I have attached a screenshot from a video that I took with my Phantom 3 Standard. This is after rendering it in DaVinci Resolve. There is obvious pixelization in the sky area. It was shot at 30 fps on auto and I used an ND 4 filter. This pixelization is not seen on the raw video from the SD card. The settings I used in Resolve are YouTube 1080p Format: MP4 Codec H.264. Any ideas on what I am doing wrong?
