🎬 ComfyUI Auto-Edit Workbench

A powerful Custom Node for ComfyUI that acts as a mini video editing studio. It automatically assembles (concatenates) multiple video clips from a folder into a single sequence, handling resolution resizing, aspect ratios, and frame rates intelligently.

✨ Key Features

• Batch Assembly: Loads all video files from a specific folder automatically.
• 3 Resize Modes:
  • Crop (Fill Screen): Fills the screen, cropping edges if necessary (perfect for mixing vertical/horizontal footage).
  • Fit (Black Bars): Adds black borders (letterboxing) so the entire video is visible.
  • Stretch: Distorts the video to fit the target resolution perfectly.
• Smart Strategies:
  • Resolution: Auto-detect from the First Video, Smallest, Largest, or use a Custom size.
  • FPS: Auto-detect from First Video, Lowest, Highest, or Custom.
• Audio Support: Concatenates audio tracks seamlessly.
• Safety Limits: limit_duration_sec parameter to trim the output (great for testing without Out-Of-Memory errors).

2. Clone this repository:

   git clone https://github.com/Verolelb/ComfyUI-Video-Workbench.git

3. Open a terminal in this folder and install the requirement:

   pip install -r requirements.txt

   (This node relies on moviepy and numpy).

🛠️ How to use

1. Inputs

• directory_path: Absolute path to your video folder (e.g., C:/Users/You/Desktop/MyClips).
• sort_strategy: Order of clips (Alphabetical, Date, Random).
• resize_mode:
  • Use Crop for immersive, full-screen montages (e.g., Shorts/Reels).
  • Use Fit to preserve all details with black bars.
• resolution_strategy: Keep it on "First Video" to let the first clip dictate the format of the whole timeline.
• fps_strategy: Keep on "First Video" or force a Custom value (e.g., 24, 30, 60).

2. Outputs

1. IMAGE: The assembled video stream.
2. AUDIO: The combined audio track.
3. FLOAT (fps): The final frame rate (useful to connect to the "frame_rate" input of saving nodes).

3. Recommended Workflow for Saving

To save the video with audio, it is highly recommended to use the Video Combine node from the ComfyUI-VideoHelperSuite.

• Connect AutoEditWorkbench IMAGE -> Video Combine images.
• Connect AutoEditWorkbench AUDIO -> Video Combine audio.
• Connect AutoEditWorkbench FPS -> Video Combine frame_rate (Convert widget to input).
• Set format to video/h264-mp4.
