Hello and thanks in advance.
I clarify that I am new to the world of drones and photography, I am trying to learn.
I find it hard to explain the problem I have, I notice a judder especially in very white and shiny things, it is very noticeable in areas with many white ceilings, in short it is as if it were not very fluid. I use the mini 3 pro with ND filters (32 and 64 during the day) and I try to respect the 180 rule, I film in 4k 30 fps, I leave the ISO at 100 and the shutter speed at 1/60 or 1/80 (trying to keep the exposure below 1) I leave the following video as an example:
https://drive.google.com/file/d/1vELepS3T2QsuaEWV7TCNHvUb4EGNKxwt/view?usp=sharing
The error is noticeable from approximately second 30 (0:30) I would appreciate it if you could guide me as to where the problem is, greetings.

Hi there,
thank you for reaching out.

Before we provide further assistance, could you please confirm whether the issue occurred in this video only? If you have a different video sample, please share it with us.

Looking forward to your response.

Hi there,
thank you for reaching out.

Hello, first of all, thank you for your response.
The problem has occurred to me in other scenarios, I get the feeling that this "flickering" occurs in very shiny areas such as the roofs of houses or white buildings or metal roofs, it also happens with the horizon with the sky, in this video starting at 00:12 second if you look at the horizon you can see the problem:
https://drive.google.com/file/d/1HT8B9NPG8E00_8zU9aM-dJlWI7vOlMVy/view?usp=sharing


In this other video, this problem is also noticeable on the horizon starting at 00:55, and it becomes even more noticeable starting at 01:10:
https://drive.google.com/file/d/1tyRasdx2_ynuRnDzPHvvIi0VCAmIKjEu/view?usp=sharing


In this other video it is also noticeable on the roofs of the houses when I turn the drone:

I don't know if it is an overexposure problem or some configuration that I am making wrong, in all these cases I am using ND 32 and 64 filters at 40k30 ISO 100, shooter speed between 1/60 and maximum 1/100

Thank you

Hello, and thank you for your reply. We understand the challenges you're facing as you learn about drones and photography. To address the judder issue you're experiencing, especially in white and shiny areas, we suggest the following steps:

1. Since you're in Uruguay, which operates at a 50Hz frequency, try setting your frame rate to a multiple of this frequency. Film again to see if the flicker goes away. If you're unable to find suitable frame rate options, please check the NTSC/PAL settings on your camera and try using PAL, as it is applicable in 50Hz regions.
2. If the flicker persists, adjust the denominator of your shutter speed to be a multiple of the frame rate.
3. Should the flicker continue, we recommend changing your filming environment or using a more stable lighting device. Alternatively, you can use a third-party anti-flicker plug-in during post-production to help resolve the issue.

We hope these suggestions help improve your filming experience. If you have any further questions, please feel free to reach out.

Just use 60 fps recording and throw away the filters ) Everything will be fine.

Hello, thank you very much for your response, answering your options:
1. I was completely unaware of this, what you suggest is that instead of filming at 30 fps I do it at 25 fps with a 1/50 shutter?
2. YES, I always try to set the shutter to double, in these videos I may use 1/80 when it should have been 1/60 (otherwise the image would be overexposed)
3. I didn't know there were anti-flicker plugins, I use Final Cut Pro for editing, maybe there is something to solve this effect

Thank you very much for giving me your time

Hello, thanks for your response. Yes, filming at 60 fps may solve the problem a little, but in the mini 3 pro the best image quality is at 30 fps or less, and it is also more cinematic at low fps speeds.

Greetings.

In general, it's best to keep a high framerate (50fps in PAL area) and move SLOWLY and don't do straight pans (if you introduce some 'other' motion, like a bit sideways and forward while panning, it helps).
If that all does not help, try ND filters, but I don't really need them.

And don't make the mistake as to believing slow framerates are cinematic.
They are not.
They are just slow framerates.
Nothing cinematic about a slow framerate.
The reason 24fps was used for cinemas was because that required less film while still being perceived as fluid motion by our brains.
You need quite slow shutterspeeds at 24fps, so that motion blur is what makes it pleasing (less sharp).
But you can make cinematic footage at 50fps as well.

Hello and thank you for your response.
I actually use slow frame rates (30 fps) since this camera takes better images at those fps (something about using a dual iso).
In general I have no problems at 30 fps, and I am slowly learning to make smoother movements, but in some scenarios where there are many bright objects (generally white) and I have to move the gimbal quite a bit, this happens. I use ND filters to try to comply with the 180 degree rule and achieve good motion blur.
I will continue investigating, thank you.
Greetings.

Is this the mini 3 Pro?

I have the Mini 3 Pro, no need to stick to 30fps.
The dual native ISO is not relevant to this problem.
You can achieve one of the native ISOs at 25,30,50 or 60fps
50fps is generally the best to prevent judder in PAL area (like Uruguay is)

Yes, it is the mini 3 pro, does it say that there is no big difference in quality between 30 and 60 fps? I did see that 60 fps videos are quite heavy. Another problem that I saw with 60 fps is that it does not allow zooming and that functionalities such as active tracking do not work at 60

Digital zoom is quite bad anyway.
Never use that.
I usually shoot in 2.7K / 50fps.
The quality difference is there, but not really important for me. Unless I am doing paid work.
And the files are much smaller.
Just look here. No judder, no flickering, nothing.
And good enough for Youtube quality.



PS, you really might want to stick to 25 or 50fps and ditch 30 / 60
You're in PAL area.
This matters when you are filming artificial lighting (streetlights etc. )
You could get flickering lights if you're on the wrong frequency.

First of all, thank you for taking the time to write and send me a video (the video is very good).
I understand that the PAL and NTSC affect more at night when the lights are on (I understand that during the day it shouldn't affect too much).
Probably what I'll start doing is filming at 50/60 in the city since that's mainly where the flickering occurs. In more open areas I can film at 30 fps without any flickering.
Although I do not do paid work, I am trying to make material as professional as possible, that is why I want to get the highest quality possible, but to be honest I do not know how much difference in quality there is between filming at 25-30 and filming at 50- 60

I personally would focus on the creative part of the job. How do you film stuff. What looks good. Which moves are nice.
If you master that part, your footage will get much better than a technical number can do.

Hello again, the other day I was watching your material, you have very good videos and it shows that you dedicate a lot of time to it. Today I made my first YouTube channel to start uploading my aerial videos (I only have 3 edited videos), maybe at some point if you have a moment you can stop by and maybe give me some advice or your opinion. Since both aerial filming and video editing are new, it is obviously very amateur material.
