Upscale any YouTube or Netflix video to 4K HDR with an RTX card and Firefox

After debuting in Chrome and Edge, RTX AI-rescaled video comes to Firefox.

NVIDIA announced today the premiere of RTX Video Super Resolution and RTX Video HDR in the Mozilla Firefox browserin the v126 update that is now available for Windows.

With these functions, exclusive to users who have NVIDIA RTX cards, Any video played in the browser is upscaled by AI to 4K and HDR. The result is very similar to native video.

The quality is so good that many people are using it to subscribe to the 1080p version of Netflix, and convert it to 4K with HDR, saving a fortune. Works with all types of videos and streaming, including YouTube, Netflix, Disney+, HBO Max, etc.

This is how RTX Video works in Firefox

RTX Super Resolution It is similar to the DLSS upscaling that NVIDIA uses in games, using artificial intelligence, but applied to video. It is capable of upscaling videos with resolution between 360p and 1440p to 4K, up to 144 fps.

To use it, you must have the latest NVIDIA drivers installed. At the moment it only works with cards from the RTX 3000 and 4000 ranges, that is, from an RTX 3060 onwards.

Additionally, videos should play on Chrome, Edge, and now Firefox browsers. The only supported video player, outside of the browser, is VideoLAN. Here you can see how it works:

Keep in mind that if you want to play videos that you have on your hard drive, you can do so without problems by simply dragging them into the browser window.

To activate RTX Video you have to go to the NVIDIA Control Panel. We came in Video Settingsand we check the new super resolution box, where it says “RTX video enhancement”. There are four different qualitiesdepending on how much GPU resources you want to use.

Finally, we access the settings of the Chrome, Edge or Firefox browser, and make sure that hardware acceleration is enabled.

The truth is that it works quite well. The videos look better, sharper than if they were rescaled by the browser itself or the television / monitor without artificial intelligence.

It is much more noticeable if you have one HDR displayalthough in this case you will have to have the function activated Auto HDR of Windows 11.

It would be nice if This RTX Video technology, which upscales videos to 4K with HDR, using AI, is integrated into the operating system, or into the card drivers themselvesso that it worked by default on all videos, not just those played in browsers.
