Since someone other than myself set the flag on this command, I am
trying
to figure out what effect, if any, taking it off will do to the
output.
IIRC, it only has an effect when you are creating an interlaced output
using -top 1, (and from here on I‘m guessing) it might instruct the
encoder
or an automatically inserted filter to apply the DCT in a different
fashion
compared to a progressive input.
But again, that’s a guess which may (also) be outdated, since I last
did
these kinds of transcodes quite a while ago.
Good luck.
