Multimodal References & Region Editing

v2.0.0

Major update adding up to 50 multimodal references, region-level editing, near real-time generation, and new aspect ratios

New Features

  • Up to 50 Multimodal References: Guide a generation with as many as 50 images, video clips, and audio references at once for tighter control over character, style, and motion
  • Region-Level Editing: Re-render just one region of a shot instead of the whole clip — fix a hand, swap a background, or refine a detail without regenerating everything
  • Near Real-Time Generation: Dramatically faster turnaround so you can iterate on ideas almost as fast as you can type them
  • New Aspect Ratios: Added ultra-wide 21:9 and vertical 9:16, on top of the existing 1:1, 3:4, 4:3, and 16:9

Improvements

  • +20% Prompt Adherence: Upgraded to Seedance 2.5, which follows your prompt roughly 20% more closely than the previous generation
  • Reference manager for organizing and reusing your multimodal inputs
  • Sharper motion consistency across the full 30-second clip

Bug Fixes

  • Fixed reference weighting when mixing image and audio inputs
  • Resolved an edge case where region edits could shift adjacent pixels
  • Improved stability of near real-time previews under heavy load

Seedance2Pro Launch

v1.0.0

First public release of the Seedance 2.5 video studio — 30-second Text-to-Video and Image-to-Video with native audio

Core Features

We're thrilled to launch Seedance2Pro, the studio built around ByteDance's Seedance 2.5 model. This first release brings native-length generation to everyone:

  • 30-Second Text-to-Video: Describe a scene and generate a full 30-second clip in a single pass — consistent from the first frame to the last, no stitching required
  • Image-to-Video: Turn a still image into motion while keeping your subject and composition stable across the whole shot
  • Native Audio Sync: Sound and picture are produced in the same latent pass, so dialogue, effects, and ambience land in sync out of the box
  • Aspect Ratio Presets: Generate in 1:1, 3:4, 4:3, and 16:9 to fit social, portrait, and widescreen formats

Plans & Credits

  • Free: Try Seedance 2.5 with a starter batch of credits
  • Pro: A larger monthly credit allowance for regular creators
  • Studio: The highest credit tier for teams and heavy production work

Improvements

  • Credit-based generation with a clear cost shown before every render
  • Faster queueing so your first clip starts generating sooner
  • Optimized playback and download across mobile and desktop

Bug Fixes

  • Fixed occasional audio drift on longer clips
  • Resolved a rendering glitch on portrait aspect ratios
  • Improved error messages when a prompt is rejected
