Good for everyone ... when I fly indoor, a fine horizontal black line is produced in the videos, and to a lesser degree in the photos. I have tried in different configurations and it repeats.- Flying outside  haven`t problems ... the drone never fell.-
who has this problem? or some method of solution ..
Thank you very much
I'll try to paste a capture from a video

Does the line appear when viewed by another device?

Only indoors? That's weird. Maybe there's some radio interference inside that presents as a visual artifact?

I would have guessed a bad camera sensor or something but if it only happens inside then I would guess some kind of interference.   Can you try indoors at another house?

I would agree with Dirty Bird as it looks like a bad sensor.
