Different Sampling Rates-Can't Join AVI[VirtualDub]

[Rainstar]

Hi
I can't join AVI files because their Sampling Rates are different.
-The Frame-rates are the same, 29.970fps
-Am using VirtualDub.
one set are 8000hz and the other are 24000hz

Could someone tell me ,
What is Sampling Rate & How does it play a part in Joining.

This is the error message that VirtualDub Gives:
cannot Append AVI segment. The audio Streams have
differrent sanpling Rates.(1000.00000 vs. 5998.00000)

Any solution?...advice,...information.

Thankyou.

Load iniatialize and use AviSynth to join the two files. The "+" operator does nopt care what sampling rates your videos are.

Hi.

Thanks! Tommyknocker.

-Know what effects these sampling rates have on the joining process ?

Well, obviously, the audio in the two avi's was produced with different sample rates. It depends what you intend to do with the AVI as to wether TommyKnockers solution will be appropriate. I am not sure what would happen with such an avi if, for instance, you tried to re-encode to mpeg with TmpGenc. I have a feeling the audio in the resulting mpeg would be all screwed up.

Use virtauldub to convert the sampling rate of the audio in one avi to the same as the other.

Audio->full processing mode
Audio->Compression-None
Audio->Conversion-> new sampling rate
File->save wave

Now do Audio->wav audio (select new wav file)
Video->direct stream copy
File->Save avi, and save a new copy of the avi

Repeat for second avi and join.

If you intend to re-encode to mpeg, this is sufficient
If you want to save the avi, load the new (joined) avi
Video->Direct stream copy
Audio->full processing mode
Audio->compression (select codec)
File->Save avi

That should do it, bit long winded tho.
