Camera settings should be in the preferences.
If I make a scene for a film, and I use 25 fps, and 1280x720 (720p) resolution, then it is a little annoying to be forced to set the fps and resolution for every new scene, since it resets to 12 fps and 800x600 in MainWindow2::newDocument().
I would like the new scene to be 25 fps and 1280x720 as well.
For this reason I would like to have fps and resolution in the preferences.
If you/we put it in Preferences, then there should be two radioButtons, so you could choose either a custom size (like now), or a predefined size like 640x480, 800x600, 1280x720, 1920x1080 etc.
