Online Video data rate calculator.

Digital Heaven have released their Mac OS X video space widget as an online application. It allows you to work out how much space a given amount of video will take up on your hard disc.

It's aimed at Final Cut Pro users so the codecs are mainly ones found in a Final Cut installation (though the Apple Intermediate Codec is missing, possibly as it's a variable bit rate codec which makes final figures unreliable.) However some of the codecs, such as DVCpro, HDV, uncompressed in various sizes are cross platform.
