What is the difference between DVD and Blu-ray?

WEDNESDAY, SEPTEMBER 28: Many people come into the store asking about the difference between DVD and Blu-ray, and whether it is worth switching to Blu-ray.

We briefly explain the most important difference — storage capacity — and leave it to the customer to decide if they want to make the switch.

A standard single-layer DVD holds about 4.7GB of data.

That is the equivalent of a two-hour movie and a double-layer DVD holds twice that amount.

A single-layer Blu-ray holds about 25GB of data and a double-layer holds 50GB.

Remember, almost all new movies are being filmed in high-definition (HD) digital video and no longer use chemical celluloid, which means that the level of detail being captured has increased, enhancing the viewers’ experience.

So to optimally watch some of the new high-definition (HD) movies, a Blu-ray player along with an HD TV will deliver a better experience, especially if a movie has a lot of special effects and computer animation.

The difference between DVD and Blu-ray is much less when viewing dramas, comedies or anything that relies on human actors and plots.
