4K, or UHD is all the rage right now. So what is all the fuss about? Well, the resolution of UHD images is absolutely gorgeous! If you need convincing just walk into any electronics store and take a good look at the 4K ready monitors and the demo material Sony, Panasonic and many others are peddling now.

But other than beautifully crisp images there's a very good reason to start upgrading at least one or two of your HD cameras to UHD soon. Most of us edit 1080p HD projects and output that as well. At either 3840 x 2160 pixels (4K/UHD) or 4096 x 2160 pixels (Cinema 4K) 4K provides images that are much bigger than the standard 1920 x 1080 HD. And how does that benefit any videographer who still works in 1080 HD? 

You can now reframe your footage without losing resolution: 

In this example Avid's FrameFlex feature allows me to reframe a 4K aerial clip shot with a DJI drone to centre building 22 in the frame. Add some grading and an edge focus effect to give it a trippy "tilt-shift" feel, and you've got quite a nice aerial shot going there.
