Making Your Own DVD? What You Need for DVD

By Sherri Loud


Today's technology has made the process of creating movies quite easy. In fact, you merely need to have a camcorder and video editing software. Digital equipment has made the process easier than ever. Once you have finished creating your movie, you need to move it to the recording software and make a permanent copy on disc. Necessary items will include a DVD drive, and of course, blank DVDs.

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-A DVD does not have any data on it when you first purchase. It is important that you purchase blank DVDs for recording movies instead of CDs. The two types of media appear very similar, so you will need to examine the label on the packages to ensure you get DVDs. You will also need to ensure that your blank DVDs are compatible with your DVD player, since several different DVD formats currently exist.

Software - If you have DVD software you will be able to format your movie and record it onto the DVD properly. This software often comes as the companion to a DVD player, or with a new computer. If you are buying a proprietary computers, such as an Apple, you will find that it has its very own set of DVD software. There are commercial third party applications however that will come with a typical computer.

DVD-R - DVD-R is a format that has been around since 1997. Having been developed by Pioneer, it is the most common DVD player format. Pioneer improved on their format in 2005 by releasing a dual layer version. DVD-R can only be recorded on a single time, and the single layer holds 4.71 GB. Dual Layer DVDs, in contrast, can support up to 8.5 GB.

DVD+R-The DVD+RW Alliance developed a competing DVD format known as DVD+R in 2002. The DVD+R format uses a variety of technologies that make it more reliable than DVD-R, such as Address in Pregroove. The error management system of DVD+R is also more robust. The capacities of the two formats are virtually identical.

Competition - The formats are not compatible, directly anyway, and as a result, the community and user base is split in half. DVD drive manufacturers have responded by creating hybrid drives that support both formats.

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.
