# Pruna P-Video Upscale: Upscale Video to 720p, 1080p, 2K or 4K

> Upscale video to 720p, 1080p, 2K or 4K in ComfyUI with Pruna P-Video Upscale: it keeps the aspect ratio and audio, and can interpolate up to 60 fps.

Pruna P-Video Upscale enlarges a finished clip to 720p, 1080p, 2K or 4K. The output keeps the aspect ratio and the audio track of the source video. The frame rate stays at the source rate, is interpolated up to 60 fps, or is lowered by dropping frames.

The node is **Pruna P-Video Upscale**, in the `partner/video/Pruna` category. It takes any video output, from a **Load Video** node or from a generation in the same workflow, and returns the upscaled clip, so you can chain it after a text-to-video or image-to-video node.

It runs on Pruna's servers through the Comfy API. No model downloads or local GPU are required; you need a Comfy API account with credits.

## Add it to a workflow

1. **Add the node**: right-click the canvas and search for **Pruna P-Video Upscale**, under `partner/video/Pruna`
2. **Connect a video**: wire a video output into the `video` input
3. **Pick the target**: `720p`, `1080p` (default), `2K` or `4K`
4. **Set the frame rate**: `source` keeps the input rate up to 60 fps; a higher rate is interpolated, and a lower rate drops frames
5. **Save the result**: connect the output to a **Save Video** node
6. **Click Queue**: press `Ctrl+Enter` to run it

## Node controls

| Control | Values | Effect |
| - | - | - |
| `video` | video | The clip to upscale. The 512 MiB limit applies to the MP4 the node prepares, not to the file you load |
| `target` | `720p`, `1080p`, `2K`, `4K` | Output pixel area of about 0.9, 2.1, 3.7 or 8.3 megapixels. Default `1080p` |
| `fps` | `source`, `16`, `24`, `25`, `30`, `48`, `50`, `60` | Output frame rate. `source` keeps the rate of the input, capped at 60; a lower rate drops frames |
| `turbo` | on / off | Faster upscale with softer detail, at the same price |

## Limits

* A source larger than the target comes back at its original size, so a 1080p clip sent to `720p` stays 1920×1080
* Length is capped per target at 2400, 1200, 600 or 300 frames for `720p`, `1080p`, `2K` or `4K`, counted at up to 30 fps. That is about 100, 50, 25 or 12.5 seconds at 24 fps
* Clips above 10 megapixels must target `2K` or `4K`
* The input is re-encoded to H.264 MP4 before it is uploaded, and the 512 MiB limit applies to that prepared file, not to the original. The audio track is carried through to the result
* Outputs above 30 fps cost twice the per-second rate, including when `source` keeps a source rate above 30

## Pricing

Pruna P-Video Upscale bills per second of output video, and the rate depends on the target. See [Partner node pricing](https://docs.comfy.org/tutorials/partner-nodes/pricing.md) for current rates.
