I was just given the upgrade to Final Cut Pro 3 as a gift. Right now I have version 1.25, and the person that gave it to me was told that as long as I had any version of FCP, it would work. I have an older computer and am running OS 9 but plan on getting a new one (OS X). I know FCP 3 will run on both 9 and X, but will this work for me as I am upgrading from 1.25, which only works in 9? I would think I would have to buy the whole app. Sorry for the long question but I don't want to open the box until I know I can keep it. TIA.
