VBR audio stream detected

[calhoun]

I have downloaded some DivX and Xvid videos which I want to re-encode (make smaller) but when I load them into virtualdub I get the above message. It goes on to say that virtualdub has detected an improper VBR audio encoding in the source AVI file.

What is this all about?

Whats the best way to re-encode these videos with "improper VBR"?

Thanks in advance guys.

What it is about that the avi container wasn't designed to hold vbr audio, it was hower "hacked" to do so which Avery Lee, the author of Vdub doesn't agree with, hence the message.

If you use VirtualDubMod, then it will let you keep the VBR header. If you want to seriously shrink the files though I would suggest using he aac. If you want to keep using avi then you can mux it using AVIMuxGUI.

Although if vbr mp3 is a hack then he aac is surely an even worse hack.
