General Compatibility
Pro Tools 12 does not support video capture (PTSW-181456)
Pro Tools 12 does not have the ability to record video to the timeline. Co-install Pro Tools 10.3.10 (or higher) on the same system and
use an Avid Mojo SDI to record video into Pro Tools 10. The captured video can then be used in Pro Tools 12.
Pro Tools 12 does not allow import of WMA files (PTSW-181506)
If you attempt to import a WMA file into a Pro Tools 12 session, Pro Tools cannot convert the file and posts a “file is unreadable”
message. Co-install Pro Tools 10.3.10 (or higher) on the same system, import the WMA file, and convert it to a format supported by
Pro Tools 12.
Pro Tools 12 sessions that use more than 4 gigabytes of RAM will cause Pro Tools 10 or lower to quit unexpectedly
(PTSW-181963)
If you attempt to open a Pro Tools 12 session that uses more than 4 gigabytes of RAM in Pro Tools 10 or lower, Pro Tools will quit unexpectedly.
To open such sessions in Pro Tools 10 or lower, first reduce the amount of session RAM usage to less than 4 gigabytes in
Pro Tools 12 by removing virtual instruments that take up system memory.
OMF files that contain video are not compatible with Pro Tools 12 (PTSW-184397)
OMF sequences that contain video cannot be imported into Pro Tools 12. OMF sequences that contain embedded or referenced audio
files can be imported into Pro Tools 12. To import a sequence that contains video media, use a linked AAF sequence.
Pro Tools session file formats version 4.x and lower are not supported in Pro Tools 11 and higher (PTSW-181049)
Pro Tools session files from Pro Tools versions 4.x and lower are not recognized in Pro Tools 11 and higher. In the Pro Tools Workspace,
these files are listed as “unknown,” and cannot be opened. Co-install Pro Tools 10.3.6 (or higher) on the same system and open
the session files in Pro Tools 10. Save the session in the current Pro Tools session format, then open the session in Pro Tools 12.
Automatic Update Notification will not connect through a proxy server that requires authentication (108837)
Software Updater will not find an active Internet connection when behind a proxy server that requires authentication to gain Internet access.
To work around this, the client machine with Software Updater needs to be moved out from behind the proxy, or the proxy needs
to allow HTTP access via port 80 without requiring authentication.
Aero causes errors at lower HW Buffer sizes (103563)
With Aero enabled in Windows, Pro Tools will not play back without errors at HW Buffer sizes of 128 and below. Turn off Aero if you
want to use lower HW Buffer sizes.
