I've only had my Mini 2 for about 3 days but I'm starting to see a bit of a pattern that concerns me. I'm getting some noise or grain in my 4k footage under at least a couple of situations but not always and I don't have this behavior on my Air 2. It occurs when I'm running in the birds-eye view and also when I move the gimbal up or down (possibly a bit too quick but nothing extreme).  I'd like to see if this is just due to the smaller sensor or ???  
I've linked to an example. The last 10 seconds really show off what I'm referring to. I see the same behavior on my computer (but I haven't loaded it up on my TV to check it). Any thoughts?

I've watched that through twice at full screen, and I'd be hard pushed to find fault with it?  Maybe it's my old eyes

Hello there InsaneDiego. Thank you for reaching out and I am sorry to read that you are having an issue with the video recorded on your DJI Mini 2. Let me please forward this concern to our Designated Department and once I receive a reply, I will send you a notification as well. Thank you for your understanding and support.

Looks good enough to me

I'm noticing what you are calling 'noise'.
It is most present in the 4K render.
It looks to me like compression artifacts as it only occurs in areas with lots of details.

This is a unedited file right?
Maybe youtube messes with it, (it does, but I'm not sure if that is causing it)
I don't own a MM2, so can't check myself, but can you change anything tot the video quality?

Yes, compression artifacts is probably accurate. It is an unedited file and it's not YouTube that's doing it, it's present on the computer as well. I have seen it show these artifacts in the birds-eye, moving the gimbal up, and also in the dark details of bushes or trees. I would think at 100mbps recording these wouldn't be present but they are.  I'll need to see if it's repeatable in some form to know how to handle it. Again, I've never seen a hint of that using the Air 2.

It's possible that it's the viewing device. I'm on my 15" HD notebook right now and in 4k mode it is hard to see the artifacts. I normally work on my 32" 4k monitor. Maybe in this case, size matters.

What size and resolution is your viewing device? I just checked it out on my 55" 4k TV and the dead grass sort of flickers.  On my HD 15" notebook in 4k mode and my iPad in HD mode, ya, it looks basically fine and I would never notice anything if I wasn't explicitly looking for it. Thanks.

Maybe too much of a good thing   I'm viewing on a 24 inch HD monitor.

There are several factors in play here, but you ruled out the most.
(youtube compression, editing software, bitrate) so there is not much left than the device we watch on or something inside of the MM2.

Due to the comments, I've gone back and looked at the originals on my 20" (22?) HD monitor. You do have to be pretty picky to see what I'm referring to. I also hopped around to the various clips I've shot and I had a hard time finding the problematic footage I had seen in the previous days. The fact that I'm viewing on a 32" 4k monitor in full screen with my face 20" from the screen certainly seems to be playing a part. To be fair though, the Air 2 doesn't have any of this. For now, I'll attribute it to the smaller sensor in some isolated situations and see if I can run some tests to narrow down the scenario(s). Thanks for the help. I just needed to understand if this was something that is showing up as common on the Mini 2 or not.

It's probably YT compression

That is exceptional quality for a $500 camera drone.  I am impressed actually.

Maybe it's just my monitor, but the picture is crystal clear at the beginning when the drone is static and goes blurrier when it starts moving. When I pause it, the picture is sharper again, so it looks to me like the shutter speed was too fast, which would be cured with an ND filter. My two cents.

Thanks, Chicken. I use ND filters on my Air 2. I'll have a look around and see what is available for the Mini 2.

You're welcome. That should fix it, IMO.

Yes, that is similar to what I see on a bigger screen. I'm not sure if there is much to do about it. I did a quick test in the bright sun today and lowered my shutter speed to 1/200. It was as low as I could go before everything was completely blown out. It did help a bit so the ND filter may be a solution.

I try to buy  nd16 filter made frewell ..

The mini has no settings for adjusting the sharpness and as such everything is really sharp. When you see fine detail such as the straw or lines in things like roof tiles you sometimes see some issues with the footage. It is also worth noting I can tell you aren't using an ND filter. ND filters are good for lowering the shutter speed and allows the footage to have a more natural movement blur. I recommend getting some ND filters if you want smoother movement footage.

Looks OK to me too.

If you can read this, your videos have the same problem as OP's. The shutter speed needs to be slowed down with a neutral density filter.

Tks prairie ..tomorrow try and play whit nd 16 ..

I am having the same issue and have footage where the problem is extremely obvious (see Youtube link below). You can see that it is actually a moire effect probably due to oversharpening. Please DJI allow us to adjust the sharpening and/or to disable it. I prefer to sharpen manually.

- The issue is in the original uncompressed material too and not due to Youtube.

- The issue occurs with any device (PC screen, phone, tablet, TV).

I have the same issue with my DJI Mini 2 footage. I thought this is the phone issue because when I'm using my iphone XR to record a video (without connected to RC or the drone) it also looks grainy and noisy. What phone you are using currently to record that footage?

I have this problem .. I try with the filter nd ... if I don't solve it .. this is a serious problem .. and this does not depend on the screen.

I'm using an SD card to record. A nice high-speed V30 card. The same one I use in my Air 2.

Same as mine. I hope they can fix this in the new firmware update.

I got a set of ND filters. It didn't make a bit of difference. I think sharpness plays a part when you are rotating the craft and you have very fine detail, almost moire conditions. The bigger problem is the raising and lowering of the gimbal. It's like it adds digital noise and I don't see that in the Air 2. The condition only occurs when you move the gimbal up or down too quickly. You get that grainy haze over the image (that again, is really only obvious when you are looking in 4k and up close). The solution is to be slower on the movement of the gimbal. It has no issues if you hit the speed right. To help to that end, I've gone into the Gimbal settings and adjusted it so you can't move it quite as fast. I think the Cine is set for 10 degrees and Normal is 20. I did notice that my Air 2 had Normal set to 15! So I may lower the Normal even more if I see that I can't control the speed.

It's definitely not a deal-breaker on this model. It is, after all, 1/2 the cost of the Air 2. Since there is a pretty easy workaround, and again, only someone nitpicky like me would notice under the right conditions, this is a small compromise probably due to the smaller sensor and electronics on the craft.

Hello there InsaneDiego, sorry to keep you waiting. I receive a response from our designated team. Please be advised that what we can do is to set ISO to Auto and select Anti-Flicker to the corresponding frequency (50 Hz or 60 Hz). In Shutter Priority mode or Manual mode, manually adjust the shutter. Select 1/100S, 1/50S, or 1/25S for a 50 Hz light source. Select 1/120S, 1/60S, or 1/30S for a 60 Hz light source. If a concern occurs in a brighter or lighter environment when using Auto mode, the shutter will make automatic adjustments based on environmental lighting. Thank you for understanding and support.

At no stage in the process are you seeing uncompressed material, it is always compressed to some degree or other.

hello, I still filmed in 4k 30 fps, I made all the attempts and even with a filter nd 16, I am not satisfied with my  sensor, I work at ISO 100 but I see a lot of noise and excessive graininess the videos do not suit me absolutely , I have tried the sensor values suggested above but without satisfactory results. the problems of my sensor as well as not being clear, from an annoying disturbance on the rapid change of scenes .. I did some tests with some nervous movements wanted and it is very annoying. I would like to understand if it is everyone's problem or just my sensor and someone else here among us  , this is sample raw

The response from the team makes absolutely no sense since 50 Hz and 60 Hz are the frequencies of artificial light. In sun light this does not apply at all. Anti flicker will slightly blur the resolution and do nothing else. The problem is also not ISO related since the issue occurs under perfect light conditions.
