====== ffmpeg - Encoding - h265 - Encode video as x265 HEVC 10bit ======

Do CRF 18 slow with x265 10 bit for high quality 1080p.

----

===== Encode video as x265 HEVC 10bit =====

<code bash>
ffmpeg -i "input.mkv" -pix_fmt yuv420p10le -c:v libx265 -preset slow -crf 28 -c:a copy -x265-params profile=main10 "output".mkv
</code>

<WRAP info>
**NOTE:**

  * CRF 20-23 for most 1080p videos is enough.
  * x265 uses CRF 18 by default.
  * Use CRF 23+ for videos in 4K.

===== Same as above, but as a two-pass x265 HEVC 10bit encode =====

<code bash>
ffmpeg -y -i "input".mkv -c:v libx265 -b:v 1500k -x265-params pass=1 -an -f null /dev/null && \
ffmpeg -i "input".mkv -c:v libx265 -b:v 1500k -x265-params pass=2 -c:a copy "output".mkv
