Subject: Set default crf to 24

From https://trac.ffmpeg.org/wiki/Encode/H.265:

     The default is 28, and it should visually correspond to libx264
     video at CRF 23, but result in about half the file size.

This will result in larger videos. Maybe the default should be
libx265. I did try it, results in smaller videos but I wasn't able to
play the video on Firefox.
