Wan 2.1 VACE Video Edit

Wan 2.1 VACE Video Edit is the Wan 2.1 workflow for source-video transformation. It models visual appearance and time together so the route’s written direction, source imagery, speech, masks, or structural conditions influence one coherent result rather than a collection of disconnected frames or a generic endpoint response.

Choose this exact route when the available assets and deliverable specifically call for source-video transformation. Identify every subject and source, state the desired action or transformation, then describe camera behavior, pacing, environment, lighting, atmosphere, and preservation requirements; local schema fields handle resolution, duration, seed, and delivery separately from the creative brief.

Highlights

• 2.1 Temporal source editing. Changes an existing clip while retaining its timeline and scene foundation.
• 2.1 Cross-frame edit consistency. Applies the transformation coherently instead of independently per frame.
• 2.1 Semantic scene revision. Changes objects, style, environment, or presentation through written direction.
• 2.1 Motion and identity preservation. Retains important subject movement and recognizable content where requested.
