In principle you are correct that it "should not be needed". However
there are numerous cases where the heuristic that chooses the output
format may do dumb things. This is particularly the case when dealing
with interlaced modes (where it might for example pick 1080/30psf
instead of 1080i/59).
I've got a list of bugs in that area that need attention, but even
with those fixes I want to be able to force the format in an
It's on my TODO list.
