CPU encoders (e.g., x265) are capable of the best quality, but are very slow. Hardware encoders are very fast, and are capable of decent quality. Your choice which you use. *** If you set anything in the render/encode toolchain to 8-bit, you'll only get 8-bit quality data out, even if everything else in the chain is 10-bit. That's just a simple mathematical fact.
