How to natively encode/decode H.264 videos on Ampere cards?

[cst1992]

I have a RTX 3060 Ti.
I've read in reviews that the Ampere architecture supports natively encoding/decoding H.264 and H.265 videos up to 8K 10-bit. Usually this is a very CPU-intensive process.
How to take advantage of this feature? Currently I'm using a software named AVIdemux for encoding videos.

With the launch of Premiere Pro 14.2, Adobe has added support for GPU-based H.264/H.265 (HEVC) hardware encoding which allows you to utilize specialized hardware built into NVIDIA and AMD GPUs to improve export performance when exporting to H.264 and H.265.

In previous versions of Premiere Pro, hardware encoding was supported, but only via Intel Quicksync. This implementation worked pretty well, but Quicksync is only available in Intel's consumer and mobile processor families. This meant that high-end Intel systems with X-series processors - and all AMD systems - did not have an option for hardware encoding. Quicksync is still supported if you do not have a compatible GPU, but support for AMD and NVIDIA GPU-based hardware encoding will not only allow almost everyone to have a method to greatly improve performance when exporting to H.264 and H.265, but should also be significantly faster than Quicksync.

you mean like that one?

Yes, kinda, but more generalized.
I guess this is still limited to proprietary software like Premiere Pro.

Doesn't Handbrake support Nvenc?

Yup. Handbrake (a really good ffmpeg wrapper - so really ffmpeg, but you have to learn all of the CLI/terminal arguments for for it) for encode, and most media players will use the decode HW of whichever GPU is supposed to render the display (though some will do otherwise).

There is nothing to do in order to enable it per say, you just select the encoder in whatever software you use.

I suggest tools like Handbrake because using the CLI tool for ffmpeg can be a bit daunting for the uninitiated.

I think encoders should come with a basic understanding and implementation of VMAF. I don't have to dial settings: I can push the available bitrate and for how long the recording is going to be, a video sample can be analyzed for the highest VMAF or another likely suitable scale.

For decoding there really isn't anything you have to do. If your software supports it, it will just use it.

For encoding I use xmedia recode when I want to use the nvenc encoder. I prefer it to Handbrake because it allows 2-pass encoding with nvenc while, as far as I can find, Handbrake only does single pass encoding. Also the encoder settings are much easier to tweak in xmedia recode.

Well, there is mainline decoding and then there is superxbr 75/100 & bilateral decoding. I would personally hope for the day MadVR has become the industry default. Let us leave the video to the japanese, guys. They know what they are up to.
Again, it shouldn't be hard to sample the psnr noise level of the video content and switch between 25/150(like a gaussian shock filter taking care of video fuzz in videotape media) and 75/100(standard media with extra font clarity).

Staxrip if you wanna really get into it?

Thanks guys for all the inputs
I'm not familiar with all the software mentioned here, but I'll check it out.
