Video Lines issue

It's not that the camera isn't great, the sensor isn't all that big.
You can't expect amazing low light images with a sensor the size of a quarter. It just won't happen.

I'm not expecting amazing low light images. Just take a second to view the screen capture and you can see the banding. It looks like a grid. It is not low light noise -There is a difference. Even in the brighter location of the sky at dusk.
My PV2 does not have this issue when I do a side by side comparison.
I was simply inquiring if anyone else had noticed this issue in the PV2+.

The rub is that the Vision's sensor is nowhere near the size of a quarter. It's a 1/2.3" sensor which means it's 6.16mm wide and 4.62mm high.
The OP's screen capture does not look like any low light noise that I have ever seen. It looks like he has a defective unit.
take some more pics with different iso and white balance settings. also take a RAW image and process it on your computer.
I don't know if you have more than one picture with different settings but that is the first way you can start to eliminate defect vs. poor sensor performance in low light.
Also, it has been discussed on here multiple times, horizontal banding in video due to propeller shadowing. That could also be the culprit.
Another thing is the bright LEDs under the arms work on frequency, which may be interfering with the image.
Check all those things out.

Yes, I got the same problem - really annoying. The videos in low light situations are useless. It is a really strong grid which does not move. I checked a lot of other Youtube videos - some are really good without the grid, but some are as horrible as mine - like this one I found: https://www.youtube.com/watch?v=AGnP5zDpJmc
Compare it to this one: https://www.youtube.com/watch?v=7lXPFC46nt4 (not the plus version though) or this https://www.youtube.com/watch?v=U0hJG8ccI5M (filmed with the plus version)
I had my dealer contact DJI over this issue - I am looking forward to their reply. It has to be the sesor. If this cannot be fixed, the camera is totally useless for me.

It's interesting the 'good' low light one was a while ago and the bad ones are relatively recent. I wonder if they are using a different anti-alias filter on recent models - or could it even be firmware related.
I have seen some comment that video quality took a hit after a firmware update in the summer - can't say I noticed anything though.

I have a similar issue although mine is not a grid pattern but more random lines and snow. On mine it seems like an overlay though. Kinda in front of the image. Looks like crap. Low light/night only.
Having similar problems here. I don't have a lot of free time during daylight and took my Vision Plus out for the first time tonight. Here is a link to video but it looks pretty awful...I've seen some pretty nice looking one others have uploaded though so I'm hoping its some thing i can fix. Any tips would would be very appreciated.

oddly enough they look a bit better on youtube then they did on my hard drive.

thanks, your youtube videos show the same grid - if you change it to 1.080p resolution and fullsize view. I hope DJI has a satisfying solution for that. Otherwise the camera is unusable for low light conditions.
