AAC Audio cut short??

AAC file (2 channel)......It's supposed to be about 1.5 hours, but it gets cut off at about 50 minutes. Tried 3 times, erasing the peak file each time.... same outcome. Vegas sees the correct overall time as can be seen by the length of the T/L.

It was tested in PP and works fine so it's not a corrupt file. This is vegas 9e 32... the 64 bit does the same thing

Any ideas?

Render it out of Ppro as .wav, bring back into Vegas.

Yeah, that's my work-around... but the question still remains.

I just had a further look at this. Don't know if I'm having a seniors moment or what, from what I can see Vegas doesn't directly support AAC. It'll render H,264 with AAC audio but I can't find anyway to create an AAC audio only file.

Mine was AAC audio only

Make sure you have quicktime installed

I have found a bug confirmed by tech support when rendering to Sony AVC/AAC which may be related to your problem.

When the bit rate of the AAC is set below 80 kbps for some or all sample rates you get output like yours or with other failure modes depending on the bit rate you select. The Main Concept AVC encoder does not have this problem.
