Sampling rates all wrong - how can I change them??

[venomm]

Hi, I am really stuck here and I hope someone can help?
I have searched many posts on the forum, but cannot find the exact answer I am looking for:

I want to join together/merge 2 avi files to make one file. However, the 2 avi files I've got have 2 different sampling rates (according to my Joiner program). I attempted to alter the format of both to an MPEG 2 and then tried to merge them to no avail.
The CBR of 1 is 2000kbps and the other one is quite a lot higher than this - according to TMPEGEnc Plus.
Is there an EASY way - I am VERY much a learner here - to change one of the files, or both, to the same Sampling rate so I can merge the two files, please? Is there a program which will do this for me - freeware is very preferable!!
Both avi files play well on their own, but seem incompatible when I alter the format and then try to merge them into one. I want to make them into one DVD eventually so I can have and view them together.

hi and welcome to the forum,
i think your problem is not the sampling rate, but more a different resolution of some kind!

i got three different suggestions on how to merge them/create your dvd! in no particular order:

a) create 2 seperate dvd compliant streams, and author them so they play on after another!

b) use avisynth to load both avi files, crop and resizes so they have the same resolution, append them in avisynth, then frameserve to your favourite mpeg encoder!

c) use virtualdubmod to do the above described tasks, then encode to huffyuv avi (to prevent extra quality loss) and encode this huffyuv avi with your mpeg encoder!

i'd personally do it the a) way :)

Thank you for the reply - I will have a go at both a) and b) - c) seems a little technical and beyond me at the moment. Keep your fingers crossed!!
Cheers, V

Here's the way I finally managed it - and I learnt something new about Mainconcept too!!

In this situation I did not join the avi files, I just set up the encoder to encode to mpeg2 (finally to DVD) then added each project to a batch list and encoded them to 1 file.
I used MainConcept for this but I was told TMPEGEnc might have this option as well.
I hope this helps anyone else with the same problem(s).
