Clarity AI Crystal Video Upscaler raises the resolution of an existing clip instead of generating a new scene. It re-renders every frame at a larger size while staying close to the source, so faces, edges, and fine texture come back sharper rather than being replaced by invented detail. It is built for restoring compressed or soft AI video, upscaling generated clips for large screens, and giving edited footage a cleaner finish. In ComfyUI the model runs through the Clarity AI Crystal Video Upscale partner node. It is a cloud API node: it needs a Comfy account with credits and downloads no local model. You connect one video and get one upscaled video out, with the source frame rate and audio track carried over. See Partner Node pricing for the per-second rate. The node has a single control, scale_factor, which multiplies the width and height of every frame. The output is capped at 9 megapixels per frame and 360 megapixel-seconds per clip, so a long clip or a frame that is already large comes back upscaled by less than the factor you asked for instead of failing.

​
What Crystal Video Upscaler is good at

  • Faithful detail: re-renders frames larger while staying close to the source, instead of generating new content
  • Keeps the clip intact: the source frame rate and audio track carry over
  • One control: scale_factor sets how much larger the output is
  • Graceful limits: oversized or long clips are upscaled by a smaller factor rather than rejected

Use it

This runs on the same Comfy account and is billed in the same credits as running it in ComfyUI below. See Partner Nodes pricing for per-model rates and Concurrency limits for how many requests you can have in flight.
To use the Partner Nodes, you need to ensure that you are logged in properly and using a permitted network environment. Please refer to the Partner Nodes Overview section of the documentation to understand the specific requirements for using the Partner Nodes.
Make sure your ComfyUI is updated.Workflows in this guide can be found in the Workflow Templates. If you can’t find them in the template, your ComfyUI may be outdated.If nodes are missing when loading a workflow, possible reasons:
  1. You are not using the latest ComfyUI version (Nightly version)
  2. Some nodes failed to import at startup

​
Crystal Video Upscaler workflow

Load a clip, set the upscale factor, and run. The workflow sends the video to the Clarity AI Crystal Video Upscale node and saves the upscaled result.

Load into the LoadVideo node that feeds the Clarity AI Crystal Video Upscale node

​
Steps to run

  1. Load a video: upload or select your source clip in the Load Video node
  2. Set the scale factor: enter a value on the Clarity AI Crystal Video Upscale node. 2.0 doubles the width and height
  3. Click Queue or press Ctrl+Enter to generate

Limits

  • The output is capped at 9 megapixels per frame and 360 megapixel-seconds per clip. Long clips and frames that are already large are upscaled by less than the requested factor.
  • Each side of the source video is limited to 5120 pixels, and the scale factor is lowered to fit that limit.
  • Clips above 30 fps cost 2x, above 60 fps 3x, and so on.
