I know AutoGK uses the excellent avisynth plug Autocrop, but wonder if there is a similar plugin for Virtualdub which I use now as it is regularly updated? It would be helpful for videoconverting using the xvid codec when cropping say widescreen 624 x 352 etc and save doing the manual crop to get rid of black bars and utilize fully the bitrate.

I have tried the plugin packs but cannot see one which does autocropping at all and there are hundreds out there! Thanks.
