The World of Video Formats and Their Uses

When it comes to enjoying the latest movie releases, enjoying your home videos or just watching television in general, the video format that you are watching not only determines the quality in which you can view the material, but also in the way you may perceive what is happening on screen. Let’s take a quick look at popular video formats of recent years to compare their influence on our viewing pleasure.

The CD Video format was the first true foray into the idea of digitising video to preserve the quality of an image without the hassle of rewinding the tape and damaging the reel in some way. CD video discs came in a number of different forms and offered a few different resolutions and playback quirks that eventually led to the standardisation of the format.

From Early days to Happy days

CD Video featured encoding of analogue video combined with digital audio on an 800MB sized disc that allowed the playback of standard resolution video. The gold-disc format only lasted a few years though, with an improved all-digital Video CD format superseding it in 1993.

The advent of the DVD changed the scope of how the general public watched films and listened to music forever. There was a format that offered full digital video and audio in a number of different quality specifications with no degradation of image or audio quality. The disc video format had reached maturity.

DVD Libraries gave us the power

The DVD disc saw the introduction of affordable playback devices on the market, and when the PlayStation 2 Launched bundled with a built-in DVD player, the cost of a standard, no-frills DVD player tumbled into the tens of dollars range. The introduction of recordable DVDs such as DVD-r and DVD—RW allowed people to record television programs and home movies onto a format that would last the test of time.

Soon after the introduction of the DVD, Sony worked with a few counterparts to launch the Blu-Ray DVD. This format was a far more advanced format that allowed for much more information to be stored onto a disc. Whilst a standard DVD could hold up to 4.7GB of data (expanded to 8.5GB when dual-layered) a Blu-Ray disc can hold up to 25GB on a standard disc, which expands to 50GB using dual-layer.

High-definition storage on Blu-Ray DVDs

Blu-Ray DVDs are the perfect media format to store HD (high definition) video recordings on due to their large file size. Blu-Ray movies often have many hours of extra footage thrown onto the disc, as well as providing a series of DTS, 5.1 and 7.1 digital audio for that truly immersive experience. BD-ROMs also serves as a great medium for video games and computer storage.

The next big thing to come to video formats and storage systems are yet to be seen for 4K+ video and extended 4K 3D films and movies. Many companies are at work trying to find the perfect storage solution for these gigabyte-hungry video and audio formats, with storage mediums such as Holographic discs that can store up to 6TB of data and even Graphene Discs that may store upwards of ten times that amount.
