HD Encoder Quality Compared Side-by-Side
A Technical Presentation and Demonstration of Video Clarity's Viewstore Visual Analysis System

We've all thought it would be fun to do it, but only a handful have ever had the opportunity to really sit down and visually compare one HD encoder's quality to another. Sure, you can watch one result and then watch the other. But to really compare one result to another visually, you must see them side-by-side on display devices that are identical; or on a single display device able to play side-by-side real-time, uncompressed HD video to the same display device. That's exactly what the Viewstore Visual Analysis System does. Not only can you watch two decompressed video sequences on the same display device at the same time, but you can also zoom, pan, jog & slow-mo the live videos to view even greater detail. And that's what we're going to do at this month's SMPTE/New England Meeting.

Those in attendance at National Boston Video Center saw a live demonstration comparing several different video/file formats of varying material that's been encoded at different parameters and projected as a single split screen image using a JVC DLA-HD2K Hi-Definition video projector.

A technical presentation on the workings of the Viewstore Visual Analysis System was featured part of this presentation.
