When you try to export to a QuickTime format from Adobe Media Encoder on a Mac, the application becomes unresponsive.
This issue occurs when exporting to an NFS volume from a system running Mac OS X 10.x.
Note: Although you can close Adobe Media Encoder, it's necessary to restart your system before AME can export properly.
In some cases, it is possible to work around this issue by changing the mounting parameters of your network volume. Enter the following command in the Terminal application:
sudo mount -t nfs -o rw,resvport,sync,soft,intr,bg your.server.here.com:/ifs/data ~/Desktop/nfs
This issue is exclusive to NFS-mounted volumes on a Mac. Changing the mount to SMB avoids the issue.
AME supports some QuickTime codecs natively. Those codecs do not exhibit this behavior.
If none of the above solutions resolve the issue, export to a folder on your computer and then manually copy the file to your network volume.
