Video to Video AI is a tool that transforms short video clips by applying new visual styles while preserving the original motion and framing. You upload a 2-15 second MP4 or MOV (up to 50 MB, with a minimum short edge of 480 pixels), describe what you want to change, and the system generates a new version at 720p or 1080p. The key limitation: it's generative, not precise. Faces, details, timing, and framing can shift. You get one focused change per request—asking for multiple unrelated edits makes results harder to evaluate. The tool handles style transfers (anime, 3D, watercolor, comic, pixel, cinematic), background swaps, character replacements, and motion transfers where you provide a reference image to guide appearance while the original clip dictates the movement. The workflow is iterative. You preview each result privately, compare it against the source, download the MP4, and refine from there. Earlier versions stay in your history. You can adjust output duration (5, 10, or 15 seconds), aspect ratio (16:9, 9:16, 1:1, 4:3, 3:4, 21:9, or auto), and optionally generate new audio—though generated audio replaces the source rather than preserving it. For character work, you need both a movement video and a clear character reference image (up to 10 MB). The system uses your original footage to guide timing and camera flow while your prompt directs the visual treatment. Success depends on input quality and prompt clarity. Use stable framing, readable action, and a clear subject. Start with one coherent direction rather than piling on requests. For background changes, specify the setting, time of day, and light while identifying what stays recognizable. For style transfers, name the look first, then layer in details about subject, scene, and palette. There's no exact match guarantee—the model interprets both source and prompt independently, so treat each output as a variation to review and potentially iterate on rather than a guaranteed transformation.
