I'm also very interested in what smart phone j.f.r. is talking about! Haha! From my experience the NX1 is incredible! and Mattias Love your footage! BTW.

It's just upscaled. 
I did some tests a while back that showed that youtubes compression is so bad that hd upscaled and 4k looks pretty much the same.
But when upscaled youtube enables three times the bitrate and when viewed in 1080p the resolution is back to normal but you still gained the higher bitrate. 
Same with good HD from the bmpc and 4k downscaled, on youtube it looks the same.

I always go for the old saying of "One good zoom and lots of primes". And Im a vintage lens horder so naturally I recommend getting couple of those as well. For the NX I have some Konicas and m42.
Here is a quick test I did with a Yashinon 50/1.9, that I payed 10 bucks for, as well as a Yashikor 200/3.5. I think they give a funky look that can be handy for some more artsy stuff.
