Blu-Ray Authoring

DUB hub makes it easy to get your content onto Blu-Ray. Blu-Ray discs fit more, and do more than traditional DVD. Blu-ray discs provide much greater data storage capacity and faster bit rates than standard DVD. Translation: much improved picture and sound quality.

The DVD format was certainly a huge leap compared to VHS tapes, but it has major shortcomings as an entertainment medium for the high-definition era. DVD's compression scheme and disc structure were designed for standard-definition video. As TVs have grown bigger and better, the limitations of the DVD format have become more apparent. When watching DVDs on some of the better 1080p HDTVs with screens of 50" or larger, compression noise and artifacts are sometimes noticeable. Blu-ray, on the other hand, offers 1080p resolution for an incredibly smooth, detailed picture.

HD's much higher level of picture detail requires much more information. So, any high-definition format requires much higher data storage capacity (measured in gigabytes). Here's an example: a digital recorder with a 250GB hard drive can store about 200 hours of standard-definition video, but only about 30 hours of HD video. HD's superior picture quality also requires much faster data transfer rates (often called "bit rates") from the player to your TV (measured in megabits per second — Mbps). If the flow of information from a DVD player to a TV could be characterized as a babbling brook, the flow from a high-definition player would be a roaring river.

Blu-Ray Encoding

There is no data difference between a processed duplication and a glass mastered replication disc. In fact, both processes extract the information from your master source in EXACTLY THE SAME WAY. Other than the way your disc is manufactured, - the biggest noticeable difference between a replicated CD / DVD disc and a duplicated CD / DVD disc may be the way the surface is marked. This is usually due to the cost restraints associated with the method chosen to process the order.
