DVD bitrate calculators compute the bitrate figures for rendering your video to a DVD-compliant MPEG video file. Bitrates are measured in kbps and determine the final quality of a DVD as well as determine the video duration that can fit into a DVD disc.

Standard DVD authoring software come with fixed bitrate selection, usually at 8000 kbps, 6000 kbps and 4000 kbps. At 8000 kbps, you can store about 1 hour of good quality DVD video, 6000 kbps about 1.5 hours of medium quality DVD video and 4000 kbps about just over 2 hours of poor quality video.  It is highly recommend to set bitrates above 5000 kbps to maintain quality.

For more sophisticated video editing software like Sony Vegas Pro and Corel VideoStudio, you are allowed to set the DVD bitrate.  This allows you to maximise the use of your DVD disc for the length of your video at the best quality.

Here is a recommended DVD bitrate calculator online:

When using the above DVD bitrate calculator, just type in your video length and the bitrate will automatically be calculated.   Remember to add another 5 minutes to your video length  for buffer and to reduce frustration of rendering your video again.

Enjoy!
