Avid Pro Tools 2020.5 update: New cloud features & bug fixes

Avid recently announced the Pro Tools 2020.5 update (last updated May 21, 2020), where users can find new preferences that expand upon existing cloud based synchronization services. Additionally, some previously existing bugs have been worked out.

New Features in Avid Pro Tools 2020.5 Update

Cloud Storage Services

Cloud computing has become a game-changer for creators, with services like Dropbox, Google Drive, and Microsoft OneDrive freeing collaborators from physical constraints, increasing productivity, and enriching workflow. In 2016, Pro Tools 12.5 saw the highly-anticipated incorporation of such services within the DAW, allowing for cloud storage and simultaneous remote collaboration. A “session” which would then need to be converted to a “Project” in order to be accessible on the cloud. Since then, the preferences for these services have undergone a few upgrades to encourage as efficient a collaborative workflow as possible.

Prevent Others from Overwriting Open Session

With the new Pro Tools 2020.5 update, there will now be a “Prevent Others from Overwriting Open Session” preference, which when enabled, will allow for multiple users to work on a session in a synchronized and shared location. While the session is open, a temporary file gets created next to the session file, and any other user is denied the ability to overwrite the project directly, notified instead that the session is currently open for someone else. They can, however, “Save As” a separate file if they so desire. Once the original user closes the session, the temp file will be removed, allowing other users to open and save over the session once again.

I recommend enabling this option if, within the group of collaborators, it is deemed most appropriate to work individually on the same project at different times, without one collaborator’s edits getting in the way of another’s as they are working.

Keep Unused Folders on Session Close

By default, Pro Tools removes unused folders within your session folder.  You can enable the “Keep Unused Folders on Session Close” preference with Pro Tools 2020.5 update to keep your folders safe from automatic removal once the session gets closed. Enabling this preference also prevents additional synchronization options.

Local Waveform Cache Versions

The existing “Local Waveform Cache Versions” preference will now work with sessions on drive shares when “Prevent Others from Overwriting Open Session” is enabled. The Pro Tools 2020.5 update also helps to significantly lower the amount of syncing operations. This preference determines whether or not copies are stored locally for sessions in network-storage.

If you are not concerned about losing any hard drive space, I would recommend creating a local copy of Waveform cache to facilitate the start-up process of any sessions you have saved on network storage. When waveform cache is stored locally, the rendering tasks which occur when opening a session are greatly sped up.
