While the Free version may not let you export the image sequence you should still be able to make a digital cut and then just import it back into your computer I'll have to look that one up. I do know that anything done in FreeDV can not be imported into a pro setup.
I work on Avid Pro setups and DS/Nitris setups. I also do some FCP work. TBH, avid runs circles around FCP. So bascially if you do alot of this sort of work, you should listen to shakran's advice and go with the free version of Avid. The interface is extremely easy to use. Just make sure you pay attention to your tracks
