It seems that there are no apparent differences between Blu-ray and DVD outwardly, but in fact the differences between them are compelling. If you want to know whether you should buy more expensive Blu-ray titles or not or whether it is the time to upgrade your DVD player to a new Blu-ray player, you’ve come to the right place. Here this article will show you the big differences between Blu-ray and DVD from the aspects like storage capacity, image resolution, video/audio codecs and more. You can also find some DVD/Blu-ray solutions to copy/rip/create DVDs/Blu-rays in this article.
Blu-ray vs. DVD
One of the salient differences between DVD and Blu-ray is the storage capacity. A single layer DVD can hold about 4.7 gigabytes (GB) data, which is the reason why we all it DVD-5, and a double layer DVD, aka DVD-9, can store about 8.5 – 8.7 GB of data, which is nearly twice the amount of DVD-5.
While the storage capacity of Blu-ray is much larger than DVD. Single layer Blu-ray (BD-25) can hold about 25 GB of data, and dual-layer Blu-ray disc (BD-50) stores approximately 50GB of data. The large storage capacity of Blu-ray makes it possible to store more high quality video and audio.
Blu-ray is for high definition display, with its resolution up to 1920 x 1080, namely 2,073,600 pixels; while DVD is a standard definition format, with its resolution as 720 x 480 or 720 x 576 – that’s 345,600 pixels. Therefore the resolution of Blu-ray is exactly 6 times larger than that of DVD. Needless to say, the image of Blu-ray would be sharper, more detailed and more vivid than DVD.
Video and Audio Codecs
DVD only supports MPEG-2 video codec, while Blu-ray also supports MPEG-4 AVC and SMPTE VC-1 in addition to MPEG-2. DVD supports 3 kinds of audio codecs, and they are Linear PCM, Dolby Digital, and DTS Digital Sorround. Except the same audio formats, Dolby Digital Plus, Dolby TrueHD and DTS-HD are also the formats supported by Blu-ray.
Usually the price of a Blu-ray movie is about $5-$10 higher than a DVD movie, but sometimes the price of an older Blu-ray movie is lower than a new DVD movie. Averagely, Blu-ray titles cost more than DVDs, but it is worthwhile to pay a little more to enjoy far better video/audio quality.
DVD player cannot playback Blu-rays, while Blu-ray players in the market now are all backwards compatible to playback standard DVDs, and the video upscaling capability of Blu-ray players would improve the quality of DVD video and make it look better. As for the price of Blu-ray player, mass manufacturing has made it come down, and there are reasonable discounts now and then, so a Blu-ray player would be affordable for most movie lovers.
From the above comparison you can see that though DVDs are cheaper than Blu-rays, Blu-rays can bring people much better video/audio effects. And it would be a great deal to buy a Blu-ray player from a long-term perspective.
