Genjutsu AI Video Editor - Transform Videos with AI

What

Genjutsu AI Video Editor is an independent video-to-video AI editing service that transforms existing footage by replacing the main visible person with a reference character while following the source performance. It is positioned for creators, professionals, and power users who want to reuse short clips with a new on-screen character without manual masking, timeline editing, or frame-by-frame replacement. The current workflow starts with character replacement rather than a separate full motion-transfer mode.

Features

• Character replacement in existing video: Upload a source video and a reference character image; the service recreates the character while using the original motion, timing, camera movement, and background as guides.
• Source-performance preservation: The source video guides body movement, shot timing, and camera path; results can vary depending on motion, occlusion, source quality, and the reference image.
• Pre-generation validation and cost check: Before generation, files are uploaded and validated and the cost is calculated; this check does not generate video or consume generation credits.
• Input and output controls: The site accepts H.264 MP4/MOV up to 20MB and PNG/JPEG/WebP up to 8MB, with 480p, 720p, and 1080p output options. Listed API requirements include 4–30 seconds, 24–60 FPS, each side 300–6000px, width/height ratio 0.4–2.5, and video frame pixels 409,600–8,295,044.
• Credit-based access: Video generation requires credits because AI video processing has significant compute costs; users can buy credits separately or choose monthly or yearly subscriptions.

Helpful Tips

• Start with short, continuous clips featuring one clearly visible subject; heavy occlusion, rapid cuts, and multiple overlapping people can make consistency more difficult.
• Use a clear reference image where the character’s face, hair, and overall appearance are easy to see; similar framing to the source subject can also help.
• Review the estimated generation cost before proceeding. Credits are required for generation, and the pricing section states site credits are returned on confirmed failures.
• If avoiding a subscription commitment, buying credits separately is supported. Monthly and yearly plans are available for casual, professional, and power-user tiers. Since the service is independent and not affiliated with or endorsed by Higgsfield, verify fit and terms independently.
