No uploading.
Its now possible to have truly cloud based rendering services which don't require you to upload your files to a render farm company. It can all be automated through the new Deadline 10 cloud portal using AWS.
You can request an amount of machines [of varying specifications] relevant to the amount of render engine licenses you have, then submit your job as you would normally through Deadline render. The scene files are uploaded and the finished renders automatically downloaded without you physically doing anything.
Below is a quick animation test, we sent off 250 frames to the AWS render farm. Took around 25 minutes / frame with 6 machines... Oh, this is rendered @ 2500 x 1406 resolution.
Results.
Bloody marvellous! Quite expensive at the minute though, about the same as using a cloud render farm... but its way more useful when you are up against it.
