What could cause video banding or strobing when playing back a video on my device.  I understand that the same video that's on the SD card would be higher quality but the video that gets saved to my tablet (Nvidia Shield K1) during recording has strobing when played back.

The feed you get on your tablet is only intended to be used to frame the shots and gauge exposure. It is also only 720p resolution, whereas the same clip on the SD card may be in 4K.

But onother issue is that the tablet has to find a way to scale the image to suit its own display, and once this is done, the image can be quite compromised. DJI never intended you to judge quality when looking at the playback on your tablet.

Geebax had pretty much hit the nail on the head.

I don't see the same issue when I use my Samsung Galaxy S6 phone so it could have to do with re-scaling the image to fit my Nvidia K1.  Would like to hear from other Nvidia Shield KI1 users if they have same problem.
