Comment (by heleppkes):

 Contrary to its name, cpu-used doesn't actually control how much overall
 CPU is being used, it controls the quality of the encode, and both vp8 and
 vp9 could have different limits. The vp9 encoder doesn't scale well with
 high cpu core counts, so 50% already seems pretty good.
