Applying VDub Filters to Parts of an AVI File

[wwaag]

How do you apply a filter in VDub to only parts of the captured file? Here's my problem. For captured B&W movies, I use the grayscale filter to remove any traces of color--works well. However, I've just captured a movie that has a short part that is in color during the middle of the film. Is there a way that I can apply the filter only to selected parts of the file? Thanks.

I don't know if this helps, but why don' t you capture your movies using editing warez (like premier, pinnacle, or something) then contrast your whole movies into black and white. So, you won't have to worry about the color part in VirtualDub.

I think, the only way to do that with VirtualDub is to cut the movie, convert the selected part and join afterwards.
If you want to apply a greyscale filter to a part of the movie, you may try Avisynth.
#example:

clip = AviSource("c:\cap.avi")
Return Trim(clip,0,100)+Trim(clip,101,130).Greyscale+Trim (clip,131,0)
