I've been transferring files & editing collaboratively using Google Drive on the cloud in tandem with the Google Drive app that syncs files to a local hard drive. I started off with $10 bucks a month for 1T but then cancelled it after my university provided unlimited Google Drive space (reason enough to consider returning to school). Now I use the Google Drive app on my MAC to edit and sync files with AVID Media Composer & Final Cut Pro. Each editor has their own sequence for cut comparison with a master sequence containing final edits. After you cut using the local Google Drive app, it automatically syncs in the background to the shared version on the cloud. The only thing to watch for is that two editors don't simultaneously edit the same sequence. Running off a screener for comparison viewing or to send a client is ez pz as well. Welcome to the new world of collaborative video editing on the cloud! This new trick is a game changer for an old dog like myself.
