Source/output frame maps

When you use Kerndeint or Fielddeint and set map=true is there any way to keep the map out of the VDUB source frame? (ie. the map shows up in both source and output frames and there's no way to look at the source interlace lines themselves). When you use an internal VDUB deinterlacer like Area-based or Smart the map will only show up in the output frame. So it's really handy to compare the two frames and the interlace lines to see if you are catching them or not with the deinterlacer.

VirtualDub receives the already filtered video from Avisynth. There is no way it can show the unfiltered video (unless you remove the filter from the Avisynth script). You can make two AVS scripts, one with the filter and deinterlace map enabled and one without the filter. Then open each in its own VirtualDub instance. You can compare things that way.

Or make script like this: A=WhateverSource() B=A.Whateverfilter() Interleave(A,B) That will show the clips in this order source frame 1, filtered frame 1, source frame 2, filtered frame 2 etc.

Thanks a lot. That will help me out greatly.
