a fair choice for a hero loop.

For a rotating set of promos, draft at 720p and render the one that wins at 1080p.

A weekly-refresh example

Four loops at 30 seconds, 1080p on Seedance 2.5 cost 4 x $42.6465 = $170.586. The same four at 720p on Wan 3.0 cost 4 x $3.75 = $15.00.

Each job holds its estimate at submit, so a 30-second 1080p Seedance clip reserves $42.6465 until it settles. See errors and credits.

Before you play it

• Test the loop on the real screen; players may crop or scale.
• Check that on-screen prices and dates are correct in every frame.
• Keep a copy of the prompt with the file so a later refresh matches.
