Model overview

Seedance 2.5 Unrestricted video generation

Seedance 2.5 Unrestricted creates videos from a written description or a source image with fewer creative restrictions. A text prompt can define the subject, setting, action, visual style, camera movement, lighting, pacing, and sound. When a first-frame image is supplied, the model animates that composition and preserves its aspect ratio.

For more directed transitions, provide both first and last frames. The model uses them as visual anchors for the beginning and end of the shot while generating the movement between them. Clips can run from 4 to 30 seconds at 480p or 720p, with synchronized audio available as an optional part of the same generation.

What you can create

Cinematic scenes generated entirely from a detailed text prompt
Product, character, landscape, and editorial images animated into video
Controlled visual transitions guided by opening and closing frames
Landscape, portrait, square, classic, and ultrawide social formats
Silent clips or videos with synchronized ambience and sound effects
Quick 480p drafts followed by more detailed 720p final generations

Video output

Each successful request returns a generated video ready to preview and download. MP4 is the broadly compatible default. MOV can be used in workflows that benefit from higher color precision for grading, keying, or compositing.

MP4

Recommended for browsers, social platforms, and general playback.

MOV

Useful for compatible professional editing and post-production workflows.

Model inputs

Controls for every shot

Use only a prompt for text-to-video, add one image for image-to-video, or provide first and last frames for a directed transition.

Prompt

Describe the scene, subject, action, camera movement, lighting, and sound.

First frame

An optional JPG, PNG, or WebP image used as the opening frame.

Last frame

An optional closing image. Add a first frame when using this control.

Resolution

Choose 480p for quick drafts or 720p for more detail.

Aspect ratio

Adaptive, 16:9, 4:3, 1:1, 3:4, 9:16, and 21:9 are supported.

Duration

Select any whole-second duration from 4 to 30 seconds.

Audio

Turn synchronized audio generation on or off for each request.

Output format

Choose broadly compatible MP4 or MOV for compatible post-production workflows.

Best results

Describe subject movement and camera movement separately.
Include lighting, lens, framing, and pacing when they matter.
Use a first frame when visual identity and composition must stay consistent.
Use first and last frames when the destination of the shot is important.

Flexible duration and format

Generate short social clips or longer scenes from 4 to 30 seconds. Select landscape, portrait, square, classic, or ultrawide framing before generation.
