Yes, it's something like RGX which is custom filtering with the Opera and Opera GX browsers: RGX filtering is a feature in the Opera GX browser designed to enhance the visual quality of YouTube videos and other online content. It applies a sharpening filter to improve clarity, contrast, and detail, making videos appear crisper and more vibrant, similar to an HD effect. Unlike traditional GPU-intensive sharpening technologies, RGX is built into the browser, requiring minimal system resources and no high-end hardware or premium subscriptions. If you have Opera installed you can use the "A|B" (Before/After) mode by hovering over the RGX button to compare enhanced and original quality. The effectiveness of RGX depends on the video's original quality. It significantly improves lower-resolution content (e.g., 480p), making details clearer, but may have minimal impact on high-definition videos. Some users report that RGX can over-sharpen, causing a "deep-fried" or overly contrasty look, and may reduce frame rates on lower-end systems. To mitigate this, ensure hardware acceleration is enabled in Opera GX, or adjust the RGX intensity (e.g., reduce from 100% to 75%) at opera://settings/lucidMode. The feature can be disabled in settings under "Show button on videos" if unwanted. YouTube is doing something similar and you can call it AI if you like but it's not. It evaluates areas of the video based on convolving patterns and applies some combination of noise reduction, sharpening, color-contrasting, saturation and/or smoothing to those areas depending on the returned results of the pattern detections. It's simple math and almost surely without "learning" tokens or neural decision networks etc. - Unless they like spending more than what's needed for some reason. Although I could be wrong and they've purchased some pretrained tokens - or it ends up that it was actually calculated to be cheaper than running the area detection lattices on every (key)frame - I wouldn't think so tho. In any case it's not AI in the common parlance where it's identifying faces, hair, guitars and shovels as themselves and substituting or blending "rendered" content with the videographed originals. You should be able to ask any AI or search the web on "How does the Opera RGX algorithm work? Generally speaking what steps and processes are the video frames going through? to find our more. Just when it gives it's explanation. substitute the word "Opera Browser" for "YouTube's Server".
