Comment (by AmshTemp):
Unfortunately the {{{ deinterlace=advanced }}} produces the same result as
{{{ deinterlace=bob }}}.
Perhaps my wording wasn't precise enough to point out the problem. So I
will try to do better with examples.
Yadiff (with Bob) takes every "field" in 50i and converts it to a frame in
50p, which produces the smoothness you would expect from such a
conversion.
For vpp_qsv, however, it seems that vpp_qsv converts the 50i source to 25p
and then just doubles the framerate to 50p, which results in a non-smooth
50p
NOTE: I attached two videos demonstrating the output difference between
Yadiff and vpp_qsv
