I really like the Royalty Free feature set. It's a bit on the expensive side- but it really makes a difference. (Plus it keeps the Youtube copyright pita off your case.)
Anyone using SmartSound for their vids?
How is the integration of your chosen editing prgms? The Quicktracks are really simple to use- but SonicFire Pro is amazing.
I am at the point where I am seriously tempted to make the leap to Adobe Premiere just for this integration alone.
From what I see, you just export your vid. to Sonic Fire, score the section you are working on and then back to the main for final edit and you are off and running.
