3D films and DVD’s

If you are lucky enough to own a 3D television then you may be shocked at having to pay quite a bit extra for 3D films. You cannot often get 3D films on subscription-based film packages such as Now TV and Netflix so will need to buy the DVD’s to get the 3D version. New, these DVDs range from about £15 upwards of £20, so possibly an extra £5 to £10 compared to the normal version. This can very quickly add up and you may find that not only did you have to pay a lot more for your 3D TV to start with but it carries on costing you for years to come. You will also need to purchase 3D glasses (not all 3D televisions come with them) and these can be £30 plus per pair.
That being said, some of the films offer an amazing experience and really do immerse you in the film. It can make special effects even more special and bring any film to life.
To get the full effect of a 3D film on DVD, be sure to use a high-quality blue ray player and make sure that the room is quite dark. Background light or reflections and really spoil the effect and render the 3D element useless.


What’s the difference between CD or DVD duplication and replication?

Although the two words essentially have the same meaning, in the optical disc industry, there is a big distinction in the terms, and how they refer to the manufacturing process of the final discs.

Duplication: Manufacture of discs using blank CD-R, DVD-R, Blu-ray-R (BD-R).
Replication: Manufacture of the discs from stamper and glass-master, pressed from polycarbonate granules.

For duplication, blank media is used, for example, such as mentioned above and data or audio files are copied onto the disc. The discs are then printed. In the CD replication or DVD replication process, a glass-master and stamper are made for the required content, which is like a master copy. From this stamper, the discs are ‘pressed’, similar to an injection moulding process, where the disc starts off in its raw form as polycarbonate granules.

Advantages: Duplication is cost-effective on 1-400 copies, or when a fast turnaround is required. Replication is cheaper to manufacture once the quantity is 500 or more, and the final discs are considered professionally manufactured discs.

There is no difference in the sound quality of audio CD, or any difference in the quality of the data copied on the discs between duplicated and replicated discs.
