Shot this this morning, I really notice a lot of aliasing in the horizontal since I updated to 0300. Is there a setting to get rid of this? Shot in manual mode 3840/2160 24 FPS. Frame rate to slow? Also have some stuttering when videoing during rolling left or right. Doesn't show up as much in UT default 720p or 1080p, if you select 2160 resolution in UT settings it is really noticable.

I watched that in 4K on a proper 4K capable monitor and did not notice any aliasing, in fact it looked very good indeed. The FW upgrade will not be the culprit, it is most likely the monitor you are watching it on.

Thanks, I'm watching on a 4K 32" monitor as well, i7700 processor, just noticed the horizontal lines (wood walls along the boat slips) "moiré" as the drone moves during roll left/right when viewing in 2160p. If I select a lower resolution in the UT settings or media player it is reduced as the resolution is reduced? Looks the same straight from the SD card as well.

OK, well it looked fine here. In any event, there is nothing you can do other than choose another display. You can dial down the sharpness in the camera settings of the aircraft, but that only ends up making the picture look soft.

OK thank you, just read up a little on it, I'm going to shoot in 30 FPS instead of 24 next time, after reading the moiré is caused by the camera sensor, there are a few tricks to try to eliminate it, Thanks for the input!

Moire is part of shooting video, you cannot eliminate it, all you can do is reduce its effects by lowqering the sharpness. Remember, I was able to view it without problems.

I should point out, your clip was actually very good in terms of exposure and colour, and it was an interesting subject.

Thank you, been practicing with the manual settings, I'll betcha I bumped the sharpness up to high fiddling around too much!
