1. Workflow Overview

Developed by SoilSighStudio, this workflow is designed for video effects composition, combining multiple video clips (e.g., ink effects, light leaks, fades) with static images to generate dynamic videos. Key features:

  • Multi-track video compositing

  • Dynamic mask processing (e.g., fade-in/out, flash transitions)

  • Audio integration (background music/SFX support)

3. Key Nodes

  • VHS_LoadVideo: Loads video clips with frame rate control.

  • FrameSelector: Selects specific frame ranges (e.g., 0-30).

  • ImageToMask + InvertMask: Converts frames to masks for effect blending.

  • ImageCompositeFromMaskBatch+: Merges masks with background videos/images.

  • VHS_VideoCombine: Final video export with audio (MP4).

4. Workflow Structure

Organized into 8 effect modules (Groups), each handling a specific effect:

  1. Ink Effect: Processes ink-wash video layers.

  2. Light Leaks: Overlays light flare clips.
    3-8. Fades/Flash Effects: Controls transparency via masks.

Inputs:

  • Video clips (e.g., 片头水墨0.mp4, 闪白0.mp4)

  • Static images (e.g., 2 (1).png)

  • Frame count settings (e.g., 30/64 frames)

Output: Composite MP4 video with audio.

5. Important Notes

  • Model Dependencies: Download FLUX models (UNet, VAE, CLIP) to specified paths.

  • VRAM: Recommended ≥8GB GPU.

  • Troubleshooting:

    • Use ASCII paths for video files.

    • Ensure frame counts match source videos.

  • Optimization: Enable xformers for faster processing.
