Blu-Ray DVD Standards
My previous post covered “standard” definition DVDs, which are pretty low res in terms of computer displays. Blu-Ray DVDs are basically High Def computer monitor specs. So if creating a video from a PPT presentation to go onto a Blu Ray DVD, it is the same process:
– Export at highest quality PPT offers of 960x720px (which is below Blu-Ray specs, but the best natively available)
When authoring a Blu-ray DVD, that software will upconvert (ie. make larger) to Blue-ray HD quality:
– 1920 x 1080 (1080p) resolution
– Audio can be Dolby TrueHD or DTS-HD Master Audio and support up to surround sound 7.1 (at 96kHz/24bit) or 5.1 (at 192kHz/24bit)
– Maximum bitrate of 40.0 Mbit/s
Blu-Ray Trivia:
– The name “Blu-Ray” is because it uses a blue-violet laser to read/write discs.
– Blu-Ray has its own association, the “Blu-ry Disc Association” or “BDA” – which is the group of consumer electronics, media and computer manufacturers that established the technology standards.
– A single layer Blu-ray disc can hold 25GB of data (standard DVD is 4.7GB) and a dual layer can hold 50GB! But that is only 4 hours of HD video (on a single layer disc).
