ComfyUI-RAFT integrates RAFT into ComfyUI to create motion brushes, enabling dynamic motion effects in user interfaces.
ComfyUI-RAFT is an extension designed to generate optical flow using the RAFT (Recurrent All Pairs Field Transforms) algorithm. Optical flow is a technique used to track the movement of objects between frames in a video or sequence of images. This extension can be particularly useful for AI artists who want to create smooth transitions, motion effects, or analyze the movement within their visual projects.
The main features of ComfyUI-RAFT include:
At its core, ComfyUI-RAFT uses the RAFT algorithm to compute optical flow. Optical flow refers to the pattern of apparent motion of objects in a visual scene, caused by the relative movement between the observer and the scene. RAFT achieves this by considering all pairs of pixels between two frames and iteratively refining the flow estimates.
Think of it like this: Imagine you have two consecutive frames of a video. RAFT looks at every pixel in the first frame and tries to find where that pixel has moved to in the second frame. It does this for all pixels, creating a "flow field" that shows the direction and speed of movement for each pixel.
The basic workflow of ComfyUI-RAFT involves loading your sequence of frames and running the RAFT algorithm to generate the optical flow. Here’s a visual representation of the workflow:

One of the features of ComfyUI-RAFT is the ability to save the generated motion data (referred to as MotionBrush) to disk. This allows you to reuse the motion data in other projects or for further analysis.

ComfyUI-RAFT utilizes different models to generate optical flow. These models are pre-trained and can be downloaded for use. Each model is designed to handle different types of scenes and motion characteristics. Here are some examples:
