DJI confirms: in the AIR3S the Anti Aliasing sensor is not present

Lots of photographers would prefer not to have AA filters as the believe images are sharper and look more natural and thats why many cameras don’t use, them as far as I know there is none on the pocket 3 camera and that works fine for video without it.

My DSLR doesn't have an anti-aliasing filter and it seems to be fine. The conditions to generate moiré are quite specific. Maybe because aerial videography involves flying around things, it may be more likely to encounter situations where moiré is generated? I haven't seen it yet in my own footage.

Does it fly over the roofs? It's one thing to make videos on the ground, one thing to make videos on buildings, roofs, and surfaces. -

The mirroless Sony for example does not have it, but they have reduced  with a high pixel density and a dedicated software that provides some cases in the bionz processor.

It doesn’t fly over roofs but I can attach it to my avata and try. I haven’t noticed the problems you’re having there are other videos out there flying over roofs maybe those guys have the answer.

FROM another users but useful per DJI Support:

".I'm doing some post work on the red roof aliasing problem right now. That is the craziest moire I have ever seen. I mean,...it's not your typical moire aliasing that can be blurred or smoothed over. The color bands are so thick that it can't be removed. It's not even "high" frequency aliasing that an OLPF (optical low pass filter) might catch. It's like "low frequency" aliasing! I don't know how it's getting there in the image pipeline...but to be honest,....I don't think an OLPF on top of the sensor can even catch that!  I suspect that this a nasty quad Bayer HDR binning artifact. In other words,...it's NOT frequency aliasing at all...it's HDR pixel image "blending" artifacts cause pattern "brightness" collisions on certain patterns."

At this point try Sharpness -2....is reducing a little, but comes at package also with loss of details...Details that already is affected by low bitrate that was implemented, killing all small details encoded by H265

Hi, there
Thanks for sharing your concern.
Compressing the bitrate is only under the premise of ensuring the picture quality
Saving storage space compressed bitrate does not bring moire or attenuate the moire problem.
So, please feel free to use it. Have a good day!

How do you compress bitrate to ensure the quality?
Please explain, as far as I know increase in CRF/decrease of P sample and decrease of bitrate in accordance means to kill details.
If was not like this, probably all videographers would import the so called "special algorithm" of DJI in their works, leaving the ProRes and DivxHQ... )))

So Wanda, please inform before affirming that lower bitrate = more quality...
Thank you

please can you add an option where you can choose to increase the bitrate like on osmo.
Thanks

Hi, there.
Thanks for sharing your concern.
Our engineering team has done relevant comparison tests to ensure that the current bit rate does not affect the picture quality. You can also compare it with other 150Mpbs drones.
If you still have doubts about it, you can provide the original footage and we will analyze it.
Thanks for your understanding.

I have to agree with this , the air3s is very close to that of the M3P certainly there is a slight difference but this is almost certainly because of the larger sensor and as far as details are concerned it matches up very well to the pocket 3 .

The same TEAM that developed the algorithm for Osmo 5 Pro?
The same team that proved that high BITRATE provides more details than standard bitrate WANDA?????

As she said the bitrate on the air3s compares to any drone with 150mbps and this is clearly shown in the video produced by many users on here, in fact you are probably only 1 of 2 on this forum that cannot get good video out of this drone. And speaking of the bitrate on the A5 most people are now using the lower rate because the found no change in the increase from 75 to 100mbps but you don’t own an A5 so how would you know.

Here we go again... Another thread going down the pooper...

You are that sucker that posted a photoshopped photo as DNG saying that you have 108 mpx at your Air3S, trying to lie all community here???
Yes ..you are, indeed.

Again more rubbish from a clown who hasn’t a clue what a lossless file is keeps saying stupid things about the Air3s and now asks for a moderator to explain. She does but he doesn’t accept . He once said the pocket 3 would be recalled , it just turned out to be djis second highest selling product of all time , hard to believe anything this guy says seems he’s making everything up

Can you post again your 108mpx DNG from your Air 3S?

Looks like you were put back in your box once again.

Still do not know the difference between DNG and Photoshop?
Or just try to lie again? I have told you, we all have seen your character and lies

I've had the Air 3S for about two weeks. I see two main problems. I think the bitrate would be good to have higher. The main thing is that when there is a lot of detail in the image and the drone moves quickly, the image is not so detailed and colored areas and artifacts are created. Sometimes hardly at all, sometimes more. The second, for me, major problem is moire. When the building has some structure (for example, a castle made of stones), stripes immediately run along the walls. There is also a lot of minor aberration in photos at 50Mpx, but it can be removed thanks to AI in Photoshop. 12Mpx is fine.

You're not the only one. It's a well-known problem.
But there is a bit of hostility towards those who point it out.

I also compared photos of Air3S vs Air2S. I have both. It can be said that Air2S is better compared to 12 Mpx of Air3S. For objects at a long distance, post-processing does not interfere as much. The 50 Mpx photo is more detailed than the 20 Mpx Air2S, but there are really a lot of magenta and green color elements. Photos from Air2S have a slightly different tone. 50Mpx photos with detail win, but color is worse than Air2S due to high aberration.

Agree.
This is the limitation of QB binned pixels... unfortunately this is the future that we have now, QB sensors and limited RGb.

Hi, there.
Since the drone is different with handheld device.
It's better to provide the original footage if you are doubt about it.
Thanks for your undertstanding.

Dear Wanda,

The footage of 60fps 4k is visually affected by low bitrate, you have a lot of users and Youtubers that provided you this issue.
Send me the firmware update for 130mbps at 4k 60fps and I will be happy to show you with two videos what is the difference, studio made, without intervention on them.
Now do you want me to compare your standard low bitrate with what?...Is noticeable in terrain grass and tree leaf the loss in details at 4k 60fps in HLG and DLOGM.

Cheers.

Hi, there
Thanks for your feedback.
However we have not yet received any information related to the firmware update for 130mbps at 4K 60fps.
Please stay tuned to DJI's official website, as we will update the latest news on the official website as soon as we receive it.
Thank you for your understanding and interest in DJI.

Can you tell us of any dji drone you know that has an anti aliasing filter ? I have been flying them since phantom 2/3 and have never come across one.

Hallmark007 Posted at 11-5 05:32

You are correct about this.
Most of the DJI drones don’t have HW anti aliasing filter.

So the question is: why we have never seen so many cases in other drones (certainly not so evident)?

Some Air3s are defective?
Is it a SW issue?

I can only see the effects, root cause shall be explained by DJI…

Avoletta1977 Posted at 11-5 09:33

It still can be seen in all 3 mavic 3 drones and many posed the same questions.If you have a defective drone it should be returned , I imagine software may be used to try remove the moire
