FAQs

What is Seedance 1.5 Pro?
Seedance 1.5 Pro is ByteDance's native audio-visual video generation model. It generates synchronized video and audio in one pass, including dialogue with multilingual lip-sync, optimized for ad creative and short-form drama.
How is Seedance 1.5 Pro different from Seedance 2.0?
1.5 Pro is the dedicated native audio-visual model with strong multilingual lip-sync and 10x-accelerated inference. 2.0 is the newer general-purpose flagship. Pick 1.5 Pro when dialogue and audio sync are the core of the brief.
Does Seedance 1.5 Pro generate audio?
Yes. Audio is generated jointly with the video, not added after. Dialogue, ambient sound, and timing are aligned at the millisecond level within the same forward pass.
What languages does the lip-sync support?
Seedance 1.5 Pro supports Chinese, English, Japanese, Korean, Spanish, and Indonesian, with native handling of regional accents including Sichuanese and Cantonese. Localized ad versions stay accurate per language rather than reading as dubbed.
How do I use Seedance 1.5 Pro on Morphic?
Open Copilot, describe the shot and the line of dialogue, and pick Seedance 1.5 Pro. For ad spots, dialogue-driven shorts, or any clip where audio and lip-sync are central, this is the right model over silent-video alternatives.
Can I pair Seedance 1.5 Pro with Seedream?
Yes. Generate a key still in Seedream or Seedream 4.5, then carry it into Seedance 1.5 Pro for image-to-video with synced audio, a clean end-to-end ByteDance pipeline on Morphic.
