Previous Next. Apr 17, 4 0 0. I'm not sure if it's a faulty monitor or the settings I'm using, but the color red and sometimes any color close to red on my monitor a Sceptre , appears very pixelated and almost too bright.
When it's outlined with a darker color, it's much worse. It almost looks like the image was saved with bad JPEG quality. When I zoom in on the image, either with a graphics editing program, or by using the zoom in function on my browser, the problem goes away.
It is also only the color red. I make graphics on the side, so not being able to work with the color red has been a problem, because it always looks, well, ugly, pixelated and way too bright. I've had this problem for a while now, but I've never been able to find a similar question. Maybe I'm just not looking hard enough. I've included some pictures of what I mean. Hopefully they are clear enough as they were taken with an iPhone. I don't have any other camera.

I think the issue you see here is actually because of bright pixels against a very dark background. Most lossy compression takes into account that we are far more perceptive to lightness differences than we are color differences.
Depending on the codec used, and encoding options chosen, the blocks used for approximating the video can be fixed size, which appears to be the problem in your video.
As you get to the edges of the light, you find edges which cannot be quantified with the large block alone. Many codecs support subsampling where the larger blocks are subdivided into smaller ones. There may not have been enough available bandwidth especially common with fixed-bitrate streams to use subsampling, the option may not have been enabled, or it might have not been available on the codec used. In short, you've found a part of the frame that is difficult to encode with many lossy codecs, and becomes easily visible depending on the configuration of the encoder.

For a two row rectangle of pixels the numbers represent: "width of sample region Y samples ":"UV samples in the first row":"additional UV samples in the second row" A common example of this notation is in the codec name "proRes" the part of the name comes from meaning for every a 4x2 rectangle there will be 4 Y samples in each row 2 UV samples in the first row half the horizontal resolution and 2 UV samples in the second row.
This means the red channel on its own has one quarter the resolution of the overall picture. TL;DR the red looks pixelated - because it actually is. Improve this answer. To add to this, I would consider the pixelation a bug, chroma can be, and should be upscaled using a bilinear or better algorithm, but Windows doesn't seem to do the upscaling correctly, 3rd party apps like Kodi, that implement upscaling in pixel shaders do not show this artifact.
You can see here with bilinear turned on: i. Since VCD cannot be made in , or , there is no solution to this problem. Replies: 2 Last Post: 6th Sep , I need a genuis!!! Heavily red tinted or red hue.
