Image Quality in FootageQuest, an Online Footage Archive

Image quality considerations played a major role in the design of FootageQuest, a portal for on- line sales and delivery of footage. Multiple suppliers with various source material required us to create a single standard so end users would receive consistent quality. Since many customers selected clips from various sources and wanted them all delivered together in one order, we needed to optimize to support these composite orders. We decided that it was easier to build these compilation tapes from a digital server than to use multiple tapes to build a single fulfillment tape to send to the customer. Our goal was to determine what bit rate, digitally compressed, would give the same results as tape. Extensive testing led us to this result: 50 megabits per second, using the PQA200 Picture Quality Analyzer from Tektronix, ga ve the best results.
