Overview
Seedance 1.0 Lite is the budget-friendly entry in ByteDance's Seedance family, released in June 2025. It targets rapid prototyping and high-volume workflows where cost and turnaround matter more than peak fidelity. The model supports both text-to-video and image-to-video at resolutions from 480p to 1080p, with fixed 5- or 10-second durations. There is no audio generation — output is video only.
Use cases
Social media shorts and quick-turnaround content. Storyboard previews and concept validation before committing to a higher-tier model. Batch generation for A/B testing thumbnails or ad creatives. Image-to-video conversion for animating product stills or illustrations.
Inputs
All parameters are passed in the input object of the run request.

Prompt tips
Front-load the subject and action
Lite works best with clear, direct descriptions. Put the main subject and its action in the first sentence — "A cat leaping off a shelf" outperforms "In a cozy room, there is a cat that eventually jumps."
Stick to single scenes
With only 5- or 10-second clips and no multi-shot support, focus each prompt on one continuous action rather than describing a sequence of events.
Limitations
- No audio generation — video output is silent
- Only two duration options (5s or 10s)
- Lower visual fidelity compared to the Pro variant at the same resolution
- Aspect ratio is ignored when using image-to-video (derived from the source image)
- Prompt minimum is 1 character, but very short prompts produce unpredictable results
FAQ
How does Lite compare to Seedance 1.0 Pro?
Lite costs less per generation and supports 480p (which Pro does not), but produces lower-fidelity output. Pro offers sharper detail and handles multi-shot transitions better.
Can I use image-to-video with Lite?
Yes. Provide a single image via image_urls and the model animates from that frame. When an image is provided, the aspect ratio is derived from the source image rather than the aspect_ratio parameter.
Does it support audio?
No. Audio generation was introduced in Seedance 1.5 Pro. Use that model or Seedance 2.0 if you need sound.
