As experts in the film and media industry, we are advocates of 4K Blu-ray. Ultimately, Ultra HD physical media is the best quality entertainment and here we explain why. We’ll start by answering the following questions:
- What is Blu-ray?
- How does the quality of Blu-ray discs compare to DVDs?
- Why 4K Blu-ray?
- Choosing a Blu-ray/4K player
What is Blu-ray?
A Blu-ray disc is an updated version of a DVD disk and essentially stores high-definition images and promises a better image than standard DVD disks. It is important to play a Blu-ray disc on a Blu-ray player to ensure the quality and same applies to UHD discs. Playing a Blu-ray disc in a standard DVD player does not tend to work, however, Blu-ray player can also play standard definition discs.
How exactly does the quality of Blu-ray compare to a DVD?Based on the look of the Blu-ray disc, you wouldn't think there was a big difference between the disc itself and a standard DVD since they are the same in shape, size and general appearance. However, when you investigate the make-up of the Blu-ray, you’ll discover that there are many advantages to choosing Blu-ray over standard DVDs. Here are just a few technical differences between the two different disc formats:
1. A Blu-ray disk has a much larger storage capacity than a standard DVD
A Blu-ray disc can store up to 50GB of data which is essentially 10 times the capacity of a standard DVD. While a single layer DVD stores just 4.7GB of data and double layer (DVD-9) stores up 8.7 GB of data, single layer Blu-rays store 25GB of data and double 50GB. Essentially, in real terms, 50GB of data is enough storage for 4 and a half hours of high-definition images and 26 hours of standard definition data.
2. Blu-ray discs are more scratch resistant
There is nothing worse than getting three-quarters of the way through a movie and then it starts jumping, pausing and buffering until you need to turn it off. With Blu-ray, this is far less likely to happen than with a standard DVD. This is thanks to a thin, yet scratch resistant, coating that is more effective than the coating on standard DVDs.
3. Blu-rays run off blue lasers, instead of red lasers (hence the name!)
Why is this significant we hear you ask? Well, blue lasers are shorter and closer together than red lasers so provide more accurate, and detailed, sounds and images.
Why 4K Blu-ray?
4K Blu-ray is ultimately the next step of the Blu-ray hierarchy, offering a further improved visual image and Ultra high-definition.
Essentially, you can’t get better than the 4K Blu-ray disk in the current movie market. Perhaps, in future, the technological brains out there will develop an even greater picture, however, for now, we’re all raving about 4K and rightfully so.
Trust us, when you’ve gone 4K, they’ll be no going back!
Choosing a Blu-ray/4K Blu-ray player
Standard DVD players cannot play Blu-rays which means that when you are buying a new media player, you’re best opting for Blu-ray. And, since 4K offers the best quality, a 4K Blu-ray player is your best bet but you would need to invest in a 4K TV as well in order to watch it. You can take a look at this What Hi-Fi? that can provide further information on choosing the right Blu-ray player for you.
