How to join 2 different format avis?

[Hibbs]

I have two AVI's I wish to join. Virtualdubmod tells me that they are different formats and cannot do it. How do I process one to be the same as the other, in particular what properties must be the same?

Frame rate and aspect of 02 has been adjusted to that of 01.

Thanks, Hibbs.

Your going to have to encode one avi to be like the other. It looks like your resolution is different between the two, plus the audio bitrate on one is variable while the other is constant. I'm not sure if that is a problem but I think it is.

Hi!

The video bitrates are different as well.

I'd suggest you start from scratch with your original source material and create only one video.

BTW - Why did you use two different versions of LAME?

[Hibbs]

These two files are a 2 part tv show from different sources, hence the differences. I made all properties the same using avifrate and xvid4psp. Virtualdubmod joined fine. Audio synch was lost in file 02 for some reason. I'll try another attack.

Thanks for your input.

[Hibbs]

After reprocessing the two originals with Xvid4PSP I now have what appears to be two identically formatted files. I cannot see any diferences when viewed with GSpot and MediaInfo. Neither VitualDub, VirtualDubMod nor AviDemux will let me join them. What gives?

VitualDub gives the attached error.

Where did you get the AVI source files?

A curious question until I read your forum rules. Consider the thread closed.
