I have brand new very powerful iMac (40G memory, 2 TB Fusion drive). I downloaded and installed Captivate today and tried a 2-3 second test video. It is just hung there saying finalizing video. Did another test with proper video demo project but with same thing. I like the features of the app but doesn't seem to work.
I tried restarting my computer and re-recording a clip of about 3 minutes. It got recorded successfully and the video finalization process was finished in few seconds. I guess restarting was the thing. Just letting you all know in case if it hits you.
