I sort of remember running into this problem years ago, and what was figured out was for a file that will ultimately be 95GB you need to have double that free. So 190GB. The thinking is that it's first building a hidden/invisible swap file, and then from the swap file makes the final file. So you need double the space. It's crazy. And I'm probably totally wrong and just remembering some old wives tale.

After many crashes with a disk full error after about an hour of exporting I cleared off a 325 GB drive and exported to that. Finally it worked but the resulting file is only 95GB. All the volumes I had been exporting to with the crashes had at least 135 GB free space. After finally getting a successful export to a drive with 320 GB free I had to reexport a 2nd version to the same drive which then had 138GB free. I figured since my first export was only 95 GB and the new export was only an addition of 4 seconds of black at the end I figure it should be no problem. I also made sure to leave the computer alone and not run Avid during the export but it crashed again. I then exported the new file to a empty 325GB drive and it worked and the file was 102GB. So
> why is QT Pro crashing saying disk full -34 error? Is QT Pro trying to grab a bunch of space because it doesn't know how big the file will be? I remember FCP etc... use to have a problem where during certain operations it would try to commandeer all the space on the drive and would sometimes give false errors because of this. Could I be seeing some remnant of this. Curious what others think.
