For the unfortunate souls who bought an AMD GPU on the belief that AMD can fix their encoder via Drivers, unfortunately "Fine Wine™" only goes so far. 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.
True Lossless
At the time of writing this, AMD does not have an encoder capable of 4:4:4 encoding.
Effective Lossless
At the time of writing this, AMD does not have an encoder capable of 4:4:4 encoding.
Visually Lossless
At the time of writing this, AMD does not have an encoder capable of 4:4:4 encoding.
High Quality
As no AMD encoder supports 4:4:4, you're free to use NV12 here. Ensure your Color Format is set to NV12, Color Range to Full, and that your Color Space matches the content.
Acceptable Quality
As no AMD encoder supports 4:4:4, you're free to use NV12 here. Ensure your Color Format is set to NV12, Color Range to Full, and that your Color Space matches the content.
