Techsmith isn’t saying much except that they have “completely rebuilt” Camtasia Studio 8 and that editing will be much faster and easier in CS 8.
I haven’t seen the new version but if the following videos were done inside Camtasia, it is quite possible that it will at least have video filters and improved video titling. A comment on a Facebook page suggests that Camtasia Studio 8 will have more audio layers as well (you are currently limited to 3).
