Video Edit Magic's capture tool lets you change video settings like Output Size and Frame Rate along with audio settings. To change these settings click on the Tools menu and select either Camera Settings, Video Settings, Audio Settings.
You can also use the Camera Settings, Video Settings and Audio Settings links given under Audio/Video Settings on the main Capture dialog.
The setting dialogs are driver specific and may vary between different operating systems and the configuration of your camera. However, you should at least have options to change Output Size (dimension), Frame Rate and Recording Format using the different settings dialogs mentioned above.
