What it does is quite simple: It detects frames that look (still)
interlaced and tries to drop them.
I expect is intended to be used with incorrectly inverse telecined content
to get rid of any bad-looking frames.
Due to this, it will never drop more than one frame in a row, since
that would look bad and is likely to mean that the interlace detection
didn't work right.
I don't know if the two filters you mentioned can achieve this
behaviour together, though I would guess it should not be hard to
implement if they do not.
