Jitsi can support 1080p at 30fps, I'm not sure if it goes higher. However you may need to host your own as meet.jit.si has some quality restrictions (although it is pretty good looking for general use). Also note that most laptops only come with a shitty 720p webcam so unless you have a nice camera you won't see much improvement.
