Found this on another forum. Maybe it'll answer some questions.
First of all to play 4k you must record in 4k - silly I now but this means it writes lots of data. More than the other formats, so the file is much bigger.
So with this mass of data you need three things to play back such video
1 a 4k screen of sorts - usually a tv. A monitor will do but does yours support 4k?
2 The right codec to process it, most newish programs have this or it is a question of updating such on your computer.
3 Biggest issue , a computer that is big and fast enough to process it. The slower the machine the longer it takes to process.
Sounds simple doesn't it but if only was.
If you have a modern computer with a fast chip then you stand a good chance. Likewise if you use a Cyberlink program or VLC or Divx etc. just ensure you have updated the codec for 4k. (suggest check updates / visit the site)
Even if you have a MAC you just need to check it has all the latest updates and it is very likely you will be ok.
If you have an old machine then I suggest record in 1080 or there abouts and you will still get great video.
As mentioned in other posts its great having 4k but there is an ongoing requirement that a lot of members may not have to hand at present.
Maybe Santa will bring ?
