Attention: RC-CAM.com will be closing down August 2021.

The RC-Cam.com forum was the very first online community dedicated to the advancement of wireless video cameras on radio controlled (R/C) models. This is now called "FPV" (First Person View). We are proud of the contributions that our members have made to the FPV hobby.

We've seen significant changes over the last twenty years. Initially there were a lot of eager R/C hobbyist that built their own video systems. Allowing these creative individuals to share their work was the purpose of this site. Now the FPV market is flooded with low cost systems; Sadly DiY FPV video projects are now rarely discussed.

RC-CAM.com (main site and forum) will be closing down August 2021. This is being announced now (March 2021) so that everyone has time to download any information that is important to them. After the site is shutdown the information will no longer be available here.

We appreciate every member's involvement with advancing the FPV hobby. It is indeed sad to say goodbye to all our online friends. Be safe and stay healthy.

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?

Do ALL the display devices have the problem or is the DVR the only thing that is having this issue?

Never assume anything. Undo your last changes and see what happens.

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.
