VIDEO EDITING GUIDE
AI Video Character Swap
Replace a person in a video with a reference character while keeping the original performance, motion and camera movement.
Create VideoReplace appearance while keeping the action
Video character swapping uses an existing performance as the basis for a different on-screen character. The source clip establishes movement and camera pacing; a reference image defines the desired appearance. This differs from generating a new video from a portrait because you already have a shot whose timing matters. AI Genjutsu’s current editor connects this workflow with selectable 480p, 720p or 1080p output. Treat motion preservation as the goal and inspect the output for drift. A successful change should look coherent during movement, not merely resemble the reference in a paused frame.
Pick footage with one clear target
Choose a clip with a visible subject and one continuous action. A person walking, turning or making a readable gesture is a better first test than a montage with multiple cuts. Trim the source to four seconds for an initial assessment. The editor accepts supported MP4 or MOV video, validates media constraints and shows a quote based on the actual duration. Check the upload guidance for size, frame-rate and dimension limits. If someone repeatedly disappears behind other people or objects, expect a more demanding continuity problem.
Prepare a useful reference
Use a reference character that is clear enough to communicate face, hair and visible clothing. Similar framing can help: a full-body performer is easier to describe with a reference that includes more than a tiny cropped face. Avoid an image containing several equally prominent people when the edit requires one character. Choose footage and imagery you have permission to use, including permission from identifiable people where needed. A reference is a visual guide rather than a guarantee of exact identity reproduction across every angle in a moving shot.
Write a focused replacement instruction
Identify the target by position or clothing, then explain what to retain. For example: replace the center performer in the white shirt with the reference character; keep the dance timing, body movements, stage and camera track. Do not ask for a new dance and preservation of the original dance simultaneously. Changing identity, environment and camera style together makes the result harder to evaluate. Start with one replacement, then consider another version once you know which elements already work. Our prompt guide includes templates you can adapt to your source.
Review and download the completed edit
Sign in, upload both materials, describe the change and request the credit quote. Confirm the amount before generating. Follow the existing task’s status and use history to return to it rather than creating duplicate requests. When the video is ready, compare the source and result from beginning to end. Look for face consistency, body proportions, fingers, occlusion and camera pacing. Download the completed edit for further assembly. AI character editing can accelerate influencer concepts, social clips and creative previews, but output still needs your review before publication or client delivery.
Finish the clip deliberately
After reviewing the edit, use your normal video workflow to assemble the final piece. Check the exported frame rate, crop and visual quality before adding captions or distributing it. Do not assume that changing a character grants rights to the underlying footage, soundtrack or reference image. A short proof of concept should answer whether the appearance and performance work together. Keep the source alongside the downloaded output so you can identify which details changed and decide whether another paid attempt is worthwhile.
Frequently asked questions
Can I replace a person in a video?
That is the current connected workflow. Start with a clearly visible subject and a reference character.
Does it preserve motion exactly?
Motion and camera preservation are goals, but frame-perfect results are not guaranteed.
Which quality is available?
The current editing workflow offers 480p, 720p and 1080p output.
