What platform are you using? Desktop or Mobile?
For desktop, at least for me, I couldn't access Google Drive photos until after I installed the Backup and Sync Google Drive app and then in Rush when I go to add footage to my project I go to Media Browser and under the subheading "Cloud" I now have Google Drive.
I checked my Rush app on my iOS app and didn't see Google Drive listed, so I've not been able to figure that one out.
I can confirm Gerik's suggestion about the desktop. You can download the backup and sync app here: Download Backup and Sync - Free Cloud Storage
Once you've downloaded it and set it all up, open Rush and you will be able to see Google Drive in your media browser under "cloud." This works because it's your Finder/File Explorer finding the Google Drive content, not Rush itself.
Google Drive is not yet supported on the iOS app but the plan is to support more platforms soon. For now, the workaround is to download files from the Google Drive app to your camera roll and import from there.
Is Google Drive supported on the Android app? Doesn't seem to be a way to get the app to recognize that service. Any assistance would be appreciated.
Thanks for your interest in Premiere Rush.
Google drive support is available only for Rush Desktop so far. We are still in the process of adding its support on mobile devices, both on iOS, and Android.
