E NCODING A UDIO A ND V IDEO 4-5VBR vs. CBRVBR (Variable Bit-rate) encoding and CBR(Constant Bit-rate) encoding are two options forencoding video. Bit rate is the speed at which thevideo, audio, and interactivity stream off the disc.The maximum rate is 9.8 Megabits per second.CBR encoding allots the same number of bits perscene through the entire encode. With thisprocess, you can fit about an hour of video on a4.7 GB disc.To get more video in the same amount of space,VBR encoding is used. The VBR encoding processallots only as many bits per scene as is needed.The amount needed is based on an analysis passof the source video where the encoderdetermines what content is difficult to compressand what is easy. The result is a lower averagebit-rate, but the same high quality. With VBR, youcan get about 2 hours of video on the same4.7 GB disc.7 In the Encode Setup window, select New Audio Set from the AudioSettings list.
