X264/MP3 128 Video - need to cut out just a portion without re-encoding it

i have a avi that is a x264/mp3 encdoded piece. i want to show some people the quality of x264 so i would like to cut out a 10min piece of the movie. i do not want to, in anyway mess with the qaulity, just kind of a cut and then save type of deal. can this be done?

thanks in advance,
bob

Tried with virtualdub yet?

honestly i haven’t tried anything. i wanted to know exactly what would work instead of spending hours with stuff that doesn’t. does virtual dub do this?

What is the problem of trying it??

forgot to post - got it done with Avidemux v2.1.2 :smiley:
