Doesn't this serial ordering of the same command (-c:v xxxx) twice just
drive cpu workload up for no actual benefit? 

To clarify:  executing -c:v xxxx and then executing -c:v yyyy just
causes one output: yyyy.   Thus you are forcing the CPU to
decode:encode:decode:encode rather than just decode:encode.... can
someone confirm or correct me here?
