There seems to be a grid of black vertical stripes overlaying in overexposed area.
Is it some zebra indicator that I can remove before my output is captured?

Try adjusting the white balance.  It did the trick for me.  Also I don't think it shows up in the final video.  Putting the nd filter on helps too

Will check white balance. It does show up in the final video. Any clip showing the Sun is broken and I have to post-mask a tracked circle of brightness over it.

There is an option in the app to select or deselect this overexposure warning.  

It shouldn't be recorded if it's a marker. It is also activated by default.

You are correct. You can turn it on or off.

I think it is for the rule of thirds. Could be wrong as I have not used mine yet but, I did read see info that it was there and that you centurion it on or off. It would be nice if it is also used for over exposure. ON my high end Nikons just the area(s) that are overexposed get the blinks. Same thing as the Video Zebras.

Only way to fix is to underexpose and fix the brightness in post. Grid lines and over exposure warning are turned off. Even if I was able to turn this off, why would the 'monitor marker' be recorded?

It's a feature commonly known as "Zebra Stripes." It's to help the videographer identify overexposed areas. It does not show up on the actual recording. It is merely a tool that overlays on your screen while filming.

The only zebra stripes overlaying as a marker are in a 45° direction, overlays the vertical stripes and are not recorded. The overexposed areas are recorded with these 0/180° vertical stripes on my videos, when I should see white dots?

Hm. Don't know how it appeared.

hello , the exposure camera that inspire 1 is auto or no ?
I need that camera for auto exposure, you help ?
tank you,

I am having more important issue with camera. Last firmware update process made it unusable. Endless testing from one departement to another. I hope I would be able to replace the defective camera and/or craft free of charge or get RMA.

I have a similiar issue.
My first flight today and discovered some vertical lines in my final video. Also it comes and goes during the video... this was not what I expected... (Its not overexposure, as this was shot in the evening and it was overcast).

I have looked in the DJI pilot app and I can`t find this option.

The over-exposure warning is in General Settings.  General Settings is accessed from the four-dot icon in the top right corner of the App screen (if you already have a settings menu open, you should also have a column of shortcut icons down the left edge of your current menu window - the four-dot General Settings icon is the bottom one).  See image below.  Note that once in General Settings you need to scroll down to find this cluster.

Above information is correct for iOS devices.  I don't have Android though it should be the same.

I haven't encountered the artifact you describe (only the normal overexposure zebra stripes I've described in a previous post).  I wonder if by trying to actually shoot an image of the sun you are running into a hardware limitation.

When I was a child one of the things I learned was that by focusing the sun onto a dry leaf using a magnifying glass, I could make the leaf catch fire after just a few seconds.  Also, back in the days of tube-based cameras, the quickest shot of the sun (even if the camera was off and unplugged) would permanently damage the imaging device.  Since then I have scrupulously avoided a direct shot of the sun.  Even though today's solid-state imaging devices don't get instantly destroyed the way vidicon tubes used to, if the sun's rays through a lens can actually cause a FIRE I can't imagine they're good for any imaging device.  And I wonder if in this case the level of brightness you're trying to capture is simply overwhelming the electronics.

Nice, thanks. I see the app is certainly different from Android. You have a lot more general settings.
