4k 12bit 4 4 4
I would be happy with HDR at 422 10 or 12 bit if the picture actually looked okay. They say DV supports up to 12-bit color depth.
Canon Working On Cinema Eos C500 4k Professional Rig
I cant imagine that since nVidia RTX30 GPUs support 4k120hz 12bit 444 RGB full HDMI 21 48Gbps bandwidth just fine.
. This camera will record DCI 4K internally in 10-bit 422 ProRes or even better in CinemaDNG raw. The core architecture is optimized for very low resource utilization. I suppose it works because 4K 30 Hz with 12 bit RGB 444 fits within the available display interface bandwidth.
Not happening at 4k without lowering quality significantly - 1440p would look better. HDMI 20 is capable of 444 60Hz 4K at 8bit color. Its only with 4K 60fps that you have to choose between 8 bit 444 or 1012 bit 422 with the latter being the correct choice for most content as youve explained well.
Anyway 444 is better than 422 which is better than 420. Or 12-bit color depth with 422 chroma Thanks in advance. 444 doesnt work in HDR at all due 10 12 bit not being supported.
Now lets take a look for 422. 4K 420422444 81012 bit HEVC Decoder. Chroma subsampling is the first thing they hit to reduce bandwidth because its the least noticeable.
8 Channels of Audio. Starting a thread for verified 4K TVs that can do 444 at 60Hz over HDMI 20. 10bit is very good 12 bit is more than you need to make a perfectly smooth ramp from pure black to 10000 nits of brightness which is why Dolby made their dobly vision a 12 bit format.
The Odyssey can also accept 4KQHD RAW up to 30fps debayer it and turn it into high quality 4KUHD Apple ProRes video. 128 AES Bit Decryption. 8-bit color depth with 444 chroma.
This means if I play at 30 FPS in 4K I can use 12bit 444 but I doubt Ill see any difference between 8 and 12bit in 444. Iris 4K 12-bit 444 1 Month Activation provides. And you need glass -- its Micro Four Thirds mount offers the largest selection of native cinema and general.
What are the drawbacks of chroma subsampling other than slightly worse readability of text. But actually it doesnt matter what you have everything set. I thought all these should work well in getting me 4k120hz 12bit 444 RGB but it is limited to 4k120hz 10bit 444 RGB or 4k60hz 12bit 444 RGB which basically means 40Gbps.
Increasing color depth from 8 bpc to 10 or 12 has very minimal impact. However it looks like they encode into 10-bit HEVC for 4K blu-rays. Those are two games I see people mentioning support higher colour bit depth or whatever it is tbh Im still a bit lost.
4 12BIT according to the HDMI CAN BE ONLY 8BIT standard maximum color. You can set your Blu-ray player 444 and TV 420 and it wont make a difference. Ill try Alien Isolation and Witcher 3 to find out though.
It looks like the display controller only supports HBR2 ie. This part isnt clear. 10bit or higher it cant do 444 but for the most part thats not an issue.
And the third 2 means two chroma subsampling in the second row too. I didnt think it was said to not work. The display is an LG C9 OLED.
However 4K Blu-ray titles with Dolby Vision enhancement layer is what confuses me. The body today runs 1300 MSRP -- cheap. Image up to 4K 60FPS 4.
Its very unlikely youll ever notice the difference between 10bit and 12bit with a consumer monitor. Is it really the maximum bandwidth with the RX6900XT. LG CX limit 10 bit 444 4k120 LG C9 limit 12 bit 444 4k120 Edit.
HDR works but with very poor picture quality at 420 422 at 10 12 bit but not at 8 bit. So to summarise that. DisplayPort 12 mode but not HBR3 mode in spite of being advertised as DisplayPort 14 - and HBR2 is not enough for 12 bit 60 Hz in RGBYCbCr 444.
Technically speaking 444 represents each pixel has its own color value which includes all the chroma information so it isnt chroma subsampling. So we need HDMI 20 but not HDCP 22. The second 2 means two chroma subsampling in the first row.
Only minor clarification HDMI 20 can do 444 with HDR 1012 bit as long as its 4K 2430fps. RGB is superior to YCbCr 444 and much better than YCbCr 422. VRR has a known issue but with your 3090 if you run 1440p you should get 140-200 fps in everything with most settings maxed.
The RAW Bundle Upgrade is not required for this as the Odyssey7Q7Q can record these formats in uncompressed video DPX files. Unlike fulllimited range theres no clipping with chroma or anything. C300MKII can also output 2K or HD 12-bit RGB 444 video.
HEVC video decoder IP core by ParaQum Technologies is an all-hardware high performance video decoder which is easily integrable to complex FPGA based SoCs and supports upto 4K video decoding upto 60fos on Xilinx 7 series FPGAs. Switching to YCbCr with sumbsampling has a worse impact. My guess is that 12-bit 422 is better because it will enable the DCI-P3 color gamut for HDR games.
The main issue with most HDMI 20 TVs at the moment is HDCP 22 uses up too much bandwidth to do 444. From my searching it seems that 12-bit color is used at mastering stage in the studio for DV.
