# WaveSpeed FlashVSR

> Upscale low-resolution video to higher quality using WaveSpeed's temporal-aware FLSH-VSR super-resolution model in ComfyUI.

WaveSpeed FlashVSR (FLSH-VSR) is a temporal-coherent AI video super-resolution model that upscales low-resolution video while maintaining consistent detail across frames. Ideal for archiving, AI video enhancement, and SD-to-HD conversion.

## Key capabilities

* **Temporal-coherent upscaling** — Maintains frame-to-frame consistency for smooth, realistic output.
* **SD-to-HD conversion** — Upscales standard-definition video to high definition with realistic detail.
* **AI video enhancement** — Ideal for archiving vintage footage and improving compressed video quality.
* **No local GPU required** — All processing runs on ComfyCloud's infrastructure.

> Workflows in this guide can be found in the [Workflow Templates](https://docs.comfy.org/interface/features/template.md).
> If you can't find them in the template, your ComfyUI may be outdated.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 users**
>
> * [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.
