Shooting in 1080p 24fps is much cleaner n less noisy than 4k. 4k may have more detail but its so noisy or maybe too much data to be written in the card but cant be consistent. Shot some vids at night and boy i was so disapointed wid 4k. 1080 on the other hand im happy about shooting at low light. Coming from a p3p to p4. Really disapointed with the camera. Im using sandisk extreme pro on a 55 inch 4k tv. I never use 3d noise reduction also as it adds an effect wen u yaw. My 4k vids also stutters from time to time maybe cozof a high shutter speed in the bright day light? Let me know wt u guys think.
