ComfyUI-FrameSkipping Component Introduction

中文 | ENGLISH

Question: Why was this component developed?

Answer: The primary motivation for developing this component was to create a video where the texture of a hand changes upon touching an object. To achieve this gradient effect, I developed this component to allow for precise splitting of a video, rather than simply dividing it into two segments.

This plugin enables precise control over frame-to-frame rendering, allowing for the composition of multiple frames in a single load.

The node group is named: baicai

The ComfyUI workflow will be uploaded in the future.

Developed Features

Frame Selector

• Frame Selector: By inputting the start frame and end frame, it selects the frames in between. If extension frames are needed, any number of frames can be added.
  • Development Reason: Although similar results could be achieved with the previous node using IntOperationsNode, it was cumbersome. Therefore, a single node was developed to simplify the process.

Mask Selector

• Mask Frame Selector: Obtain intermediate frames by inputting the start and end frames. Additional frames can be added if continuation is needed.
  • Reason for Development: The mask and image need to be synchronized to avoid errors.

Frame Truncating

• Frame Truncating: Retains only the first n frames.
  • Development Reason: To achieve the desired animation effect, the first 16 frames need to be processed separately from the subsequent frames.

Frame Skipping

• Frame Skipping: Skips the first n frames.
  • Development Reason: To avoid animation overlap, the first 16 frames need to be skipped.

Mask Frame Skipping

• Mask Frame Skipping: Skips the first n mask frames.
  • Development Reason: To avoid animation overlap, the first 16 mask frames need to be skipped.

Mask Generator

• Mask Generator: Generates masks of any quantity and size, in white and black.
  • Development Reason: To prevent errors caused by masks not corresponding one-to-one with images in the workflow, this component was developed to generate blank masks.

IntOperationsNode

• IntOperationsNode: Defines a node class that performs basic integer arithmetic operations, supporting addition and subtraction.

Features to be Developed

• Mask Editor: 1. Black in the middle, white outside. 2. Black from top to bottom.
