Qu est-ce que Seedance 2.0 ?
Seedance 2.0 is ByteDance's flagship text-to-video model and one of the most flexible options on FlyAIgh — it generates clips anywhere from 4 to 15 seconds in seven aspect ratios (16:9, 9:16, 4:3, 1:1, 3:4, 21:9 and the model-adaptive 'adaptive' option that lets the AI pick).
The family ships in two variants. Seedance 2.0 Pro is the flagship at 10 credits per second — strongest motion coherence, best camera work, most expressive character animation. Seedance 2.0 Fast trims that to 9 credits per second with the same quality knobs (duration, aspect, resolution) for lower-cost iteration where the final polish isn't critical.
Both variants share four input modes: pure text-to-video, image-to-video (single first frame), first/last frame control, and reference-to-video — the standout capability where you supply up to nine reference images (subjects, props, locations) and Seedance composes them into a coherent scene. This makes Seedance the strongest pick when you have brand assets, hero products or returning characters that must appear unchanged across clips.
Native synchronized audio is included in every generation — dialogue, ambient sound, music. Output is 720p in seven aspect ratios.
Seedance is particularly strong at cinematic camera moves, stylized animation, and scenes that need multi-subject consistency. It is weaker than VEO 3.1 Quality for ultra-fine textural detail and weaker than Sora 2 Pro for photorealistic indoor lighting. Pick Seedance when reference fidelity and aspect-ratio flexibility matter more than per-pixel realism.
