What’s 4K? It’s the current trend for ultra high-definition video, also known as 4K UHD. 4K UHD typically has a resolution of 3840×2160 which is 4x as large as 1080p HD. Aside from high end monitors and new TVs, most don’t view content in 4K (yet!). YouTube hosts and delivers in 4K, but again, most experience it scaled down and re-compressed to the resolution of their viewing monitor. If few can watch 4K natively, why is it so important?
It’s important because it gives flexibility when you deliver at more commonly viewed resolutions like 1080p HD. It gives flexibility to crop without having to zoom in on the final framing. By selectively editing between the wider screen framing and the cropped view, it ends up looking like there is a second camera trained on the same subject from a single camera shoot.
It also allows cleaner camera stabilization. When footage is stabilized or straightened in post-production, the editing software must zoom in a small amount to cover up some trimmed edges. If 1080p footage is zoomed in even a tiny amount, some resolution is lost. 4K can have three quarters of the final image thrown away with zero loss in resolution if the final output is HD.
Finally, when 4K is scaled down to HD the final result is much sharper than if it was shot originally in HD. That is because as the resolution is shrunk it has more data than it is showing in the final product – and everything looks sharper and finer.
Having said that, if we didn’t end up cropping any scenes we’ll always deliver in 4K when possible. It’s the ultimate future-proofing for when more 4K-ready monitors are available.
Teskey Mediaworks shoots everything in native 4K all the way from camera to final delivery to give ourselves the maximum quality and maximum flexibility whether delivering in 4K or HD.
