new help with muxing/demuxing

[mridang_agarwal]

I havent tried to mux/demux files before and am really confused about how to do it. I have a few VOB files that i need to demux -> edit -> remux. I downloaded ReJig to demux the VOB files. I demuxed the file and got two files XXX.AC3 and XXX.M2V. What is the m2v file? Now i need to edit the video with AVISynth? I have created an AVS script and i wrote

AVISource("C:\XXX.M2V")

But when do this i get an error. How do I do this? I then need to remux th files. Which tool shoudl i use? Can i use Rejig for remuxing?

M2V is "Mpeg2 - Video". You can't load it with AVISource since it's NOT AVI!

i have to crop and resize a portion of the VOB video, so how do you suggest I go about it? If I were to use AVISynth, what would i have to do to the VOB video?

I've scoured google for information and found a way to crop and resize the video. It seemed really simple - its right here. It tells me to use TMPGenc but can TMPGenc use M2V and AC3 files??? Why is it so complicted, i mean like, when i had to remove the black bars from a movie, I could do it in a snap suing Dr.DivX, but here its such a lengthy procedure. Isnt there a simple way to do this?

If you aren't editing the file, just cropping and resizing, just work on the m2v file and leave the AC3 alone. You can mux it back in later. Tmpgenc should be able to take an m2v file - it's just mepg2 video.

Try DirectShowSource("pathto\yourfile.m2v").
For resizing theres BicubicResize, LanczosResize, Lanczos4Resize, among others.. Checkout avisynth.org's internal filters list.. http://www.avisynth.org/FiltersByCategory

guns1inger, i cant see an option for MPEG2 in TMPGenc. Its got an option for *.MPG but tell me choose and MPEG1 file.

I found this, and tried to install it but it asks me for quite a few settings such as aspect ratio, GOP, YUV Range etc. Could someone tell me what to choose? The settings are displayed in the attached image file.
