Seedance 1.5 Pro is the mature, battle-tested member of ByteDance’s video lineup, prized for dependable prompt adherence and clean motion at a friendlier credit cost than the 2.0 flagship. Its standout spec is duration flexibility: 4, 8, or 12 seconds per generation, with the 12-second option giving room for a complete beat — setup, action, payoff — in a single render.
One page in the Create studio covers both of its workflows. Type a prompt for text-to-video, or attach up to two input images to steer an image-to-video generation. A fixed-lens switch locks the virtual camera in place for tripod-style shots — invaluable for product tables and talking scenes — and a generate-audio toggle adds sound to the render when you want it.
Where Seedance 1.5 Pro really separates itself is framing: eight aspect ratios, from 21:9 ultrawide through 3:2 and 2:3 photo formats down to 9:16 vertical, at 480p, 720p, or 1080p. If your deliverable list spans print-style crops and phone screens, this is the rare model that natively covers all of them.

Seedance 1.5 Pro questions, answered
What is Seedance 1.5 Pro?
Seedance 1.5 Pro is ByteDance’s mid-generation video model, generating 4-, 8-, or 12-second clips at up to 1080p from text or image input. It is available on Veo AI alongside the rest of the Seedance family, using the same credit balance.
How long are Seedance 1.5 Pro videos?
Generations run 4, 8, or 12 seconds. The 12-second ceiling is longer than most competing models offer in one pass, so many scenes that would normally require stitching can finish as a single render.
Does Seedance 1.5 Pro support image-to-video?
Yes. You can attach up to two input images and the model animates from them, keeping your subject’s look intact. Text-to-video works from a prompt alone on the same model page.
What does the fixed-lens option do?
Fixed lens locks the virtual camera so the framing never drifts during the clip — the AI equivalent of putting the camera on a tripod. Use it for product showcases, dialogue setups, or any shot where camera movement would distract.
Can Seedance 1.5 Pro add sound to a video?
It can, via an optional generate-audio toggle. Enable it and the clip renders with audio included; disable it for a silent, lower-cost pass. Sound is opt-in rather than produced by default.
Which aspect ratios does Seedance 1.5 Pro offer?
Eight in total: 16:9, 9:16, 1:1, 4:3, 3:4, 3:2, 2:3, and 21:9, each at 480p, 720p, or 1080p. That range covers widescreen, vertical, square, and photo-style crops without cropping in an editor afterward.
Seedance 1.5 Pro or Seedance 2.0 — how do I choose?
Go with 2.0 when you need 4K, 15-second clips, or nine-reference consistency. Choose 1.5 Pro for the 12-second duration at a lower credit cost, the eight-ratio framing menu, and the fixed-lens camera lock that 2.0 does not expose.
Do Seedance 1.5 Pro downloads have a watermark?
No — every video you render on Veo AI downloads clean at full quality, and new accounts receive free credits to test Seedance 1.5 Pro before choosing a plan on the pricing page.
How much does Seedance 1.5 Pro cost to use?
Generation runs on credits rather than a per-model subscription. The exact credit price of a render appears in the Create studio before you confirm it, and credits come from the plans and packs listed on the pricing page. Shorter, lower-resolution clips consume fewer credits.
Do I need a ByteDance account to use Seedance 1.5 Pro?
No. A single Veo AI account covers Seedance 1.5 Pro along with every other model on the platform, so there is no separate ByteDance signup, subscription, or API key to manage — one login and one credit balance handle everything.
