Make videos with ByteDance's Seedance 2.5 Flash or Seedance 2.5. Start from a prompt or an image, guide the shot with up to 20 references on Seedance 2.5 Flash (50 on Seedance 2.5), or edit a video you already have.
Seedance Flash, full name Seedance 2.5 Flash, is the accelerated version of ByteDance's Seedance 2.5 video model, released in November 2026. It makes videos of 4 to 30 seconds at 480p or 720p and is built for quick previews and frequent revisions.
Seedance Flash runs in the browser on desktop and mobile, with nothing to install. It offers four modes: text to video, image to video with a start and last frame, reference to video with images, videos and audio, and editing of a video you already have.
The Seedance model family
The generation that brought image, video and audio references and multi-shot scenes.
Raised one take to 30 seconds and references to 50, for higher-quality finals.
The accelerated version of Seedance 2.5: faster generation for quick previews and frequent revisions.
Seedance Flash suits short videos you want to try and revise quickly: social clips, product ads, storyboard tests and scenes up to 30 seconds.
Seedance 2.5 Flash makes one continuous clip of 4 to 30 seconds, with no cuts or stitching. For a long take, split the prompt into time ranges (for example 0-6 s, 6-12 s) and give each range one action. Keep to one location and one steady camera path so a 30-second take stays on track.
Seedance Flash turns a text prompt into a video, with no images needed. Write the subject, the action, the camera move and the sound in plain sentences. Crowding one shot with many people and actions tends to muddle the picture.
Upload a start frame and Seedance Flash animates it, keeping the face, clothes and light of the photo. Add an end frame to set where the clip finishes. If the two frames show different people or places, the move between them looks forced.
Seedance 2.5 Flash takes up to 20 references in one video: 10 images, 5 videos and 5 audio clips. Tag each one in the prompt (@Image 1, @Image 2) and say what it is for, such as a face, an outfit or a setting. Seedance 2.5 takes up to 50 references.
One prompt can give Seedance Flash several shots in a single video. Write one shot per line and start each new shot with "Cut to". Add a character image as a reference to keep the same person in every shot.
Seedance 2.5 Flash edits a video you already have: upload a clip of 4 to 30 seconds and describe the change in words. Say what should change and what should stay, such as an object's material or the camera move. Editing is billed per second of the source video.
Use Seedance 2.5 Flash for drafts and quick clips of up to 30 seconds at 480p or 720p. Use Seedance 2.5 for higher-quality finals at up to 1080p. Use Seedance 2.0 for short clips of up to 15 seconds in 4K.
