You can of course vary any of these settings to suit your specific needs.Ĭheck the capability of your installed version of x265 for 10bit encoding as follows: x265 -V -D10 ![]() c:v libx265 -preset medium -crf 28 -pix_fmt yuv420p \ An installation of FFmpeg compiled against this version of x265 can produce a decent 8bit encode with the following command: ffmpeg -i input.mp4 \ ![]() ![]() X265 : using cpu capabilities: MMX2 SSE2Fast SSSE3 SSE4.2 AVX XOP FMA4 FMA3 LZCNT you will see that my own copy has capabilities for 8|10|12 bit encoding. I illustrate a sample command line for each below:Ĭheck the capability of your installed version of x265 for 8bit encoding as follows: x265 -V If you have an appropriately configured modern version of FFmpeg and x265, (the repository FFmpeg under Zesty Zapus 17.04 falls into this category), you should find encoding with 8, 10 and 12bit fairly straightforward.
