Video Super Resolution

Video Super Resolution is a Chrome Web Store extension (originally published and maintained by an individual developer, tsutsui.masayoshi0528) that targets a very specific annoyance: watching a video that is stuck at a low resolution. Instead of downloading and re-encoding the file, the extension intercepts the video element on the page and runs a deep-learning super-resolution model over each frame, displaying the result in the player at what the developer describes as roughly 720p-equivalent quality.

Because the model runs locally in the browser on your own GPU/CPU, the achievable frame rate depends heavily on your machine's performance — the extension's own listing notes this explicitly. A small popup accessible from the icon next to Chrome's address bar lets you switch the upscaling on or off at any time, so you can disable it on pages where processing power matters more than sharpness. The extension is entirely free, requires no account, and states that it does not collect or use your data.

The listng targets 360p and lower sources, so it is most useful for older or heavily compressed archives, free streaming content, and user uploads that were only ever published in low definition. It is a lightweight, install-and-forget utility rather than a full video editor: there is no rendering queue, no export step, and no cloud processing. Note that the extension only changes what you see in the browser — it does not create a new file you can save.
