![]() I use constant quality encoding and adjust it repeatedly after seeing the results until I feel I've reached the best compromise, and I almost always use 10-bit for both H.264 and H.265. In x265 the big jump in quality is when you switch from medium to slow, so you can go further but it's a lot of time of encode. If you want x265 you can start with CRF20, slow preset is a good start to test, but for blu-ray movies I prefer x264, it's better in my opinion, much sharper and detailed (even with the sao option off). For a same CRF a 2 hours cartoon can have a final size of 3GB and a 1h30 movie 6GB. Test your self and see which preset/CRF it's good for you. ![]() For example a very good quality for blu-ray is CRF18 with veryslow preset, if I increase the CRF, the bitrate will decrease and the quality little worse, if I decrease the CRF, the bitrate will increase and better quality. I encode my blu-ray at H264 veryslow preset with CRF 18.Ī cartoon needs much less bitrate than a grainy movie, and a grainy movie much more bitrate than a standard movie, as you don't know what bitrate is needed, the CRF will adapt itself to the complexity of the content. Unless you need to stream or achieve a specific size the bitrate is obsolete. ![]() Don't use the bitrate, use the CRF, it's a indicator of quality when you use the same preset. ![]()
