No prompt required
The model reads everything it needs from two files: the video supplies the motion and scene, the image supplies the new character. There is no text box to fill in, which makes it the quickest way to replace character in video.

Try Character ReplaceFAQ
No. Character Replace uses only your video and one image. There is no prompt field for this model.
One video in MP4, MOV or WebM up to 100 MB, and one image in JPG, PNG or WebP up to 10 MB.
It starts at 99 credits; higher resolution and longer clips cost more, and the exact cost is shown before you start. Failed generations are refunded automatically. New accounts get 50 free credits, and the Free plan adds 50 each month.
Content you generate can be used in ads, stores and social media, subject to NeoMundo's terms of service and the model provider's policies. Make sure you have the rights to both the source clip and the character image.
Use 480p for quick tests and 720p for final output. 580p sits between them when you want a sharper preview at a lower cost than 720p.
This usually comes from fast motion, heavy occlusion or a reference image that is cropped very differently from the video. Use a clip with one visible performer and an image that matches its framing.
Any character image works as the reference, including illustrated, animated and 3D characters. The performer in the clip should be a person or character with a clear body and face to follow.
Upload one video and one image, pick a resolution and see the credit cost before you generate. New accounts start with 50 free credits.

Head turns, hand gestures, dance steps and facial expressions from the original performer are reproduced on the new character frame by frame, so the timing of the clip stays the same.
The new character is lit to fit the original shot instead of looking pasted on, which is what separates character replacement from a simple overlay.
Choose 480p for fast, low-cost tests, 580p as a middle step, or 720p for the version you publish. Lower tiers use fewer credits.
At 99 starting credits it is the lowest-cost model in the Motion & swap studio, so you can try several character images on one clip before choosing a final look.
Wan 2.2 Animate is a video model from the Wan family developed by Alibaba. NeoMundo runs it in replace mode, listed in the studio as Character Replace: you give it an existing video and a single image of a character, and it swaps the performer in the clip for that character while keeping the original movement, facial expressions and scene lighting.
The idea is simple character replacement without a prompt. The source video acts as the motion track and the background plate; the image defines who should appear. Because nothing is described in text, results depend mostly on how well the two inputs fit together, which is why the tips on this page focus on choosing a good clip and a good reference image.
Inputs: exactly 1 video (MP4, MOV or WebM up to 100 MB) and exactly 1 image (JPG, PNG or WebP up to 10 MB). Output resolution: 480p, 580p or 720p. Pricing starts at 99 credits and rises with resolution and clip length; the studio shows the exact cost before you generate. Videos usually finish in about 1 to 5 minutes.
Choose Character Replace when you want a fast, prompt-free swap with one reference image. If you need up to 4 subject images, written instructions or 1080p output, Kling 3.0 Omni Video Swap in the same studio is the alternative; if you want to move a still character with borrowed motion rather than replace someone, try Motion Control.
Pick a video where one person is the obvious main subject, visible for most of the clip, with face and body not covered for long. Steady framing and even light make the swap more consistent.
Use a sharp image of the new character on a plain background. Match the framing of the video: a full-body image for a full-body dance, a waist-up image for a talking or presenting clip. Front-facing images with a neutral expression work well.
Start at 480p to check that the character reads correctly, then render the final version at 720p. The credit cost updates as you change the setting.
Run the job and check fast moves, turns and hands. If something drifts, try a clearer reference image or a shorter, steadier clip, then run the job again.
Film a dance or reaction yourself, then replace character in video with your brand mascot or illustrated character for social posts.
Reuse a trending dance or gesture clip and put your own character into it, keeping the original rhythm and moves.
Bring a 3D render, anime character or concept art into real motion by swapping it into acted reference footage.
Test how different characters or looks work in a scene you already shot before committing to a reshoot.
