Openjutsu: Local Character Swapping for Video on Consumer GPUs

X post0xMarioNawfalTool

Openjutsu replaces people in videos using a reference character photo, running locally on your own GPU. Camera motion, cuts, and audio stay intact, offering an open alternative to commercial services like Higgsfield.

Key points

  1. Replaces the main subject in a video using a reference character photo on local GPUs.
  2. Preserves original camera movements, cuts, motions, and audio tracks.
  3. Acts as a local, free alternative to paid cloud platforms like Higgsfield.
  4. Tested according to its README on an RTX 4060 Ti 16 GB paired with 64 GB system RAM.
  5. Community tests indicate a 17-second 768p render took roughly 28 minutes.

Why it matters

Local video-to-video AI workflows grant creators full control over data and costs, though local processing times remain demanding on consumer hardware.

Analysis

Openjutsu introduces a local workflow for character swapping in video, directly competing with paid SaaS tools such as Higgsfield. Users provide a source video along with a character still image, after which the model replaces the primary person while preserving motion, cuts, camera trajectory, and audio. Community feedback highlights the resource requirements of this pipeline. According to project documentation referenced by users, Openjutsu was tested on an RTX 4060 Ti 16 GB with 64 GB of RAM, relying on streaming H3 int8 models from system memory. This approach can be slow, with reported processing times around 28 minutes for a 17-second clip at 768p resolution. Community members also noted alternative local approaches, such as combining Minimax ref2va and dedicated LoRAs within ComfyUI.

Higgsfield charges for swapping the person in a video. This one runs free on your own GPU. Openjutsu: drop in a video and a photo of a character, press Generate, and the main person is replaced. The camera, cuts, motion and sound stay the same. It can also: → change someone's

  • @leuk_o @RoundtableSpace The Minimax character swap LoRA (linked below) is basically all you need with Minimax ref2va. Match the output resolution/length to the input video, and just tell it what you want swapped or changed (I use ComfyUI). t.co/TP2unz59px t.co/sUvFddWH4f
  • @Cozy2054934 @RoundtableSpace For anyone checking hardware: the README says it was tested on an RTX 4060 Ti 16 GB with 64 GB of system RAM, since the H3 int8 models stream from RAM. Not quick though, a 17s 768p face fix took about 28 min there.
  • @Cozy2054934 @Refiner_Studio @RoundtableSpace Glad it helped! If you try it, a short clip first is a good way to see how long renders take on your setup.
  • @LuckyPhelps @leuk_o @RoundtableSpace impressive. TY for the demo Mr Plains
  • @xatjc @RoundtableSpace How long does a minute of footage take on a normal GPU though? That's what decides if people use it over just paying Higgsfield
