[HELP] Please help me deinterlace my stupid NTSC DVD cartoons

[Selur]

no sane person does that

No. Sane persons don't:
a. use interlaced content nowadays
b. don't create mixed content
c. masters DVDs as crappy as a lot of (the older) animes and cartoons are mastered

Best ways to handle mixed content are:
a. keep the content as it is
b. bob everything
c. produce progressive vfr content
interlaced content at 29.97 fps has 59.94 fields with different motion data, to make sure you keep all the motion the easiest way is to bob.
Staying at the same frame rate and keeping all the motion data isn't possible.
