The transmitted video is 720p by the way, not 480p. Highly compressed though. You can change that setting under HD app settings along with transmission channel. Default is auto to attempt getting clearest channel and best compression so you get enough video for FPV and photography setup.
Remember, this isn't a DSLR. You have a long distance radio between the camera and what is essentially a viewfinder.
