blu ray = FullHD 4:2:0
blu ray 4K (master 4K) = UltraHD 4:2:0
blu ray 4K (master 2K) = FullHD 4:4:4

[DollyRanch]

You're kidding! I googled what the heck a "4:4:2" was just yesterday! Very timely vid guys, much appreciated :)

what does the 4x2 grid represent again? I box is a pixel right but the 4x2 grid is what?

Hi! Great video! But what is best combination for Windows HDR? RGB 444 with 8 bit or YUV422 with 10 bit? I am trying to configure HDR in Win/Nvidia control panel...

[jamesshort]

it isnt colour, it is hue. all the pixels have there own saturation and luminance.

"What do the numbers mean Mason."

[juaecheverria]

Since it's taking all 8 pixels and making 4 out of 8 of them one node of information wouldn't it technically divide the pixel count by 4? It would've been very nice to see what the effects are side by side from compressing images or video.

[JeffBourke]

Doesn’t make sense, so for a 420 picture, every second row of pixels duplicates the row above?

[topfamous]

my biggest problem: vlc can't play 4:4:4 yuv 10bit le. h265.

[ARC_VR]

Amazing tutorial dude! Absolutely what I wanted to know! I so love fucking with this sort of stuff haha.. Exemplary!

My hdmi cables are all marked as high speed hdmi (which only supports 1440p 144 at 4:2:0, but I have verified there is no subsampling on my 1440p 144 monitor. I have checked it is actually running at 144hz, not 60. What is happening? I cant see any reason the cables are not subsampling (I dont mind XD) except that they may be under represented in their branding and markings, and are actually premium high speed.

[aquaevitae]

I'v understood that all streaming services and also UHD Blu-Ray uses 4:2:0 subsampling at the moment. So at the moment 4:2:2 and nor neither 4:4:4 material is not available for consumer at all.

[armankizir]

Workflow and steps to make a 4k 4:2:0 to 4:4:4 1080p - any tutorials and guides?
