ComfyUI Universal Media Loader: one node for loading, cropping and masking
3deal · reddit · 2026-08-25
The author open-sourced ComfyUIUniversalMediaLoader, replacing the usual pile of loader nodes (Load Image, Load Video, VHS, audio loaders) with a single interactive node:
- Load anything: PNG/JPG/WEBP images, MP4/MOV/WEBM video, animated GIFs, WAV/MP3/FLAC audio — just drop it in
- Canvas Planner mode: acts as a resolution/aspect planner (1:1, 16:9, etc.) with 32px grid snapping and megapixel clamping for SDXL/Flux latents
- Visual crop & outpaint: interactive bounding box with aspect locking; pulling beyond bounds auto-generates outpaint masks and padding
- Inpaint brush: draw masks inside the node with brush/eraser and wheel-controlled size
- Video/GIF timeline: trim handles, scrubbing, custom FPS resampling, frame extraction
- Audio waveform & speed: waveform display, 1s magnet snapping, pitch-preserved 0.10x–4.00x time-stretch
Four modular unpack nodes output exact sizes, images (with a 3-frame batch), audio dicts, and video frame batches. Open source on GitHub.
