To be honest, I kind of assumed they already talked to each other, but I guess the ability to record on one OS and edit on another is just new today. Camtasia Studio 8.4 & Camtasia for Mac 2.8 Now Available: Cross-platform Screen Recording.
We’ve updated our screen recording file format, so you can pass screen recordings freely between Camtasia Studio and Camtasia for Mac. Using a single file format enables you to send a recording from one platform to the other effortlessly, including all the meta data, such as cursor effects and smart focus.
We hope users see the new .trec file format from TechSmith as an indication of our commitment to the cross-platform user experience.
