Hi, I have windows 10 and camtasia version 8.6. I recorded a live goto webinar that i played in fullscreen mode. I didn't use custom settings, I just selected Fullscreen option. When I play back the *.trec file within the Camtasia editing window, the playback has a lot of black around the actual video, which is about 1/2 the size of my monitor screen. I tried adjusting the dimensions, increasing the percentage playback(it just loses quality and goes off the screen)...nothing works. I never had this problem before, but I need it to play fullscreen or I can't see the details. Please help.
