How it works

Why 4D

You direct inside a 4D capture of the real scene: real scale, the real source camera path, the person's real motion and timing. The retake is driven by that geometry, and the pixels come from reshooting the real footage, so the person, place and motion stay theirs. LTX 2.3 renders every final frame. The capture is also a reusable asset, ready for video models that take 3D conditioning.

Inside ComfyUI

The workflow and the 4D camera editor, from video to final shot. Try the editor in your browser →

Camera keysKey the camera's position, aim and roll at any moment. Paths between keys run as smooth orbits or splines.
Camera view and editor viewLook through the shot camera, or press C to step outside and see the capture, the path and every key.
Blender-style view gizmoClick a dot for top, front or side, or drag it to orbit around the 4D capture.
A timeline built for shotsPlay, shuttle with J / K / L, step frames and jump between keys. Shift-select keys to move, rotate or retime them together.
PresetsStart from an arc, push, crane, orbit or bullet-time move, then edit the keys.
Portable camera pathsPaths export relative to the source camera, so a move made on one capture replays on another.

Results

Each example: the source video, then three new camera moves. The top view on each reshoot shows the path; the readouts show how far it moves.

Limitations

Example 4: source and two reshoots; the view through the window differs — **No fixed world.** There is no 3D world built and composited behind the person. Each reshoot regenerates what the source camera never saw, so off-camera objects can differ between angles. In Example 4 the view through the window changes.

Example 6: source and reshoot mid-spin; her face smears in the reshoot — **Fast motion smears.** Quick spins and fast arms can melt a face for a few frames. In Example 6 her face smears mid-spin.

Install

Set up Capture and its models on a CUDA machine.
Add Reshoot 4D to ComfyUI/custom_nodes/.
Install ReDirector and LTX 2.3, then restart ComfyUI.
