Testing Guidelines and Uploading Instructions
Prior to sending content for distribution, all new clients must send test files for QC analysis and approval. This allows us to perform and communicate our quality control procedures and attend to all potential issues ahead of time. After testing is complete, we can setup customer specific FTP login credentials for live orders. The goal of the testing phase is to develop a repeatable process that can be automated to accelerate distribution.
