Hi All,


After I used DJI Action4 for a while, in Low Light night situation I use the following settings that seem to work well.

4K   30 FPS    RS
Pro Mode Exposure Manual (M) ;       Color Normal
Shutter Speed 1/100 Sec (or 1/120 for 60 Hz Country)
ISO  100 - 12800


Then Press "Confirm"


All Sample Clips Out of Camera without Post Processing.


When you use DJI Action 4  on Day time, please don't forget to set Exposure back to "Auto"

Thank you, this will help.

Thanks for the tips

tips are great, but light always changes

Do you not use the built-in low-light option?

Which built in there are two if not mistaken, priority low and auto low

Either, i was just wondering if the OP used it at all.

Yes, light always changes.

In this setting;
The DJI Action 4 will keep Shutter Speed at 1/100 Second. So EIS can maintain sharp video.
When light changes, DJI Action 4 will change ISO Automatically from ISO 100 to ISO 12800.

By the way, we cannot use this setting in Day Light. Because Shutter Speed which fixed at 1/100 Second and Lowest ISO 100, still Over Expose the video clip.

That why we should not forget to set it back to Full Auto when take video in Day Light.


Cheers

Yes, I use Built-in-low light option by set Low-Light Image Enhancement to "Auto" in PRO Mode.

When light level is low, DJI Action 4 will Activate Low-Light Image Enhancement Automatically.
You will see this message when press Record Button to start record video clip.


Cheers,

Thank You very much for your comment.

I hope you enjoy use it when low light in this setting.

Do you mean "EIS Priority in Low Light" and "Low-Light Image Enhancement"?

If it is;

"EIS Priority in Low Light" is Active in "Default Mode" of DJI Action 4.
You can set it to "On" , but it is not effect anything when you use DJI Action4 in "PRO Mode"

"Low-Light Image Enhancement" is Active in "PRO Mode".
When you use DJI Action4 in "PRO Mode" and setting as show in the clip above.
It will help Low light video clip as you see in the samples.


Cheers.

In Dark, Low Light situation, I can see that "Low-Light Image Enhancement" deliver clear video image and less noise. (When Shutter Speed is 1/100 Second, and ISO above 1600)

But if the light is not very low, noise is not too much, we can hardly see the different.

the OP did answered.

and thanks OP we appreciate the  advice

I hope you enjoy this setting.

I'm sure I will if I ever get an action 4

Just wondering if you have any jitter issue with your current settings.

My settings is kinda like this.
4k25/HB (25Hz for my country)
Shutter 1/100-1/8000
EV -0.7
ISO 100-3200
WB 4500k

No, I have not jitter issue in the video clips. You may see that in sample clips in my post.

For your settings, I think 4K 25 FPS may cause the jitter. I use 4K 30 FPS, which help smooth video clip a lot.

I also live in 25 Hz country, when we set the Shutter speed to be 1/100 Second, it will synchronize with 50 Hz light bulb. Number of Frame Per Second did not cause 50 Hz light bulb to flicker, but Shutter speed did and this is not Jitter in the clip.

You can see Jitter when Frame Per Second is Low (24 FPS, 25 FPS) more than 30 FPS, especially when pan the camera or any fast moving object in the clip.

So Shutter speed 1/100 Second and 30 FPS will smooth video clip (Reduce Jitter than 25 FPS) and synchronize with 50Hz lighting bulb (No Flicker). If you still got jitter video clip, you may try setting to 50 FPS.

Setting 30 FPS, 50 FPS or 60 FPS did not reduce light to reach the camera sensor, because we set Shutter Speed to 1/100 Second. The video clip will be look exactly the same brightness. But Higher Frame Per Sec will help smooth video clip (Reduce Jitter).

hi, can this configuration be good for going around with go-karts at night? Thank you

It is not good for Go-karts at night, because shutter speed 1/100 second is too slow for Go-karts movement.

I think shutter speed 1/640 second or 1/1000 second may be good enough, but at night, it will be very dark for that shutter speed at night.

By the way, you may try setting Shutter speed at 1/640 second. If the Go-karts track is well illuminate, it may be bright enough for recording.

But recording Go-karts at night is very challenging situation for every camera, including very expensive one.


Cheers.

hi, theoretically the track should be well lit. so which complete configuration do you recommend? this is a idea:

4k 30 fps RS (can i use a RS+?)
Exposure M
color normal (can i use dlog?)
SS 1/640 or 1/800 or 1/1000(what happens if the shutter speed is too high?)
iso 100-12800
fov Standard (can i use wide?)wb: auto

4K 30 fps RS should be OK, I am not using RS+ because it will crop field of view more.

Exposure M ;  Color normal is OK.

If you use Dlog, you should perform Post Processing, but it can deliver better video clip.
Dlog Post Processing is a lot of work for me to do, so I always use normal color.

If the track is well lit, You may start SS 1/640 sec, if the video clip is not too dark, you can try 1/800 sec.
Using very high shutter speed will deliver very dark video clip.

ISO range 100-12800 and Standard FOV is OK.

If you can try it in advance at Go-karts track, you can try 1/640, 1/800 and 1/1000 sec.
Then you can select the suitable setting that work for actual light level there.


Enjoy you Go-karts,
