These are first screenshots of Camtasia Studio Recorder for Mac a prototype of which was demonstrated at the Apple WorldWide Developer Conference recently. Going forward, both the Mac and Windows version of Camtasia Studio will sport a similar interface.
The advanced audio settings like volume control and sound level meter are available only when the Audio setting is turned on. Smart approach.
I have a strong feeling that upcoming Camtasia Studio 6 release for Windows will have a black color scheme similar to the one they introduced with SnagIt 9. TechSmith has already introduced Camtasia Relay which includes a screen recorder for Mac as well.
Troy Stein, Camtasia Studio Product Manager, says – "We got two thumbs-up on the Camtasia Studio Recorder and Editor prototypes. We have some redesigning to do on the Producer module. Mac and Windows users will have the same experience."
