OMF Files Have a 2-Gigabyte Limit
OMF files that you create cannot be larger than 2 gigabytes. In most cases, this
should not present a problem because 2 gigabytes will accommodate approximately
7 hours of mono audio media (depending on the bit depth and sample rate of your
audio). If your sequence exceeds this limit, you will see a warning message before
exporting begins.
