ComfyUI-AjoNodes

A collection of custom nodes designed for ComfyUI from the AJO-reading organization. It ships with utilities for audio processing and video frame interpolation.

Features

• Audio Collect & Concat
  • Collects multiple audio inputs.
  • Concatenates audio segments into one continuous output.
  • Checks for sample rate mismatches and raises an error if found.
• VFI Frame Skip Calculator
  • Generates a skip list for frame interpolation tools like RIFE.
  • Outputs the required interpolation multiplier alongside the list.

Requirements

• Python 3.x
• PyTorch – for tensor operations.
• ComfyUI dependencies:
  • comfy_extras (for audio utilities)
  • comfy_execution (for execution management)
• Ensure you have ComfyUI installed and properly configured before adding custom nodes.

Installation

1. Clone the repository:

   git clone https://github.com/AJO-reading/ComfyUI-AjoNodes.git
   

2. Place the custom node files in your ComfyUI installation:

   Typically, custom nodes reside in a specific directory within your ComfyUI installation—consult the ComfyUI documentation for details.

3. Restart ComfyUI to load the new nodes.

Usage

Once installed, you will see two categories of AJO nodes inside ComfyUI.

Audio Collect & Concat

• Location: Appears under the audio category.
• Input: Provide the audio tensor and the expected number of segments.
• Output: The concatenated audio and a count of collected segments.

VFI Frame Skip Calculator

• Location: Found under AJO-Nodes/VFI.
• Inputs:
  • source_fps – the frame rate of your input video.
  • target_fps – the desired frame rate after interpolation.
  • total_input_frames – number of frames in the original clip.
• Outputs:
  • skip_list_string – a comma-separated list of interpolation indices to skip.
  • rife_multiplier – the base multiplier for your VFI node (typically 2).
