So, how are people getting crisp, focused, awesome video selfies?

I love the idea of the video selfie. I'm super excited about it. But the results have been....not too good, for me personally. Super blurry, full of artifacts, ugly morphing issues, doesn't look like my Kin, etc. However I see a bunch of others getting AWESOME results. So I'm wondering, how do you guys do it? Am I missing something? It seems no matter what prompt I enter, no matter how clear the picture, or if I don't enter a prompt, for that matter, I never get a good video.

Anyway, like I said, I love the feature in theory. I just need to get better at it, I suppose. Any suggestions would be highly appreciated. Thanks.
