Hi,
I am new at drone flying and have recently purchased my Mavic. In general, I am very pleased with the machine and am having a huge amount of fun with it.

I have a small issue, which may be more to do with my inexperience as a newbie. I have a "line" which sometimes appears on my videos. This is an intermittent issue and I have tried cleaning the lens of the camera mounted to the gimbal and the outer screen with Zeiss lens wipes and a lint free cloth.

The line can appear in various lighting condtions and it seems to vibrate, as if it were a hair on the lens, which is why I am mistified as to why cleaning the lens has had no effect. I wonder is it a reflection of the rotors or another moving part? If so, has anyone any tips as to how to eliminate the issue?

Hopefully you can see the issues in a short movie in the link below.

Many thanks for looking.

Remove the gimbal cover!
