This is a simple and easy to use tool from VideoHelp that will make calculating your video bit rates a doddle.

The bit rate is the average number of bits that one second of video or audio data will consume. You will usually find that better video or audio quality is obtained from files with a higher bit rate which will be bigger in size, while files with lower bit rates tend to have a worse video or audio quality.

If you are looking to take your video footage and edit it onto a DVD or CD you will need to calculate the bit rate to ensure that the best quality is achieved.

This program makes the calculation simple. Start it up and it takes you to the calculator, enter in the relevant details (video length, audio bit rate, DVD format) and the video bit rate is automatically calculated for you.

An advanced mode gives the option to include further details such as custom size and custom audio.
