I am creating a video on how to use a company app on a mobile device. I'm able to record the video on my phone and get it into Camtasia. where i am struggling is with the settings to get this to display correctly when played on the iphone. I am sure there is something i have to change to produce to a certain aspect ratio, but i am not sure what it is. When i produce using my regular settings that I use for any desktop based video, it appears very small on the iphone and doesn't fill the screen. any tips on what i should be doing to produce videos on apps to play on mobile devices? thanks so much....first time and i am a bit clueless.
