Seedance 2.5 FAQ

Seedance 2.5 is billed by video tokens, exactly like ByteDance's official API: tokens = output seconds × width × height × 24 ÷ 1024. The tables above show the equivalent price per second at 16:9. With reference videos, the reference seconds are added to the output seconds and all of them are billed at a lower "with video input" rate. Audio is included at no extra cost and failed generations are never charged.
