Video Editing cover image

Edit existing videos by replacing characters, adjusting scenes, or adding and removing elements. How it works: select a region in your video (a character, an object, or a background area) and describe the change you want. The model inpaints the selected area while preserving the rest of the frame — motion, lighting, and temporal consistency are maintained across the edited section. Operations include character replacement, object removal, element addition, and background extension. When to use this: a finished ad where the brand ambassador changed and the person needs to be swapped without reshooting; product footage where an unwanted object is in frame; a scene where the background needs to be extended for a wider aspect ratio; post-production fixes to existing brand or entertainment footage. Tips and practical notes: the cleaner the selection boundary, the better the inpainting result. For character replacement, provide a reference image of the new character to guide appearance. The model handles motion continuity in the edited region, but complex interactions (two characters physically touching) may need more careful prompting. For best results, edit one element at a time rather than making multiple changes in a single pass.

Frequently asked questions

What can I edit with Seedance 2.0 video editing?

You can perform inpainting, character replacement, background extension, and add or remove elements on AI-generated or live-action footage without rebuilding the entire clip.

Do I need to reshoot after editing?

Not necessarily. The capability is intended to adjust footage that already exists, such as swapping a person, changing a scene, or adding elements.

Can I replace a character while keeping the original scene?

Yes. Provide a reference image of the new character and select the person to replace. The model swaps the character while preserving the scene's lighting, motion, and surrounding elements.

Does video editing work on live-action footage?

Yes. Both AI-generated and live-action footage can be edited. The model maintains temporal consistency across frames, so edits blend naturally with the existing footage.
