Grainy footage especially when recorded 4K

Hi Team,

 

Though i have latest firmware version V02.01 installed in my Gopro when I tried recording 4K vedios with my new Gopro Hero 6 Black camera footages came out grainy. Please help me in getting this issue resolved.

 

I have noticed this issues sometime in 1080p footage as well but it is rare in that version. In 4K everytime i shoot i get grainy footage.

 

Thanks and Regards,

Sathwik Reddy G K

Low light problem. The grain is caused by the lack of light in the video you posted.

With the correct settings and editing software you might be able to get the same results.

Re: Grainy footage especially when recorded 4K

the grain is result of low ISO (ISO is inverse so 100 is high - excellent lighting conditions, 1600 is low - low light).

 

To avoid high ISO try 400 and reduce the shutter speed to 1/20th. This can and will cause motion blur.

 

Personally I haven't tried it in low light yet so I don't know what the results and best seting would be. I also don't have my camera to hand, so I'm not sure what all the settings for ISO and shutter speeds are.

Huh? 

 

High ISO in your example is 1600. Low ISO is 100. ISO on digital sensors is a sensitivity rating. The lack of light in the scene causes the GoPro to increase the ISO which in turn causes the grain he is complaining about. The 6 Black goes all the way up to 6400 ISO if you let it. There are hundreds of videos explaining this on youtube with almost every digital camera. There are also many ways to reduce or eliminate the grain(actually noise) in videos. General rule of thumb is the small sensors in action cameras are not good at low light. Some better than others. I would suggest watching a few videos on the subject and then testing it for yourself.
