I have a recently purchased Mavic pro platinum. While taking 4K video of fireworks last night, I noticed that when I reviewed footage there was a circular vignette which inside the video footage. The vignette is a slight but noticeable shadow which remains in a central location of the footage. Outside this vignette is a noticeable slightly grayer area. I thought that this was residue from the sticky plastic lens protector when the drone was purchase and subsequently removed. But the lens appears clean. This image vignette is still noticeable when I downloaded the images to my laptop.
Any suggestions?
