Seedance 1.5 Pro - Native Audio-Visual Sync, Broadcast Quality

Does Seedance sync audio and video during generation, or do I need to fix it in post-production?

Seedance generates audio and video simultaneously using a dual-branch Diffusion Transformer, so the sync is native to the output. You do not need post-production sync work; the video arrives in sync with the audio.

Can Seedance generate lip-sync for languages other than English?

Yes. Seedance handles multilingual and dialect-specific lip-syncing, so you can create videos in regional variants without separate voiceover records or manual adjustment.

What cinematic controls does Seedance offer for camera movement and framing?

Seedance includes dynamic cinematic camera control, which means you can direct things like camera angles, movement, and composition during generation rather than accepting a single default output. The specifics of which parameters you can control are not published on their site, so contact them for technical detail before committing to a workflow.

How much faster is Seedance 1.5 Pro than the previous generation?

Seedance claims 10× faster inference speeds compared to its predecessor, which matters if you are running high-volume production workflows. At professional scale, that speed difference compounds across hundreds of videos.
