With the continuous upgrade and development of digital video, people now have higher requirements towards the visual experience. To many people, Blu-ray discs look exactly the same as DVDs in both size and shape, and also their functions. But by comparison, Blu-ray seems to provide a better quality than DVD. So what are the exact differences between Blu-ray and DVD?
In fact, there are many differences between Blu-ray and DVD, for example, in storage capacity, image resolution, digital audio, player compatibility and 3D compatibility. For these differences, the general public still has a lot of confusion.
So what's the exactly differences between DVD and Blu-ray? Which one is better to choose? Now, you can check out the analysis below.
Part 1. The Differences Between Blu-ray and DVD
Both Blu-ray and DVD are a disc to store the media files with higher quality and larger sizes. DVD is an old format, Blu-ray is a new high definition format, which has some improvements compared with traditional DVD. Here we compare Blu-ray and DVD from five aspects.
Blu-ray disc uses a blue laser beam with a wavelength of 405nm to read and write content, while DVD uses a red light reader with a wavelength of 650nm. A single-layer DVD usually has a capacity of about 4.7-9.7GB, while a single-layer Blu-ray disc has a capacity of about 25 or 27GB, which is enough to record a high resolution movie for up to 4 hours.
Compared with ordinary DVD, the most popular feature of Blu-ray is its HD resolution. This is also the biggest difference between it and ordinary DVD disc. The lowest resolution standard of Blu-ray disc is 1080p. Now there are many Blu-ray discs on the market that have reached 4K. By comparison, DVD only supports the 720p standard definition image, so Blu-ray has better quality than ordinary DVD disc.
The audio of Blu-ray can realize high fidelity and surround sound at the same time. Moreover, the Blu-ray player can decode the DTS and Dolby of disc, plus 5.1 channel, 7.1 channel or digital optical fiber and coaxial interface, which can truly reproduce the original sound of film and television. These make DVD DTS5.1's high compressed audio less competitive.
At present, all Blu-ray players in the market can play standard DVDs, but the Blu-ray discs cannot be played using standard DVD players. The reason is that the red laser used by the DVD player is too large to read the tiny grooves on the Blu-ray disc. The price of Blu-ray original disk is relatively high, which is also not conducive to storage. Therefore, to play Blu-ray discs, you need to purchase the specific Blu-ray player hardware.
In theory, 3D movies can be recorded into DVD after compressing the video quality, but the film quality is not as good as the original Blu-ray 3D movies. Now almost all 3D movies are only recorded and saved on Blu-ray, and the 3D Blu-ray needs hardware to meet the original conditions by virtue of 3D glasses, Blu-ray DVD player and high refresh rate display.
Through the above comparison, I believe you should have a preliminary understanding of Blu-ray and DVD disc now. Is it to discover the benefits of Blu-ray. So the problem is that the Blu-ray player can only be used at home is not convenient. If you want to watch Blu-ray movies on any portable device, you can choose to rip them into common video formats, such as MP4, MKV, MP3.
