Some shoot contracts include delivering the raw footage on top of the final edit: the agency or production wants to keep the material for later use, another edit, an archive, a dispute. The volume changes everything: you're no longer talking about a few GB, but often several hundred.
Plan for the volume before delivery day
Know in advance how much raw footage you'll need to deliver, and make sure your delivery tool can handle that volume without an artificial cap or an upload that fails halfway through. Nothing is worse than hitting a size limit after hours of transferring.
Structure the files before you send, not after
Sort the footage by scene, shoot day or camera, with consistent naming, before you start the send. An agency that receives hundreds of files dumped together loses a huge amount of time finding its way around, and will remember it.
A delivery that handles the volume without a fragile link
For heavy volumes, a transfer that automatically resumes after a drop avoids starting over from scratch after a disconnection. xFer handles large-volume uploads in parallel and keeps the delivery stable even across several hundred GB, with a private link dedicated to the agency.
In short
Plan for the volume, structure before you send, and pick a tool that handles big transfers without fragility. Raw footage gets delivered like a project in its own right, not just a heavier version of a normal edit.
