Seedance 2.5 price by aspect ratio: 9:16 vs 16:9 vs 21:9 on Sume
At 720p a 5-second Seedance 2.5 clip is $2.889 at 9:16, 16:9 and 1:1, $2.903 at 21:9 and $2.907 at 4:3. Aspect ratio barely moves the price.
A vertical 9:16 Seedance 2.5 clip costs the same as a 16:9 one on Sume: $2.889 for 5 seconds at 720p. Ultra-wide 21:9 is $2.903 and 4:3 or 3:4 is $2.907, a difference under 1 percent. Price follows output pixels, and each ratio has a fixed pixel size that lands close to the same area.
Why the price is flat
fal's Seedance 2.5 page lists these output sizes: 480p at 992x432 (21:9), 864x496 (16:9), 752x560 (4:3), 640x640 (1:1), 560x752 (3:4), 496x864 (9:16); and 720p at 1470x630, 1280x720, 1112x834, 960x960, 834x1112 and 720x1280. Tokens are width x height x seconds x 24 / 1024, so the cost depends on area, not shape.
