bad sound quality on exported avi's
I finally got a chance to play with after effects last night, and after messing around with it for about half an hour I was ready to export my little quick 10 second composition, and the sound quality was awful. It had pauses in it, and a scratching noise like it had a bad time reading it from the original file. My original file was an uncompressed 640x480 avi, with no compression on the sound either, and this was my export setting's also...so it couldn't of been a compression misread or something of the sort.
Well, I didn't really care about it, and went back and messed with some more effects for another half an hour (and man does after effects kick ass, the whole time remapping being able to handle a logarithmic function). And seen I could set the audio field of each video of mine in the composition to best quality (so i did that). I went to export it the second time and it was still extremely sketchy and scratchy. Could the fact I had two video's with sound in the same composition do this?
any clues to how I can fix this would be great
i forgot to add that I didn't change the frequency, the input video had 44100hz and so did my output settings
although video editing is a technical career, there is more artistic skill required for it than logic
