I have just bought a 7 Black and tried taking some video in a good lighting enviroment in a fuction hall in the evening but turned out not sharp. I thought it is suppose to be 4K. How come ?

Was the camera still or were you walking about? A common cause of blurred images is that to cope with lower light the shutter is held open for longer. If we walk around shock from our steps physically moves the csmera( and therefore the sensor) while the shutter is open causing streaks of light in the image. This is on the sensor and happens before stabilisation. It is nothing that the stabilisation can fix

Lighting is Key. you do need light and it all depends. If Protunes is used you must drop Sharpness from Default (high) to medium) GoPro never fixed. that Like said before we al lguess a video is helpfu. if to private then we will wait for a sample.

Hi Thank you for the response.
I still find the Gopro not that fantastic esp for night video and photo. A bit disappointed as I have gone thru all the other settings. May be there is something which I may have missed out. Could it be Gopro being for action video and photos is not good for taking nitght shots. As for 4K I cant even save for viewing and other device. Kindly advise

This is down to two things. Firstly with most action cameras the aperture of the lens tends to be f/2. 8 or there abouts. This is a slow lens and let's in half the light of f/2 and a quarter of the light of a f/1.4 aperture. The reason that f/2.8 is used is because the faster the lens the shallower the depth of field and action cameras a need a deep depth of field to get everything in reasonable focus.
The second is. The sensor size. Action cameras use a small sensor. The smaller the sensor then the smaller the pixels and the smaller the pixels the less light each one has so they need higher light levels to begin with. Micro four thirds have sensors with a surface area 10 times larger than the sensor in the gopro and even these cameras are generally considered to be poor in low lights. Cameras with good low light performance will tend to have large sensors probably full frame or large format.
Gopros aren't designed to be great low light cameras, although in the right conditions and with the right settings can do OK.
I'm not sure about the problem you have with 4k on other devices. Do those devices have the h265 HEVC codex for Playback?
