    I’m sharing a simple and efficient SeedVR2 video upscaling workflow for ComfyUI.

    This workflow is designed for fast, high-quality video upscaling, especially for client work where speed matters. It works well for both HD footage and low-resolution AI-generated videos, and upscales them cleanly to 4K. You can change the output resolution if needed, but this setup is optimized for quick turnaround.

    What This Workflow Does

    • Uses SeedVR2 for high-quality video upscaling

    • Maintains good temporal consistency

    • Ideal for AI videos and real footage

    • Simple node setup, easy to run

    • Optimized for fast client delivery

    Status

    This is a practical, working workflow, focused on speed and results rather than over-engineering. It’s what I personally use to upscale videos for client projects.

    Included

    • ComfyUI workflow file

    • Recommended settings

    • Notes on usage and resolution changes
