How much video can fit on a Blu-ray disc?
As with DVD, this depends on the usage of video bandwidth, the number of audio tracks and other authoring criteria. Furthermore, the choice of the video compression format also impacts playback time. On average, a 25GB Blu-ray disc can hold 135 minutes of HD video using MPEG-2 compression format plus 2 hours of bonus material in standard definition quality or 10 hours of standard definition video. A 50GB Blu-ray disc can store approximately 3 hours of HD video plus 9 hours of standard definition bonus material. Using any of the advanced video compression format, these numbers can be significantly increased.
