I made the first shots in 4K with the Inspire1. There are big compression artefacts in the image. blocks of squares are moving across the dark parts and detail parts of the image (trees for example) It is not usable! I compared with GoPro3 shot with flamewheel550 - there is a much better image without any digital artefacts. what can I do?may be the card is too slow can that be? is there any codec setting possible on the camera to improve the image? the 4K is useless if its compressed so much that the image does not work.
