Time vs. bit-rate
A DVD is generally created from movie files stored on a Non-Linear Editing system which are then encoded for use on a standard consumer DVD
player. A standard 4.7 Giga-Bit DVD can record up to 2 hours of video and audio at a bit-rate of 3.5Mbps, lowering the video quality, i.e. lower
bit-rate to 2Mbps and extend the time greater then 2 hours. Wait a minute, what is bit-rate your asking?
Bit-rate is the speed at which the video/audio stream is moving over a time period of 1 second. So then the higher the bit-rate is the higher the quality your video will be. As a example, if we use a 4.7 Giga-Bit DVD to record a 1 hour video project the
bit-rate will double to 9 Mbps, Wow... twice the video quality. A DVDs maximum bit-rate is 15 Mbps.
How to get the most from your DVD
A DVD has a much superior video and audio quality then most other standards like; Broadcast
Television, Cable, or even a VHS tape. Because of the lower quality in these other standards our Television Monitors are usually miss-calibrated to
compensate. Black-Level is the key to a more enjoyable video experience. A higher black-level, a lower brightness-level, and to soften the sharpness
and color controls will vastly improve picture quality when viewing a DVD. |
