How to set the MediaRecorder to get the best video quality effect?

Guys can someone tell me how should I set the parameters in the MediaRecorder in order to get the best video recording effect possible through coding without considering the physical limitation of the phone? Or is there any effect of the view small distortion caused by my coding of the MediaRecorder?

If some of you might be guessing of the unclear parameters I'm actually setting some of the parameters using preferences. What are the parameters I miss which might help to improve the video encoding process Ex: framerate
