See this video: https://mega.nz/#!TDQHGSbK!BaI8lOZ4CQSDw7HG4Zc3QrHSWPhL4jeJWvyRCRPGiLg

If you examine it enough, you can see those weird artifacting on the skins of each character, anyone know what this is caused by? Apparently the other monitor, which I move the window around doesn't exhibit the same issue....

It's kinda started to bug my viewing experience.....

And no it's not an encoding error as this was taken straight from my phone as otherwise I wouldn't be able to reproduce it. Seems to happen on our TV as well and some of the blurays we watch....any ideas?

:confused:

I think we need more info about what you mean? The cell phone video is causing enough artifacts I am having trouble deciding what artifact you are seeing. :o

Is it the color blotching? It might be some of the TV's processing going bad, have you tried turning off things like any denoising, sharpening, or similar?

No, if you look closely in the faces of the people, you can see those weird artifacts happening, and I move the player over to another screen and the artifacts disappear.....

What is color blotching? Got an example or two showing what it should look like? Because I don't know what it is, that's why I came here! hahahaha:p

it's really really easy to see but that doesn't change that the source should be your end device and that there is nothing i can say about it.

@Asmodian it looks like 16x16 or even 32x32 macro blocks switching colors from frame to frame.

I'll give ya'll some screenshot comparisons, since the video I uploaded doesn't seem to do justice.....

You mean that Moiré ?
This would be dependent on playback screen resolution.
Interference with your digital camera's CMOS pattern leading to aliasing when picked up.

Not not the *moire*, sorry if I had a better camera to take a picture without those artifacts other interference that somehow got inside when capturing the photo, I would....:mad: I guess maybe pictures are better taken with a full on dedicated camera and not using your phone's camera......hahaha....

It's that blotchiness area around the character's skin all over in each scene, it's probably not very clear because of other crap that the camera decided to capture as well.... I would take a screenshot for a clearer shot except when I do, the fault isn't captured.....so that means the fault lies with the monitor hardware and not a software issue......

..................................................................................

Hm, it would appear changing monitor profiles seems to fix it......on the the Asus MG279, the GameVisual profiles Scenery, Cinema RTS/RPG and FPS modes exhitbit this fault, the only modes that don't have this are sRGB and Racing modes. It is more apparent on the scenery and RTS/RPG modes than it is on the other two....

Gee I really want to show you what I'm staring at but my shitty phone cam........:rolleyes::mad: Hmmm, I know, how about this one, I took a photo and saved the resulting image in a DNG format, so should be as original as it is before jpeg compression or other effects due to transcoding....

Here it is: https://i.imgur.com/VXHG4pa.png Oh....imgur converted it into a png file...... Here's a DNG file untouched hopefully: http://s000.tinyupload.com/index.php?file_id=86811557785586434396 *clears throat* Excuse the bright white circle, thought it might capture better if there was more light....which it did in this case!

@LoRd_MuldeR Yeah if your forum's spoiler tags existed I would have been able to done a dropdown menu like effect so you would still keep the format but if you want to see the picture, just click on the spoiler dropdown and it reveals the full image.....hahahaha

Wow, that really does make the issue much more obvious!

Unfortunately I don't really know what that could be, it looks like an artifact in the video is being horribly exaggerated by some "vivid" type video mode. A fake contrast enhancement stretching the difference in those shades.

If you cannot see those blotches in the source at all I have no idea what could cause them. :confused:
