Editing tools for the timeline could be improved. There are several common tasks which aren't as easy as they should be. For example, it would be very useful to be able to select from the position of the playhead to the end (or start) of a clip with a couple of hotkeys and to use the Delete key to remove the selection. As it is, you have to select the start position, drag to the end of the clip and click the Cut button.
It would also be useful to be able to position the playhead, play a section of video and after, move back to the start position with a single keystroke. It's often necessary to play a section more than once to decide where to make a cut.
You can record a narration for a video at the same time as recording the video, or add it later in the Camtasia editor. For this you can unlink the video and audio tracks, if needed. You can also add captions and symbols - such as arrows - to a video, to highlight particular details.
When the video is ready, it can be rendered as MPEG 4, or specifically for common destinations like HD, iPhone, iPod and YouTube. Techsmith has removed the earlier Flash format from the options list, though, leaving only the latest MP4/SWF. This is perhaps a bit premature, as there are plenty of applications still requiring earlier Flash input.
For example, when producing the recent Microsoft Office screen videos, all of which were produced with Camtasia Studio 6, we had to use a third-party program to convert the MPEG 4 output to Flash, so they could be streamed. This won't be a problem long-term, but currently it's annoying not to have legacy Flash support.
Despite some lack of sophistication in its editing tools, Camtasia Studio 6 is a very competent screen video recorder. SmartFocus, used sparingly, improves the quality of finished videos and the familiar video editing paradigm should make it easy for anybody to pick up the basics quickly and become productive.
