Features

Wan 2.7 Video Edit

Wan 2.7 Video Edit performs prompt-driven editing on existing videos with optional multi-image reference support. Upload a source video, describe the desired edits in natural language, and optionally provide reference images to guide the target style or element appearance — the model applies precise, context-aware edits while preserving motion and temporal consistency throughout the clip.

• Need to generate from an image? Try Wan 2.7 Image-to-Video

Why Choose This?

• Natural-language video editing Describe your edit in plain text — swap colors, change objects, alter styles — without manual masking or keyframing.

• Multi-image reference support Upload 1 to 9 reference images to guide the target element, style, or appearance in the edited output.

• Audio control Choose between auto mode (model decides) or origin to preserve the original audio track.

• Negative prompt support Specify what to avoid in the edit for more precise control over the output.

• Prompt expansion Enable enable_prompt_expansion to let the model automatically enrich and optimize your prompt before generation.

• Resolution options Generate at 720p or 1080p to match your delivery requirements.

Parameters

How to Use

1. Upload your video — provide the source clip to edit via URL or drag-and-drop.
2. Write your prompt — describe exactly what should change (e.g., “Change the motorcycle’s color to blue.”).
3. Add reference images (optional) — upload images to guide the look of elements or styles in the edit.
4. Add negative prompt (optional) — specify elements you want to exclude from the output.
5. Select resolution — 720p for standard output, 1080p for higher-quality results.
6. Set duration (optional) — leave at 0 to match the input video length, or set 2–10 to trim.
7. Set audio_setting (optional) — choose auto or origin to preserve original audio.
8. Enable prompt expansion (optional) — let the model automatically enrich your prompt.
9. Set seed (optional) — fix the seed to reproduce a specific result in future runs.
10. Submit — generate, preview, and download your edited video.
