Enable Additional Hardware Accelerated Decoding Support for H.264 and HEVC Footage

An update:

The official release version 25.3 is now available. Currently, only Blackwell-architecture Nvidia GPUs support hardware 10-bit 4:2:0 and 10-bit 4:2:2 H.264 decoding, while hardware 10-bit 4:2:2 HEVC decoding is a first for Nvidia (Intel and Apple GPUs already support hardware 10-bit 4:2:2 decoding for HEVC).

Thanks for the clarification.

@RjL190365 I was looking for a post on our forum and came across this thread. As mentioned in the link @mayjain7130546 provided, we are working on supporting H.264 and HEVC 10-bit 4:2:2 in the NVIDIA Blackwell Architecture-powered GPUs. 

I did want to comment on something you said back in January:

"I am also expecting Nvidia to unlock 4:2:2 hardware decoding and encoding support (at least for HEVC) in its Turing and newer-gen GPUs beginning with driver branch 570"

If you're referring to 10-bit 4:2:2, that will only be available in Blackwell. It's a change in silicon that cannot be made available in older NVIDIA GPUs.

Hi @RjL190365,  @Eccentric Locust and everyone,

Similar discussion happened on this post:-

As mentioned by Fergus, "We've been working closely with Nvidia to support their new GPU.... "

Thanks,

I am also expecting Nvidia to unlock 4:2:2 hardware decoding and encoding support (at least for HEVC) in its Turing and newer-gen GPUs beginning with driver branch 570, which is due to be released whenever the Blackwell GPUs start shipping to distributors.

Adobe users may have to wait longer for this support to be added to its Nvidia codec.

@Daniel Laan Actually, it still stands! I did see the announcement at CES 2025 for 4:2:2 encode and decode for the latest RTX 50-series GPUs, which is great to see!

However, it is up to Adobe to impliment support for it in their software; which after the announcement, I hope it happens soon.

For instance, the RTX 4090 supports 4:4:4 encode/decode on codecs like H.264 and HEVC. But Adobe doesn't have support for that at the moment.

This didn't age well. NVidia supports 4:2:2 encoding and decoding on Blackwell as announced at CES 2025.

Hi.
You don't have to go far here. Everyone who works or is related to color knows and understands perfectly well that it is impossible to paint good frames in 8-bit color. There is a severe destruction of pixels when creating a certain concept of a cinematic look. Just look at how many colors are contained in an 8-bit color. That's right, 16.78 million in color. And how much is in 10-bit? Billions already. To be more precise, 1.07 billion. I think it's not even worth persisting and squeezing out 8-bit sources to achieve the desired result. Modern cameras shoot in both 12 and 16 bit color, and just imagine what a difference it will be with the previous ones (12-bit = 68.68 billion!). If anyone here says that I paint and 8-bit is enough for me, for God's sake. But not for everyone, including me. The density of color in the modern world is important for flawless work and creating an amazing product that is pleasant to look at.
Good luck to everyone.

Recently, I have made research on this topic and went already through the same links and resources here posted/ mentioned.

Firstly, I strongly support the point made by @Eccentric Locust , and @Baffy19 . I am using Sony A 7IV, in which we have

XAVC HS  (H.265) - Highly compressed

XAVC S  (H.264) - Medium compressed

XAVC S-I  (H.264) - Mostly un compressed

options for 4K videos. The chroma subsampling choices varies with different fps and bit depths (8 or 10).

I would love to edit with uncompressed XAVC S-I  (H.264), 60fps where I am only opt to 10-4:2:2 depth and chroma subsampling.

Due to 10 - 4:2:2 this is not possible in Adobe premier, unless you have intel iCPUs which is capable of it. I DO NOT WANT TO UPGRADE, only for this reason, I am asking why it is not possible for GPU manufacture can not support the latest and best bit depths and chroma subsampling??

I am greatly disappointed, that I have to make proxies for my work otherwise have to shoot, 4:2:0.

The thing I do not understand is, the highly compressed codecs (i.e. XAVC HS  (H.265) ) usually suppose to take CPU rather GPU according to the difficulties in the post describing. But adobe support the H.265, 10-4:2:0 even 60fps, for GPU acceleration.

@Adobe  @NVIDIA @AMD Please take this topic as one of the feature request for future software - driver updates!

Being, a Software developer, I do not see the difficulties writing the codecs for other various bit depths and chroma subsampling, if you already have one or more working/ supporting format, that already released!
