Trim an AVI using direct stream copy (closer than keyframes)

[Dili]

i'm looking for a way to trim an avi, preferably an xvid/divx mpeg4, using direct stream copy with more precision than keyframes (so forget virtualdub's editor). i'm pretty new to AviSynth scripting so any help would be appreciated.

here's what i have so far with an xvid avi:

# Created by AVSEdit
video = "clip1.avi"
AVISource( video )
trim( 500, 1000 )

when i open it in virtualdubmod, the trim is perfectly fine but it loads the video as yv12 and the audio as pcm. now i know i'm obviously missing code in my script cause AVISource's pixel_type's default is yv12 and the only other types are yuy2 and uncompressed rgb. as for the audio, the only method i know is WAVSource but that will obviously load the audio as pcm.

i searched the forum for this topic but to no avail so if anyone has any suggestions i would appreciate hearing them. also if i somehow missed this topic somewhere on the forum please direct me to it.

thanks!

AVISynth serves up raw video and audio. There is/was a DSynth mod, however that doesn't get you out of the fact that you can't cut on a non keyframe. You need to re-encode at least the last section before the cut, the rest you can directstream.

heh i had a feeling it wasn't achievable the way i wanted to do it.

oh well! i'll just have to work around it.

thanks for your help celtic_druid!
