Seedance 2.0 KI-Videogenerierung

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 three variants. Seedance 2.0 Pro is the flagship at 11.1 credits per second (at 720p) — strongest motion coherence, best camera work, most expressive character animation, and the only variant that renders past 1080p. Seedance 2.0 Fast trims that to 8.9 credits per second at 720p for lower-cost iteration where the final polish isn't critical. Seedance 2.0 Mini drops to 5.6 credits per second at 720p — the budget entry that keeps the full multimodal reference stack (up to nine images, three videos, three audio tracks) but has no first/last-frame slots, so it offers text-to-video and reference-to-video only.

Pro and Fast share four input modes: pure text-to-video, image-to-video (single first frame), first/last frame control, and multimodal reference-to-video — the standout capability where you supply not just images but reference videos and audio (up to nine images, three videos and three audio tracks) and Seedance composes them into a coherent new scene that follows your prompt. Images can fix a character, product or style; a reference video can carry a look or camera move; reference audio can drive the soundtrack. This is what powers FlyAIgh's video-to-video workflow, and makes Seedance the strongest pick when brand assets, hero products or returning characters must appear unchanged across clips.

Native synchronized audio is included in every generation — dialogue, ambient sound, music. Resolution pricing follows real render cost rather than a flat multiplier: Seedance 2.0 Pro spans seven tiers from 480p (half the 720p rate) up through 1080p, a premium native-1080p render, 2K, 4K and a premium native-4K render (5x the 720p rate — the most expensive single tier on FlyAIgh, reserved for true native 4K capture rather than upscaled 4K). Fast is simpler, with five tiers from 480p through 2K and 4K and no native-resolution renders; Mini mirrors those five tiers at roughly half the Pro rate.

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.
