Dedicated ComfyUI custom node pack for production-ready video import/export with FFmpeg profiles, mastering presets, sequence output, and image-batch-to-latent workflows.

Maintained by Geekatplay Studio.

Nodes

• UV_LoadVideo
• UV_SaveVideo
• UV_SaveMaster
• UV_SaveSequence
• UV_MetadataProbe
• UV_ImageBatchToLatent
• UV_CodecPreset
• UV_AudioMux

Install (Git Clone)

1. Clone into ComfyUI/custom_nodes/ComfyUI-UniversalVideoIO
2. Install deps: pip install -r requirements.txt
3. Restart ComfyUI

Install (ComfyUI-Manager / Registry)

• Ensure [tool.comfy] in pyproject.toml has your real PublisherId.
• Publish with Comfy Registry flow (comfy node publish).
• Then install/update from ComfyUI-Manager in one click.

V1 Coverage

• Pixel video import: UV_LoadVideo (frames + metadata + audio presence token)
• Video export: UV_SaveVideo (preset or advanced quality args)
• Mastering export presets: UV_SaveMaster
• Sequence export: UV_SaveSequence (PNG/JPG/EXR)
• Latent bridge: UV_ImageBatchToLatent (regular or tiled VAE encode)
• Metadata probe: UV_MetadataProbe
• Profile selector: UV_CodecPreset
• Audio mux: UV_AudioMux
• Transcode utility: UV_TranscodeVideo

Notes

• FFmpeg is resolved from system PATH first, then imageio-ffmpeg.
• V1 supports pixel-video workflows and IMAGE->LATENT bridging.
• Direct model-native latent video bridges are deferred to model-family-specific V2 nodes.
• Relative import fallbacks are included for ComfyUI custom-node loading contexts.
