I recently received my Mavic Pro, could not wait for the Mavic 2 because of my trip to the US.
So I did a bit of testing and I noticed allot of noise in the video even at iso 100. These are my setting: 4k, 30fps, 1/80, iso 100, sharpness +1, d-cinelike and standard
When I use 0 or -1 sharpness the image becomes blurry and not usable in my opinion. So is this normal with these kind of settings in sunny daylight.??
It's visible acros the full frame of the video and even more noticeable in de shadows, like trees.
Hi there. thank you for reaching out and sorry for some inconvenience for what you experiencing. Regarding with that may I ask if are you using a Recommended SD card? or at least class 10 or higher?
This is unfortunately a well known problem, I have switched back and forward between D-log and D-cinelike with different sharpness settings and DJI have gotten the request/proposal several times that they should have a separate "button" for noice reduction in the GO app which they obviously can't or will not solve.
It's like you describe that the "shadow" parts like trees and stuff loose a lot of detail.
This is an example of how it can look with D-cinelike and the settings +1 -1 -1
ND filter is on ND16 Polar pro, Iso 100, manual mode, Shutter around 60, 4K 30 FPS

Hi Flybee,
Nice footage! The noise on your video is less noticeable than mine. But I did no post-editing on my video. It was just a test of the camera.
It's strange because Dji support is telling me this is not normal and I should return the Mavic pro. However on the web I read allot of topics about visible noise. So I am not sure what is acceptable?
What you have is the so called temporal noise issue plus a bit od spacial noise. After looking into this like many quite a lot - the issue us that at most settings the firmware of the capture chip is automatically reducing the bit stream bandwidth by doing this area buffering of low contrast parts of the frame - these are updated every 8th frame - for you see the low surface detail on the water seeming to freeze and then update on the 8th frame. The spatial noise in the grass is due to high frequency sampling error which relates to the 60 megabit data sample rate. For me the solution is to on shoot at UHD resolution as the is near 4K but reduces the amount of data per-frame by a significant percentage - I also use the '180' rule and shoot 25fps shutter 1/50 (native Pal TV) standard. This helps remove the temporal aliasing. The high frequency spatial noise can only be removed or alleviated as a post process in the editing software - by using the Neat Video de-noise plugin. It's a slow but thorough process, and only worth doing on short amounts of footage. So usually the last part of an edit.
This is a common problem and I had it when I first started flying. Went through a bunch of suggested settings until I found ones that worked. Flybee's settings are pretty close to what I ended up with in the end so you might want to start there.

So this is normal behaviour? It's odd support is telling me to return the Mavic.

Hi.
Thanks, I did no post either (from a noice or sharpness point).
I have seen different results from different versions of Firmware, i'm now on .400 i.e. latest.
What is acceptable must be a thing that you have to decide upon your self.
I wish we had less noice but I'm used to it now somehow. I have learned how to minimize it at least.
If DJI say send in and you have guarantee I would say that it might be worth it.
I have one of the early MP's and got it replaced with an other problem ie. corners did not have "any" sharpness i.e. unusable.
Yup DJI support front end doesn't know the technical intricacies of the capture chip and it's various firmware settings. They are there to pick up on obvious faults across all the drone's functions. The settings you have (UHD at 30fps) should be fine just set the shutter to 1/60 per second and if possible lock the iso to 100. I find I'm using an ND 32 filter all the time when its sunny - just to keep the settings at these values.
Unfortunately that's the last you'll hear from Mod's ... they seem quick to focus on the SD card and not the known limitations of the dynamics of the chip and associated firmware that supports it. Try some of the settings suggested by Flybee ( post #4 ) and fly into some of those higher contrast situations. I've notices similar outcomes when there are changing reflective surfaces (lake ripples) next to shadowed areas. Tough for an image chip to handle, even with still cameras.
This evening I tried the 4k 3840x2160, 25fps and compared it to 2.7K 2720 x1530 25fps. The 2.7 looks much cleaner and almost no flicker and less noise, seems like it's compression noise at the higher resolutions. If you rotate the gimball it's very noticeable. So I think I will go with 2.7K

very annoying issue, present on 4K resolutions. On Phantom 4 partial remedy was turning off 3D noise reduction in DJI go app, but on Mavic there is no such setting.
Issue very visible if you tilt gimbal up and down quickly. Not so strong when you pan right /left
When I watch some older Mavic Pro videos (2016) on youtube in 4K, issue is not so visible or present at all, may be it was introduced as an "improvement" in some camera firmware update. Or intentionally ?
To avoid that issue now, you have to shoot at 2.7K of FHD, issue gone.
DJI, please plug 3D noise switch for Mavic Pro 1 into DJI Go APP
I am experiencing almost a type of interlacing look / noise on any lines in my footage. I've done everything I can think of to do. All different resolutions reflect it. I've reset to factory defaults. I've rolled back firmware. All to no avail. Anyone have any solutions? I'm desperate to have to resolved as I have some jobs to work. Strange thing is that if I go into camera/photo mode it's crystal clear. I hope someone has a solution for me.
