ComfyUI-SeedVR2_VideoUpscaler

Why we included this project

People restoring old footage or trying to make gameplay captures look decent on modern displays will appreciate having ByteDance's SeedVR2 one-step diffusion upscaler available as a ComfyUI node. You can drop it straight into an existing node graph, or skip ComfyUI entirely and run the bundled multi-GPU standalone CLI to batch upscale whole clips on a dedicated box. It handles both video and still images, and the maintainers have paid attention to the messy details: memory usage across CUDA, ROCm, and Apple Silicon, plus GGUF-quantized VAEs for cards with limited VRAM. The changelog shows fixes for ffmpeg hangs, 10-bit encoding, and backend fallbacks, which is exactly the kind of reliability you want when processing long sequences. If your team wants a reproducible upscaling step that.
