iPhone 12 camera flicker on video recording

Hi!


I recently bought the new iPhone 12 Pro Max.


I have noticed that when I shoot video's in the dark (with the lights on in the house), there is some kind of flickering visible in the video.


Apparently it is possible that due to very fast flickering of lights, slowmo video's make this kind of flickering visible when you can not see it with the naked eye.


I however have this problem with normal video's as well. I have compared it with the video's on my iPhone X and it is definitely worse in my iPhone 12 video's.


I noticed that this happens while recording video on HD (or 4K) at 60 FPS, if you switch to 30 FPS this doesn't happen.


Anyone else that has this problem?


Thanks!

iPhone 12 Pro Max, iOS 14

As for the issue of light flickering, studying a little this whole issue I have been able to verify one thing.


This only happens to people who live in countries with PAL format (like Spain), where artificial light works with FPS multiples of 25. In many other places like the US it does not happen because they work with FPS multiples of 30.


I have downloaded the RCam app, which allows you to vary the FPS and I have been able to verify that in video recording with 30FPS and 60FPS this flickering of the light occurs when recording video, which does not happen if I set the recording to 25FPS or 50FPS.


I know Apple is going to introduce 25FPS recording and would ask if they can introduce 50FPS in the future for better and smoother recordings.


Setting the camera's FPS to 25FPS or 50FPS eliminates this problem. so... PROBLEM SOLVED!

Hola! Tengo un problema similar con mi Iphone 12 Pro. Los videos a plena luz del día parpadean de forma casi grotesca, algo que se nota especialmente en el cielo azul y en las zonas iluminadas por el sol. Sucede cuando grabo mientras ando, pero no cuando estoy quieto. Hice una prueba con la app Camera Pro en modo manual (ISO y velocidad fijas) y el problema continúa, lo que lleva a descartar que el origen esté en las variaciones automáticas de esos parámetros. Conviene aclarar que este parpadeo no es el habitual que se da en las grabaciones hechas con luz artificial de 50mhz de frecuencia, que no se empareja con el modo NTSC del Iphone, pensado para una frecuencia de 60 mhz.

Espero que sea un tema de software, ya que, de lo contrario, lo devolveré y pediré el reembolso de lo que he pagado.
