Seedance 1 Pro
ByteDance's precision video model. Generate 1080p video in 6 aspect ratios with both start and end frame control — ideal for directed transitions, reveals, and precise before-and-after content.
What is Seedance 1 Pro?
Seedance 1 Pro is ByteDance's precision-focused video generation model. Its defining capability is full start and end frame control — you provide an image for the first frame and an image for the last frame, and the model generates a 1080p video that begins at one and ends at the other.
The combination of dual-frame control with 6 aspect ratio support makes it versatile for before-and-after content, transition videos, and any directed motion where both the opening and closing visual need to be specific. At 1080p across portrait, landscape, and square formats, the output is suitable for professional content delivery across platforms.
For content creators working in e-commerce, fashion, beauty, and lifestyle — categories where visual transformation is a core storytelling device — Seedance 1 Pro's dual-frame control is a particularly powerful tool.

How to generate video with Seedance 1 Pro on project.video
Open the composer
Go to your project.video dashboard and open the generation composer. Seedance 1 Pro is available under ByteDance models.
Select Seedance 1 Pro
Choose Seedance 1 Pro when you need dual-frame control. The composer will show the start frame and end frame upload slots.
Upload both frames
Upload your start image (the opening visual state) and your end image (the closing visual state). Together, these define the full visual arc of the clip.
Set specs and generate
Choose your aspect ratio from 6 options and write a prompt describing the desired motion and style. Hit generate for a 1080p clip that bridges your two frames.

Best use cases
Beauty before-and-after
Supply a 'before' shot (skin texture, makeup-free, natural hair) and an 'after' shot (finished look, styled). Seedance 1 Pro generates a smooth visual transition between them — ideal for beauty brand content.
E-commerce product transformation
From raw material to finished product, from flat-lay to styled shot, from plain packaging to gift-wrapped. Dual-frame control makes product transformation videos precise and controllable.
Lifestyle scene transitions
Morning to night, indoor to outdoor, one outfit to another. At 6 aspect ratios and 1080p, Seedance 1 Pro handles lifestyle content transitions for every platform format.
Motion graphics transitions for video editing
Generate AI-driven transitions between two specific visual states for use in edited video projects. Both frames are precise, so the transition clips are drop-in ready for edit timelines.
