SEEDANCE 2.5

Upload your files to Seedance 2.5 and write a clear prompt describing what you want. The AI automatically understands how to use your images for visual style, videos for motion reference, and audio for soundtrack. Just describe your vision in natural language - no complex tagging needed.

Direct generation caps at 30 seconds. But here's the trick - make a 5-second base clip, then extend it. Add 5 more seconds, then another 10 if you want. The extension feature keeps everything consistent (same character, same lighting) and you can chain them to hit 45, even 60 seconds. Just set your extension length to match how many new seconds you're adding.

No, it auto-generates sound. Footsteps, environment noise, basic audio that matches the scene. If you upload your own audio file, SeaArt AI uses that instead and syncs the visuals to it. The auto-generated audio works fine for previews but might need replacement for professional projects. You can also export silent and add audio later in post if needed.

Extremely accurate for clear movements (tracking, zooms, pans). Upload a reference video and Seedance 2.5 replicates the motion path reliably, enhanced by improved physics and prompt understanding. Combine with text for subtle adjustments.

First/Last Frame is useful when you want to animate between one or two images with a simple prompt. Full Reference gives you more creative control by combining images, video references, audio, and text prompts for more complex video generation.
