is it possible to add null frame ?

I have a VFR h264 mp4 and want to transcode to xvid avi.
since avi does not support vfr so I'm thinking about

say the VFR mp4 has three different frame rate

then I want to normalize the 23.97 fps
so 23.97 keep unchange
29.97 turned to 23.97 by deleting duplicate frame
20.00 , adding null frame to make it 23.97

is it possible ?

You can't create null frames (it doesn't make sense; AviSynth outputs uncompressed frames), but you use DuplicateFrame to duplicate a frame. (Or if you need to do it a lot, you could use my RemapFrames plug-in.)
