My next project I have several VFX people (about 4 or 5) who will need to work on the footage once I edit it. We're shooting in 4k and this will be my first time dealing with files sizes this huge. All of the VFX people are in different locations (out of state and out of country). What is the best way for transferring files since online will probably not work since I'm imagining the files will be well over several GB's?
