ive used tinterlace (from mplayer) myself in the past and it worked
fine. Quite likely these where very different use cases than what you
and kierank use these filters for though.
If theres a problem in tinterlace as you keep hinting at, could you
please explain what this problem is or provide a testcase that shows
the problem?
I would like to fix tinterlace and for that i need to know what does
not work with more detail than just a vague hint that something doesnt
work
