how do you edit out commercials in mpeg2 caps?

i capptured a program with ati's tv proggy, but i dont want all the ads in there. is there anything i can use to just edit out the ads without recompressing? i capped in all i frames. i also read that tmpeg can do the no recompress part, but i dont think it's accurate for looking through frames, is it?

AFAIK, there is no software that can cut MPEG-2 files 100% accurately, due to the nature of MPEG files: the frames aren't encoded separately as MJPEG for example. So TMPG is the way to go, cut at the place you want, and hope that it will be as accurate as possible.

12 seconds?! that much?! I was talking about +/- 2 seconds, but not 12. I'm a bit surprised. Are you sure you have the latest TMPG version?

i have version TMPGEnc 2.58.44.152. thanks for the quick replies but i am almost done converting it into a huffyuv avi. i'll leave it overnight to compress to mpeg-2. 2 seconds is still too much for my liking though.

Why do you convert them to avi? VirtualDubMod can open MPEG2 files. You can cut them there and then frameserve the video to tmpgenc

i can edit them the vid exsctly where i want in vdub. doesnt frameserving only do video? no audio?

It delivers audio and video.

thanks, i am looking into this now. do you have any links on what to do? i haven't played around much with frameserving.

If you captured in all I-frames, then you should be able to edit it easily. You should lose a lot less than 12 seconds! There is a program called M2-edit Pro that works really well, and you won't have to re-encode and lose quality. Unfortunately it is expensive, but they may have a demo version available to try. It's worth looking into, and if a trial is available, it would save you a lot of time and quality. cjv

i am dl'ing a demo now. thanks. also, the vdubmod proggy gave me an error for my mpeg-2 vid, does not contain video stream. funny how i can play it in media player. :confused:
