So the videos Ive been taking recently on my P4P have been super grainy and seem to be low quality. Also seems to be a lot of "noise" in the videos as well. My video quality on the P4P is always set at 4k at 30fps. The computer Ive been watching all my videos on is a 2012 Macbook Air. Is it the camera on the P4P that is shooting low quality video or is it my computer lacking the capability of displaying quality video? Im gonna try using my girlfriends brand new Macbook Pro tomorrow to see if the video quality is better on that but it just doesnt make any sense because Ive shot lots of video and watched it on my macbook air plenty of times and it always seems to be good quality video until a few days ago. Maybe Ive got the camera on a setting it shouldnt be on? Please let me know anyone.

You have the same issue for all the recorded videos?
Would you please upload the original video directly from SD card, and do not edit it to dropbox then provide us the link?
