Making Your Own DVD

By Philip Craig


The technology of today makes it very simple for amateur filmmakers to create their own movies using a combination of camcorders and video editing software. When you have finished making your movies however, you will need to record them. Today you will need blank DVDs along with a DVD drive. You will also need to know the formats, disc capacity, and various recording speeds.

DVD Drive-A DVD drive is the device that records your movies to DVDs. Most modern computers and laptops already have a DVD drive built into them. You can purchase an internal DVD drive separately and install it into an available drive bay. External DVD drives are also available which typically connect to your computer through the USB port.

Blank DVDs - When you buy a blank DVD, as the name implies, it does not have any data. As you go to the store, you will need to make sure that you are purchasing DVDs rather than CDs. DVDs have more capacity, and they play in conventional playback devices. Make sure you are choosing DVDs that are actually compatible with your device as there are several different formats today.

Software - If you happen to have DVD software, it will be easier to format and record your movie onto the DVD. Oftentimes this software comes with a DVD drive, or with a new computer. The software brand you get will typically depend upon the type of computer you are buying.

DVD-R-Pioneer developed the DVD-R format in 1997, which most DVD players currently support. It originally used a single-layer format, although Pioneer released a dual-layer version in 2005. DVD-R can only be recorded on once, whereas DVD-RW can be rewritten over 1,000 times. The capacity of the single-layer version is 4.71 GB and the capacity of the dual-layer version is 8.5 DB.

DVD+R - The DVD+RW Alliance created a format called DVD+R in 2002, and it uses technology that makes it more reliable than DVD-R. It boasts an error management system that combats many potential issues, but the capacities of the two formats are identical.

Competition - These formats are not compatible, directly, and this has created a severe competition. DVD drive manufacturers have attempted to create hybrid drives that will support both, but such a conflict has not been seen since the days of the Betamax and VHS.

Speed-The basic recording speed of a DVD is 1.32 MB/s, which is known as 1X. This speed will require approximately one hour to fill a single-layer DVD. The maximum recording speed is 24X, which will fill a DVD in about 4 minutes. Slow recording speeds typically use constant linear velocity as the writing strategy, whereas speeds above 8X generally use constant angular velocity.
