So if I don't "publish" I lose my screencast? That seems pretty lame. Also, as much of a CC fan as I am, why do you force people to license their screencasts under CC?
Cool. Thanks. If you want to differentiate yourself over what quicktime already provides, I would add in some basic titling, pointer highlighting and region zooming.
As it's completely free we used CC to make sure no uploaded video causes us any issues - but with future updates and plans we will add more options
