My 4k Footage looks blurry to me does anyone else agree?

So this was filmed on my P4P in 4k, cant remember the fps but its high. Edited on iMovie. Exported as 4K, on pro res, and the footage was taken straight from the SD. just looks a little blurry to me and I dont get why, other footage ive seen from other p4ps looks crisper any ideas why?

sample here

What other camera settings did you use? List how everything is set.

Shutter speed, ISO, FPS, WB, sharpness, etc.

It is blurry and its looks to be a possible codec problem when its rendering out. You can really tell by just looking at this in 1080 so try something else other than I Movie.
We use a mac with Adobe Premiere - or Final cut X pro and there is a difference between Vimeo Codes and Youtube Codecs but I movie raises the red flag for me so that would be my first check. How does the video look when you just play it from the SD card. ?
