Templater works with Adobe After Effects running on either Microsoft Windows or Apple OSX operating systems.
It is compatible with Adobe After Effects versions CS5 and later. See system requirements for specific Adobe After Effects versions at adobe.com.
Internet connection is necessary for activating some features, validating edition features, using cloud-based footage sources, and using Google Sheets documents as data sources.
To use Google Sheets documents as data sources, your system must be able to reach your Google Drive account from within your local network. Ensure that any firewall on a machine running Templater does not block Google's servers.
