I am well aware there is an issue, I suspected so upon my initial
commit.
However this updated value represents some kind of "goal" due to the
much better stddev compared to the previous value and thus makes more
sense.
Apart from this one reason I added the test is that dnxhd is similar to
DV in one more aspect: the encoder does not properly initialize memory
it needs to.
While unfortunately failing regression test seem not particularly
motivate to fix things, at least it will be documented that DV and DNxHD
encoders are not reliable.
