Decimating a film source

[moko]

I have a 29.97 fps movie that is definately film, so it's supposed to be 23.976 fps. The movie was deinterlaced by repeating one of the fields, so there are some duplicated frames. Can I decimate the file to 23.976 fps, similar to decimating in avisynth (decimating repeated frames after telecide), in direct stream copy?

Just use Decimate(5) all by itself in Avisynth to serve into VDubMod.

I want to know if I can do that in direct stream copy in VDub, so I won't have to re-encode.

AviSynth spits out uncompressed video, so you can, but the resulting video will be uncompressed RGB/YUY2/YV12.
