Keep the original scene, motion, and camera movement while intelligently replacing the person in a video, so anyone can become your video's star
Try: "Replace the person in this greeting video with the person from the reference image I uploaded, while keeping the original motion and background."


Upload the original video with the person you want to replace, along with a reference photo of the target person. Ribbi will automatically analyze the video content and find the best transition timing.
Ribbi accurately extracts key frames and seamlessly blends the person from the reference image into the original scene, while preserving composition, lighting, and shooting texture.
Using AI motion transfer, the new person faithfully reproduces all actions, expressions, and camera movement from the original video, generating the final video in one click.
Automatically analyzes motion beats, eye-line changes, and scene events in the video to pinpoint the best moment for character replacement, with no manual marking required.
Strictly keeps the original background, lighting, shadows, composition, and camera movement intact, replacing only the person to ensure natural, realistic results.
Intelligently analyzes the original subject's position, scale, and crop, then generates a new person that matches the original framing precisely to avoid visual mismatch.
With advanced motion transfer technology, the new person faithfully recreates every pose, expression, and movement from the original video while keeping the same duration and aspect ratio.
Supports iOS-shot .mov files and standard mp4 videos, with automatic conversion and processing so you don't need to adjust video settings manually.
Supports 2K high-definition generation while preserving the original shooting style, such as iPhone footage, for natural skin texture and realistic detail.
