<p class="block">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 However you can still do many things with the hardware, and is by no means outdated or bad - it's just an unfortunate situation.</p>

<h2 class="block">Additional Information</h2>
<ul class="block">
	<li>OBS Studio does not yet have a HDR capable format for 4:4:4. (State: 2023-04-23)</li>
	<li>More B-Frames may result in smaller files, but also more encoder usage.</li>
</ul>
