Gary Evans 0 Posted May 26, 2013 Report Share Posted May 26, 2013 This is a new quad set up that I flew only once earlier without this problem. Note that the top edge of either the first frame or the first part of the originally longer clip shows at the bottom. The only thing I changed from the first flight was to add a LCD panel to the ground station which may have nothing to do with it. Any ideas on what may be happening?

Mr.RC-Cam 129 Posted May 27, 2013 Report Share Posted May 27, 2013 Note that the top edge of either the first frame or the first part of the originally longer clip shows at the bottom. Do ALL the display devices have the problem or is the DVR the only thing that is having this issue? The only thing I changed from the first flight was to add a LCD panel to the ground station which may have nothing to do with it. Never assume anything. Undo your last changes and see what happens.

Gary Evans 0 Posted May 27, 2013 Author Report Share Posted May 27, 2013 The DVR, Goggles and LCD screen all showed the same thing. It only occurred that one time and I am not seeing it on the bench. Quote Link to post Share on other sites
Mr.RC-Cam 129 Posted May 27, 2013 Report Share Posted May 27, 2013 It looks like a problem that can be caused by marginal vertical sync performance. Poor video syncs can remain undetected, but eventually may appear as video tearing and other problems. It is often provoked by the content of the video image or if other things occur that further compromise the marginal video signal. So your bench testing should include tests that attempt to duplicate the same lighting conditions; That is, very bright sky across the top horizon with a much darker ground view across the bottom. Plus try other combinations of scenic lighting to see if any cause the issue. Quote Link to post Share on other sites
Terry 5 Posted May 28, 2013 Report Share Posted May 28, 2013 How many times have you had this happen? My system did this once but since it has been fine, I put it down to a voltage spike at switch on. Terry Quote Link to post Share on other sites

Terry 5 Posted May 30, 2013 Report Share Posted May 30, 2013 Maybe the same as me and just a reboot to get it back on track Terry Quote Link to post Share on other sites
