Motion Control makes an image copy the motion from a video — body motion, gestures, timing, and expression. The image can be a photo you own, including a selfie, or an illustration or stylized character. It is not Image to Video, which invents motion from a prompt, and it is not lip sync. ### How to use Motion Control Three steps. 1) Upload a photo: one JPEG, PNG, or WebP you own. Match a full-body photo with a full-body video, and a portrait with a portrait. 2) Upload a 3–30 second reference video. One subject in a continuous shot transfers more cleanly than cuts or a crowd. 3) Confirm credits, generate, inspect the private MP4, then download. Length follows the reference video. ### Is MixVio Motion Control free? An account is required. New accounts receive 40 welcome credits valid for 7 days. Motion Control is available on the Free plan when your balance covers the quote. The public route starts at 51 credits for 3 seconds at 720p. Failed runs cost no credits. ### How do credits work? Credits are billed by reference-video length: 17 credits per second at 720p and 23 credits per second at 1080p. A 3-second 720p run is 51 credits. The exact reservation appears before you generate. Failed or cancelled tasks release the reservation. ### What kinds of prompts work best? Leave the prompt empty, or describe scene, lighting, and camera only. Do not describe the action — the reference video already supplies it. Example: natural daylight, stable camera, keep the original location lighting. ### Will identity and fingers always stay perfect? No. Match framing and keep limbs visible. Hands, occlusion, and fast cuts can drift. Inspect the private export before you publish. This page does not include webcam capture or 4K. ### What if I am not satisfied with the result? Swap the photo or reference video, open Advanced settings to change camera, quality, or prompt, then generate again. Each new run shows its credit quote before submit. Failed runs cost no credits. ### Does Motion Control switch models? No. This page runs one Motion Control route and does not switch models. Use Image to Video when you want prompt-driven camera motion from an image instead of a reference video. ### What input limits apply? Upload one photo (JPEG, PNG, or WebP, up to 30 MB) and one reference video (MP4 or MOV, up to 50 MB). In Advanced settings, Follow video copies camera from the video for 3–30 seconds. Keep photo keeps the original framing for 3–10 seconds; describe lighting or camera in the optional prompt if you need a different shot. Keep original sound is on by default. ### What type of reference video works best? Use one clearly visible subject in a continuous shot. Match a full-body photo with a full-body video, and a portrait with a portrait. Smooth motion with little blur transfers more cleanly than cuts, a crowd, or a very different body orientation. Length follows the video. ### Can I use Motion Control outputs commercially? Paid-plan outputs may be used commercially, subject to the Terms of Service and the current provider terms. You must have rights to the photo, reference video, faces, brands, and any optional prompt. Free-plan outputs are for evaluation and are not for commercial publishing. ### Are uploads and results private? Yes. Inputs and outputs remain private workspace assets. Signed URLs, asset IDs, and private prompts are not added to public page URLs or analytics. ### Should I use Motion Control, Video to Video, or Image to Video? Use Motion Control when you already have a performance video to copy onto an image. Use Video to Video when you want to restyle or recast that video with an instruction. Use Image to Video when you want camera motion or action written in a prompt from an image. [Open Video to Video →](https://mixvio.ai/tools/video-to-video)
