4K60 & best settings

bjhirsch · Jun 5, 2020

Hello

I am new to drone video & Mavic AIR 2 and have a small problem with my video settings or quality. But I guess it is rather user error than hardware

Tried to fly last weekend for the third time, as it was a bright & sunny day (afternoon) I out on the ND 16 (but forgot to but the shutter speed on manual). I looked to the histogram and did a minus -0,7 exposure compensation and locked that value.For best quality in slowing the video down in post I selected 4K 60 frames. I may need to add that it was a bit a windy day and I think I flew in normal, not tripod modus.

I flow over a canal with trees on both sides (10-15 meters away on each side) and when I now look to the video the leaves the leaves of threes look very artificial / strange even when I reduced the video speed to 50% = 30 frames per second. Same in 100% or even 200%.

I expected a better quality (the canal is nice & sharp) so is this due to

Not manual setting a correct shutter speed of 1/120 sec
Filming in 60 frames for quality & possibility to slow down, 30 frames would have been better
The wind moving the little leaves & the drone too much (but gimbal did a great job to keep drone footage stable)

Or the mix of all three ???? Really wondering, in a first impression I was more happy with the 2,7 K of my mini … therefore I am sure its is a user setting error.

Thanks for any help and TGIF

PS; here is the. short video uploaded : Premiere export source resolution:

Can you show the video ?

Many variables , codec H265 can be too much for computers , unless within the last couple of years and high spec . Try H264 in the settings. Also what are you viewing on ? If it’s not 4K you won’t get 4K. Try uploading to YouTube , try viewing on a 4K tv (presuming of course you don’t have a 4K monitor.......hence variables). Other options are mp4 and MOV, I found the latter better being on Apple.

I don't have the MA2 but the 60 fps footage taken by my M2P is bad compared with 30 fps. The reason is that the camera under-sample the image at 60 fps. Not sure about the reason but it may have to do with computing resource or heat dissipation

Ok so now I have seen quite a few videos with this type of fluctuation on the roof tops and some building, this may be a firmware fix needed.

I have not seen any of the Mavic 2 Zoom with the same fluctuation which is why it may be a firmware fix.

Interesting and great example .

DJI will not fix anything. They had multiple problems with the Mavic Pro. Had problems with the air. Imho it is related to sensor size (smartphone type 1/2“) and compression. Sensor introduces noise in the dark areas and compression with h265 seems to make things worse as it introduces a lot of macro blocking. 60 fps is killing it. Imagine feeding double the amount of data into tiny drone.

I am pixelpeeping since i want to replace my air with air 2. If there more video issues i have to go with pro 2 or wait for 3.

just my 50 cent as a filmmaking nerd
