Hello,
I have both zoom and pro 2. I m a journalist in Brazil and i do work for broadcast Tvs. I did some Mavic zoom tests first, recording videos in all common situations, and whatching all videos in 50" TV.
In low light situation i have noticed pronouced white noise dots in all dark areas. It is not dead pixels. All white dots are randoming, like a normal noise, but white. I ve never seem anything like that in any camera i ve owned. It is not a defective camera. I guess it is a software flaw, but im not software specialist. Night shots are unusable and i m very concerned about this.

Those white dots dont apear in small monitor and copressed youtube samples. They appear only when you watching original samples in big screams. I ve tested many cameras and Tv monitors. I didn t begin mavic 2 pro tests. I decided starting with zoom. I did set up sarpness from +3 to -3 as well as other settings. I d like to know if DJI could fix it in firmware update. It is a big concern for me.





Thank you

I will only suggest what others will ask:  Could you upload a sample video so that it can be looked at?   Also, these are videos from the drone (internal memory or sd-card) and not your phone or tablet?

You can upload to YouTube as "hidden" or "private". You don't have to make the video public and you will still be able to show it in here. Alternatively, you can upload to google drive and copy a link intended for sharing.

Thank you,

youtube quality is not what i need to show the problem. I guess you wont see it due to small size and compression artifacs. I will try google drive for original files.

Mavi 2 pro has that same issue. I found some complaints about white noise dots in Mavic 2 pro videos and photos. Id like to listening from DJI if they could work to fix it.
