Video performers

I want to get into making stuff today I made a video of me stuffing my face with 4 Big Macs and mchickens and 2 shakes but I am not happy with audio quality and my camera looks like ass, but I looked fat AF and got really stuffed I’m just wondering for the future how to do things better

Well depends of the micro and lightning and the angle of the camera but in the future if you can buy a better camera that would be level up of quality
