Quick Deinterlacing Question...

[LeoH]

Well, I think it's quick anyway

Basically I've got a PAL DV file which was dubbed from a PAL BetaSP which came from a film source. The original film was shot at 24fps but I'm assuming they did the 4% speed-up when doing the telecine at 25fps. Anyway I'm trying to deinterlace this sucker the best way possible. Once I get to real 25p I'll convert it back down to 24p.

Here is a frame from the source:



My first try in VDub was with the filter "deinterlace - PAL movie v1.1 (normal)" and it seems to be doing the right thing. Here is the same frame after filtering:



My question is, why am I still getting (albeit minor) comb artifacts on the edges? My paranoia says that I must be doing something wrong - or is this "normal" when deinterlacing, to have some minor artifacts still? Am I approaching this in the right way or should I be doing something else?

Here's a short clip of the material:

Many thanks in advance for any help!
