AMDs encoder lacks features that other vendors had for years, and simply do not hold a candle to Intels and NVIDIAs encoder. Still, you're not quite out of luck, as you still have NV12 recording as an option, which limits you to High or Acceptable Quality.{% endcapture %}{% include blocks/paragraph.liquid content=content %} +

If you decided to go with the "Red" team instead of "Blue" or "Green", then unforunately you're a bit more limited in throughput, quality and features. While AMDs "Fine Wine" does often improve things, their hardware usually only has partial support for a certain standard, and encoding is no different. However you can still do many things with the hardware, and is by no means outdated or bad - it's just an unfortunate situation.

Both have their own advantages and downsides, and it depends entirely on your requirements which one you should use. Modern {% include inline/link.liquid url="https://developer.nvidia.com/video-encode-and-decode-gpu-support-matrix-new" content="NVIDIA GPUs (Pascal and newer)" %} also all support 4:4:4 and 4:2:0 encoding at most of the quality levels shown here.{% endcapture %}{% include blocks/paragraph.liquid content=content %} +

The "Green" team has hardware capable of significantly more than the competition, and offers more flexibility in terms of configuration and quality. While not always the best in quality, and often optimizing for a different type of quality than would be expected, they are decent options with a variety of choices. NVIDIA has a good foundation in both live and offline content creation, and constantly aims to improve on this.

-{% include blocks/heading.liquid level=2 content="Constant Quantization Parameter (CQP)" %} -{% capture content %}Of the two methods available, CQP is by far the faster method, with hardly any noticable impact on other parts of the GPU. It also supports vastly higher framerates compared to the alternative method, thanks to NVIDIA optimizing their presets further. With the "Fastest (P1)" preset it is now possible to record 1920x1080 NV12 at nearly 460 FPS on an RTX 3080 or higher. Unfortunately none of my PCI-E SSDs, not even the PCI-E 4.0 from Samsung, managed to withstand the amount of data requested at once, so the exact upper limit is unknown.{% endcapture %}{% include blocks/paragraph.liquid content=content %} +
