Hello and welcome to Apple Support Communities, Chief195.
We understand that when you use your camera to record video the screen vibrates, so we'd like to help. Since noticing this behavior have you had a chance to Restart your iPhone. Sometimes giving your device a fresh start can resolve unexpected behavior. Also if you have a case on your iPhone, remove it along with any accessories that are attached to see if that helps. If the issue persists, reply to this message and let us know if this happens with other apps that have access to the camera, and if you notice this with the front and back camera or just one of them.
We look forward to hearing back from you.
Take care.
