quality) as the human eye usually does not have time to see all the bird's

Be warned that if the masked object stops (e.g.\& the bird lands) it is
likely to look horrible for a a short period of time (until the encoder
figures out that the object is not moving and needs refined blocks).

The saved bits will be spent on other parts of the video, which may increase
subjective quality, provided that tcplx_mask is carefully chosen.

Larger values help against blockiness, if no deblocking filter is used for
decoding, which is maybe not a good idea.
