user7996: I'm working with a team, we make some review videos for automobile/cars. There are in-car shots with 3 way multi-cam scenario, sometimes 1 out-car shot may come.
We have 3 producers. There is no strong work of compositing right now, just video editing. However editing is very complicated, sometimes there may be 10 cuts over 10 secs. It should also be managed by all producers, however the media is usually over 40 GBs. It is impossible to transfer this data via internet atm, I lastly found out proxy is intuitive for that kind of work.
We need to figure out the best (at least, optimal) way with performance and time aspects, what do you prefer? Only one may render the final work, we have no issue with that. But there should be a way to preview our work (as a project file) to the director.
Some tech stuff:
Videos are basically 2 hours before editing and the final video comes like 30 mins, not more than 45 mins. There are two 1080p cameras and one 720p camera recording at 24.97, 60 fps and 29.97 fps, respectively. Audio is recorded at 16-bit 44100 Hz PCM mono. The audio channels of videos are deleted right after sync.

user2836: With the other problems you have in your current pipeline, I would just transcode your source files to a low quality, low res intermediate proxy.  Have other editors work off the low quality, small size videos and simply replace the proxy in the final render.
There will be some minor losses in this process due to things like color changes and such from the compression on the proxies, but a final color grading pass will counteract that largely and either way, the problems you are going to get from the various frame rates and resolutions far overshadow the very minor issues you'll get from using the low quality proxies.
