One question we see a lot on the forums, in fact there was another one today, is "How much storage will I need for X amount of video?" Our friends at Digital Heaven have created a wonderful free widget for those of you on Mac OS 10 computer systems for this very thing.
Call VideoSpace, all you do is enter the video format and the amount of footage you have (in hours and minutes) and voilá! You get exactly how much storage it will take to hold that amount of footage. And keep in mind, this is just the raw camera footage, you also need to factor in space for graphics, renders and audio files. It's a great little tool and I highly recommend it!
