Seedance 1.5 Pro
ByteDance's cinematic video model — smooth motion, first/last frame control, and reliable short-form clips.
About this model
Seedance 1.5 Pro is ByteDance's established short-form video model for text-to-video and image-to-video generation with smooth, cinematic motion. Its first/last-frame mode lets you anchor the opening and closing composition — ideal for ad storyboards where you already have hero stills from GPT Image 2 or Seedream on the same HiArt canvas. Clips run 4–12 seconds, long enough for social hooks and product demos without the complexity of multimodal reference pipelines.

FAQ
- Does Seedance 1.5 Pro generate audio?
- No. Seedance 1.5 Pro outputs silent video. Use Seedance 2.0 on HiArt when you need dialogue, ambient sound, or music generated in sync with the visuals.
- How do first and last frames work?
- Upload a starting image and an ending image. The model interpolates motion between them — useful when you already have key frames from an image model on the canvas.
