# ByteDance vCube Video Enhance in ComfyUI

> Upscale and restore video with ByteDance vCube in ComfyUI: super-resolution up to 8K, artifact and noise removal, color and sharpness enhancement, and frame interpolation

ByteDance vCube is ByteDance's AI video enhancement technology. It upscales low-resolution video with super-resolution up to 8K while removing compression artifacts and noise, enhancing color and sharpness, and optionally interpolating frames for a higher frame rate.

In ComfyUI, the ByteDance vCube Video Enhance node takes a video, upscales it to a target resolution preset, and restores its quality. The source video must be at most 2560x1440, and the output size is set by the resolution input.

<Tip>
  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](/tutorials/partner-nodes/overview) section of the documentation to understand the specific requirements for using the Partner Nodes.

      Workflows in this guide can be found in the [Workflow Templates](/interface/features/template).
      If you can't find them in the template, your ComfyUI may be outdated.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

      * [Cloud](https://cloud.comfy.org) will update after ComfyUI stable release.

      So, if you find any core node missing in this document, it might be because the new core nodes have not yet been released in the latest stable version. Please wait for the next stable release.

### Node options

* **Scene preset**: Tuned to the content, with `aigc` for AI-generated footage, `common` for general video, `ugc` for compressed phone clips, `short_series` for drama with faces, and `old_film` for scratched or flickering archive footage
* **Enhancement style**: `hd` for a natural high-definition look, or `natural` for a softer result
* **Resolution**: Output presets from 720P to 8K, `source` to keep the source size, or a custom short side from 128 to 4320 pixels
* **Frame rate**: `source`, or 24, 25, 30, 48, 50, 60, and 120 fps. Rates above the source enable AI frame interpolation; rates above 30 fps cost 2x, above 60 fps 4x
* **Smoothness**: `low`, `medium`, or `high` bitrate level for the delivered file
