🎬 RTX Video Upscaler — Single & Batch Workflows
Two ComfyUI workflows that use NVIDIA's RTX Video Super Resolution to upscale your videos. One does a single video, the other processes a whole folder of videos automatically — no manual re-loading needed.
⚠️ Requires an NVIDIA RTX GPU. This won't work on AMD, Intel, or non-RTX NVIDIA cards.
What's included:
🎥 Single Video Upscaler — load one video, upscale it, save it. Simple and quick.
📁 Batch Video Upscaler — point it at a folder, queue it once per video (or set Auto Queue), and it works through the whole folder on its own.
Required custom nodes (install via ComfyUI Manager, search by name, or use the links below):
Nvidia RTX Nodes — the actual upscaler
ComfyUI-VideoHelperSuite — video loading/saving
ComfyUI-BatchVideoLoader — only needed for the batch workflow — lets you point at a folder instead of picking one file at a time
Quick start:
Install the nodes above through ComfyUI Manager
Load whichever workflow you need
For the batch one: set the folder path, then queue the prompt once for each video (or turn on Auto Queue)
Heads up: if you hit an error saving a video partway through a batch, it's usually one of two things — an odd-numbered resolution after scaling, or your GPU's video encoder being busy with something else. Both are covered in the GitHub README if you run into it.
