Yeah, tracking is delayed, it will take a bit of practice to get it right. The main problem with framing in these situations is the vertical hold. Osmo tries to keep the phone at the same level, but slopes go up and down so you end up shooting the snow or the sky. There is a button for adjusting the tracking position, but the problem there is that I usually go the wrong way first (up instead of down). :-) Yeah, I flipped the direction in the settings, but I still at 50/50 chance of getting it right. I guess I'll learn eventually.
Object following would be cool, but the problem is drawing a square around the subject - I usually have my gloves on.
