ComfyUI-SeedVR2_VideoUpscaler
In one line
Gives ComfyUI extra nodes and example workflows for the LTX-2 video model
SeedVR2 video and image upscaling, as ComfyUI nodes or a CLI
Best for
Teams running LTX-2 locally on a CUDA card with 32GB+ VRAM, for video, control, HDR or dubbing work.
Editors finishing AI video who want a final upscale and restore step, in ComfyUI or on a multi-GPU CLI.

Features
  • Adds nodes under the LTXVideo category in the ComfyUI node menu
  • Ships example graphs for LTX-2.3, 2.5 and 2.0 text-to-video and image-to-video
  • Combines depth and edge control in one IC-LoRA (a small add-on model)
  • Converts SDR video to ACEScct HDR, with optional 16/32-bit EXR export
  • Dubs or rephrases speech and regenerates lips with the Dub-It IC-LoRA
  • Upscales video 2x or 4x with Pixel Spatial Upscaler IC-LoRAs
  • Upscales video and images with the official SeedVR2 restoration model
  • Ships 3B and 7B model configs and example ComfyUI workflows
  • Runs as ComfyUI nodes or as a multi-GPU standalone CLI
  • Processes long videos in chunks with --chunk_size, so RAM stays bounded
  • Writes 10-bit x265 video through FFmpeg with --10bit, cutting gradient banding
  • Works on CUDA, AMD ROCm and Apple Silicon MPS, with attention backend fallbacks
