Wan VACE is presented in Cleep as a prompt-guided video editing option. Instead of generating an unrelated shot from scratch, an editing workflow begins with source footage and a specific change to make. The clearest results come from defining what must change, what must remain untouched, and how the edit should behave across the full duration of the clip.
Use a short, stable clip with a clearly visible subject and enough resolution to inspect the result. Keep the original file, note its frame rate and aspect ratio, and trim away sections that are not part of the intended edit. Heavy compression, rapid cuts, motion blur, occlusion, and very small details can make temporal consistency harder to evaluate.
Before uploading, identify protected details: a face, product shape, logo, garment, background area, or camera movement. Your prompt can then distinguish the target edit from elements that should be preserved.
A global instruction changes the overall look, such as atmosphere, palette, or style. A local instruction targets a particular subject or region. Local work benefits from an unambiguous target and strong visual separation from the background. When a change crosses several textures or is repeatedly occluded, divide the task into simpler passes where possible.
Do not judge an edited video by one still frame. Watch for flicker, drifting edges, changing identity, unstable textures, new objects, altered text, and inconsistencies when the target leaves and re-enters the frame. Compare the edited clip side by side with the original and inspect the beginning, the most difficult motion, and the final frames.
For production, save the source, instruction, settings, and result as one versioned set. If an edit must be approved by a client or editor, include notes describing which changes are intentional and which details were checked manually.
Edit only footage you own or are authorized to modify. Removing ownership marks, changing a person’s actions, or altering documentary material may create legal or ethical problems. Preserve provenance and disclose synthetic changes whenever an audience could mistake the result for an authentic recording.
Begin with the most important change. Several local and global edits at once make it harder to identify the source of an artifact.
Fast motion, occlusion, compression, weak target separation, or a broad instruction can reduce consistency. Try a shorter section and a more specific target.
Keep the unedited source, exact instruction, chosen options, output, and review notes. This makes a later version easier to reproduce.
