When I reach 360' distortion of crop lines become apparent. This is a unedited version, just wanted to get input of other pilots that might have come across this problem.It was shot at 1080 30fps..
Thanks for your reply. Yep, an official inspection would come with the proper permissions.It wasnt me who made the flight. I assume permissions were granted. and the generator was stopped.
But its more about the camera used,
This effect is called "moire' it happens when light and dark lines or other patterns are too close together ; the sharpness of the lens or camera software preset plays big part in this . The most DSLR cameras are equipped with so called low pass filter ,which will unsharp the image just a bit before the image hits the sensor.When I reach 360' distortion of crop lines become apparent.

Your welcome.Thanks for your advice and explanation Paul, I will try that....
Moire' is little bit complex to explain , because the frequencies are involved in this as well.
My expertise is in still photography ,the videography not so much. If I remember correctly in Nikon series cameras the D800 was the first camera made with and without LOW PASS filter; the one without LP filter was ,or is popular by wedding photographers ,because it can deliver were sharp images ( only problem was with dreses with fine stripes ,but that could be managed by masking in editing).
I thing in videography it isn't such a big deal to see little bit of this effect her and there; in some documentaries on TV (like" Magnifica Italia" etc.) you can spot it there as well.
Try to unsharp in camera first (very little) and second test try to unsharp in editing and compare what will work better
