It is a hard video to judge in my mind because it's so focused on the player's airplane in black space that you don't get much impression from the scrolling background and how it's moving when the airplane jiggles. .

No.07869 Haze Senior Tester Nov 4, 2011, 00:34	I can't even see any 'trembling' of the airplane even if i discount the possibility of an unsteady camera. I can't see anything you're trying to describe.
No.07870 Kold666 Developer Nov 5, 2011, 07:52	Don't you see from the video that the airplane before crashing moves back and forward from about 1-2 pixels when shooting? Ok, the video is not really crystal clear because of the 30hz recording, but it is near impossible to make the camera tremble only on one axis, so that shaking is actually the airplane. Btw feel free to delete this post because I have no other means to show you this

Could you make another one, a bit longer, and with the camera still (don't hold it in your hands, put it on a stack of books or something). Also, don't zoom in that much: with just the plane and black background in view, it's not visible what part moves.
No.07872 Tafoid Administrator Nov 9, 2011, 00:35	I'll acknowledge this pending some further video. No one can seem to divine just what is happening from that posted video.
