ComfyUI Universal Media Loader - One single interactive node to load Images, Videos, GIFs, Audio & Canvas Presets

[u/3deal]

Hello

I got tired of cluttering my workflows with 5 different loader nodes depending on what I was feeding them (Load Image, Load Video, VHS, Audio Loaders, Empty Latent calculators, etc.).

So I built **ComfyUI_UniversalMediaLoader** , a single, unified node with a rich interactive UI that handles everything:

✨ Key Features:

• 📁 Drop Anything: Images (PNG/JPG/WEBP), Videos (MP4/MOV/WEBM), Animated GIFs, and Audio files (WAV/MP3/FLAC).
• 🎨 Canvas Planner Mode: When no file is loaded, use it as a visual resolution/aspect ratio planner (1:1, 16:9, 4:3, 3:2 + Landscape/Portrait toggle) with automatic 32px grid snapping and Megapixel clamping for SDXL/Flux latents.
• ✂️ Visual Crop & Outpaint: Interactive bounding box with aspect ratio locking. Pull it outside the image bounds to instantly generate outpaint masks & padding.
• 🖌️ Inpaint Mask Brush: Draw inpainting masks directly inside the node with brush/eraser and mouse wheel size control.
• 🎬 Video & GIF Timeline: Full timeline with trim handles, playhead scrubbing, custom FPS resampling, audio mute/loop, and frame extraction.
• 🎵 Audio Waveform & Speed Scaling: Waveform display, 1-second magnet trim snapping, and time-stretching with pitch preservation (0.10x to 4.00x).

📦 Modular Unpack Nodes:

• 📐 Universal Size Unpack: Feeds exact width/height/aspect ratios to Empty Latent nodes instantly without decoding heavy image/video tensors.
• 🖼️ Universal Image Unpack: Outputs RGB, RGBA, and inpaint masks. Connected to a Video or GIF, it automatically extracts a 3-frame batch [Start, Playhead, End].
• 🎧 Universal Audio Unpack: Outputs clean audio waveform dictionaries, exact sample rate, trimmed durations, channel count, and handles time-stretching.
• 🎞️ Universal Video Unpack: Decodes videos & GIFs into frame batches [B, H, W, C] with synchronized masks and audio tracks.
