I just got this a few weeks ago and I did a short night video with it and I wanted to know if there is anything I am missing settings wise to get better quality? I am using an external lapel mic run to the bumper above the license plate. It is cheap little mic. Not sure what type of mic would be better to capture higher quality sound. Any suggestions? I am planning on using it for track day vids to look at how I am driving and also want good sound. I will use it when I take drives in the canyons along with friends in their cars as well. I will likely get another Hero 4 soon to get 2 angles in order to edit them together for more interesting vids.
