Comparison
Seedance vs Veo 3 Fast
Seedance 2.5 is the control engine: up to 30 seconds, seeds, first/last frame, 1080p. Veo 3 Fast is the only engine that renders sound — room tone, effects, a line of dialogue — in fixed 8-second clips. The choice is usually made by whether the clip will be watched with the sound on.
