I've been having a lot of issues with getting VLC to properly detect and run deinterlacing on several videos I've tried to watch, especially anime. Very often it will fail to detect the visibly interlaced video. If I force deinterlacing the typical methods seem to work as expected but the important one for me, IVTC, won't work.
IVTC is really useful for anime and other animated content because it's lossless and won't cause any artifacting. No matter what I do, it seems like the IVTC filter will not do any deinterlacing, even when I have deinterlacing forced on. I'd love any help that's available because this has been bothering me for several VLC versions.
