Merging different kinds of videos

[Lincoln Burrows]

I am not sure where to ask this question, please help me on this.

I have dozens of different videos, using all kinds of containers/codecs, not only for video but audio.

For example:

1) Videos using different resolutions and aspect ratios - some are 4:3, others are 16:9, and a few are using a wrong original aspect ratio, as a result of the original encoding (not sure how I fix this);

2) Videos using DivX, XVID, etc.

3) Videos using MP3, others AC3;

4) Different containers, like AVI, MPG, WMV, etc.

All I want is to MERGE ALL KINDS OF VIDEOS into a single file, using the best configs to have the most successful results in terms of enconding, since we will have a little loss in image quality anyway by doing this.

And no limitations on the filesize. I am not sure who told me that, but it seems that AVI files can't be too big or can't deal with all kinds of codecs properly.

So,

a) what's the best software to do this job;
b) What kinds of settings do you recommend?

Hi!
a)Avisynth
b)each thing at its time, append and prepare all the videos will certainly be a long work, codec settings can wait
c)To be more precise, I wait your answer at a question which will certainly follow...

Hi!

Of course, you're joking, aren't you?

Hi!

Of course, you're joking, aren't you? Hmm, no? :p

VirtualDub can't do this job, it's not accepting different kinds of videos to be merged... Will Sony Vegas do that with no hesitation?

The other day for example, I attempted to extract a small piece from a FLV video and the conversion introduced some bugs (it was done by Ultra Video Joiner). Audio out of sync sometimes, video slower than the original source...

This is something else that I forgot to mention - finding the best softwares that can "cut" those videos in the exact places ignoring keyframes already set.

Usually when you do that (following the keyframes means you won't be able to cut frame by frame, for example, a keyframe can last from 05s to 11 seconds, and you need to cut the space between 02s and 07s to use that piece on the unique video mentioned by this thread), you use a setting called direct stream copy (no reencode). Ignoring keyframes will require you to save those files uncompressed, I guess no reencode involved.

VirtualDub, as far as I can tell, can't do that for all kinds of videos... *

EDIT: One of them can do that job perfectly for MPEG-2 videos:

MPEG-VCR, as recommended here (http://club.myce.com/f32/software-edit-mpeg2-files-80771/).
