A few days ago TechSmith released a new Labs tool called AppShow which is intended to allow developers to record demos of their iOS apps to include in the App Store. Just about the same time, Amit at Digital Inspiration posted how to do the same thing using QuickTime player. I finally carved out a few minutes to see how this all worked.
AppShow provides quite a few options to guide the user in creating an intro and various scenes; I found them to be overkill for what I was trying to do, but someone really trying to make something polished for the App Store might find these options useful.
First a note that you must have the latest version of OSX installed, Yosemite. Second, you can edit recordings made via either method via Camtasia Studio, or probably any other video editing software, but other than adding a quick title slide, I didn't do any other editing or processing using CS. I also chose to use a game instead of a library-specific app because I wanted to see how well the recordings did with motion and audio. The recordings were done with an iPhone5 and a mid-2009 MacBook Pro.
And finally, it took me quite some time to figure out how to export from AppShow to Camtasia Studio; couldn't find anything in the documentation or the File menu item, so here's your hint:
Here are four videos I posted to YouTube so you can compare the quality.
tl;dr Quality of all is quite good, and for quick and dirty QuickTime Player is the way to go - throw the recording into Camtasia Studio if you need to polish it up after the fact.
