Howdy, and yes some elements of the video submission guideline document is out of date. Fully expect a revised version up there soon.
No proxy uploading is required. Upon approval as a video contributor you will be required to open an ESP account. ESP! What is that?? Glad you asked. ESP is our proprietary video content uploading system designed to facilitate mass uploads of video content. It is further designed to facilitate faster inspection and activation of content.
 
Also at one time it was required to upload documentation with all CG work uploaded for inspection. This was required due to our obligation to protect any proprietary content of motion graphic and visual effects artists, CG model designers and software developers and to protect contributor and client alike from infringement claims. This documentation is no longer required for all uploaded content however, when video content inspectors are presented with possible problematic files, we will ask for clarification from the contributor.
