Thread: What does Blu-Ray movies do that DVD's do not?

I for some reason thought Blu-Ray movies are supposed to be like imax in your home and i was very mistaken!!!! What is the benefits of blu ray?

Wow there’s a lot of misinformation here.

1)Blu-ray CANNOT store 1080p movies at 60 frames per second because it’s not in the specifications so Blu-ray Disc players would not play such a disc, only PS3 games run at 1080p60 on Blu-ray. For 1920x1080 resolution Blu-ray can store 1080p24, 1080p25, 1080i50 and 1080i60. Only 720p encodes can run at 60fps on Blu-ray.
2)What is 1948 standard def video? DVD’s when encoded to match DVD-Video specifications can carry NTSC which is 480i60 or PAL which is 576i50.
3)The best sound on DVD is full bitrate dts which is 1.509 Mbps vs 5.1 DD which is only 448 Kbps maximum.
4)HDTV spec isn’t 1080. That doesn’t make sense.
5)Blu-ray discs aren’t computer programs, the menus are written in BD-Java and overlays in picture-in-picture use BD-Java, however the video is encoded using one of three video codecs similarly to DVD, the latter using only MPEG-2 while Blu-ray also allows the two newer codecs VC-1 and AVC/MPEG-4.
6)Blu-ray Discs can carry 8 channels of uncompressed audio, not 6. Blu-ray supports up to 24/96 7.1 audio and up to 24/192 5.1 audio uncompressed. DVD supports up to 24/96 5.1 compressed via dts 24/96 codec (lossy) or on DVD-Audio discs as MLP lossless compression. DVD-Audio discs require special DVD-Audio players.

In a nutshell Blu-ray offers 6 times the resolution of North American DVD’s and high resolution audio that works in every player. 3D Blu-ray spec allows for the newer MVC/MPEG-4 coded predominantly designed by Panasonic which supports 1080p24 for both eyes (1080p48) with the left eye channel being the dominant channel (1080p24) usually backwards compatible for 2D players.

DVD
Audio – Dolby 5.1 448 Kbps or dts 6.1 1.509 Mbps (but usually ½ bitrate 756 Kbps)
Video – 480i60 or 576i50 using MPEG-2 codec with peaks up to @ 8 Mbps

Blu-ray
Audio – Uncompressed PCM 24/192 5.1 up to 27.648 Mbps, dts-ma or Dolby TrueHD up to 18+ Mbps
Video – 720p60, 1080p24, 1080p25, 1080i50 or 1080i60 (as well as 480i/480p/576i/576p) using either MPEG-2, VC-1 or AVC/MPEG-4 codecs with peaks up to @ 40 Mbps.
3D Video – full 1080p 3D using MVC/MPEG-4 codec, same bandwidth limitations. Codec is 50% more efficient than AVC/MPEG-4.

Also Blu-ray allows for BD-Live, proper picture-in-picture where two separate streams are mixed, two separate audio streams mixed, interactive menus, etc.

For PC storage there are already specifications set for 100GB discs and higher. DVD for PC is still limited to dual layer DVD9’s.
