Hey all:

I've been testing my OSMO for the past couple of days and it seems my 4k resolution is grainy - not as sharp and crisp as it should be.  I'm even on the fence with 1080p.  I also own a P3A and film in 2.7k and see a vast difference -- so nothing to do with my Macbook Pro.

Here are the specs I'm using to film:

4k @ 24fps
.MOV format
NTSC (test PAL) as well.

Any ideas?  

Did you set 60Hz option? Mime came set on 50Hz. Same menu where you set NTSC. Also did you try MP4?

Tested MP4 with no change. I'll try setting to 60Hz. Thanks for the tip-

Can you upload some test videos from the sd card? We need to analyze the original files.
