{% capture content %}The x264 encoder supports both 4:4:4 as well as 4:2:0, as long as the underlying hardware is fast enough to handle it. It also has two different ways to reach each quality level: Constant Quantization Parameter (CQP) and Constant Rate Factor (CRF). Unfortunately OBS Studio only offers the latter, so for now we are stuck with that. With a single-PC setup, 4:4:4 recording using CRF will be very expensive. You might have to lower the preset used in order to maintain reasonable performance in game and encodes.{% endcapture %}{% include blocks/paragraph.liquid content=content %}
