Hi, I need help with a new Proxy workflow for remote editors using premiere pro and Media Encoder.

I just hired a foreign editor to help out on a few large projects, and I am looking for recommendations on a workflow that will keep my team in sync and for creating proxy files that are as small as possible since I will be sending the files over the cloud(Dropbox or Google Drive).

Although I have created proxy files before for remote editing, that was prior to my team filming mixed media(1080p, 4K, different frame rates,etc), and I just used Media Encoder to create small 720p files.

I have looked up numerous tutorials and youtube videos, and they all seem to deal with editing proxy files locally or creating proxies for 4K files. I have also tried to method of ingesting and having premiere pro create cineform proxies, but the file sizes are only about half of the original.

Any advice or suggestion would be greatly appreciated.
