Do you mean "capture" or "import"? I'm importing AVIs all day?
The AVI is only the "wrapper" for the file. It is what is inside it that makes the difference. I could add an extension to a file such as
Myfile.bum - but it would still be a MP4 or DivX or MPG - depending on what made it.
Having the extension is great to tell s/w what NEXT to do - maybe! If I decided to use "*.bum", and in actual fact it was a WMV file, I would then have to instruct windows to use the extension to fire-up Windows Media Player. So, I don't! I keep to the convention.
Get GSPot and get back to us and tell us what is inside this "AVI".
Need to know more? Sorry .. .
Grazie
