What’s all the fuss about 4K video?
Just as 1080p and 720p were becoming the norm in high-definition, 4K has now arrived to the scene. So what is it? 4K or ultra HD which it may be referred to in some circles is related to video resolution and clarity. It’s measures in pixels and is capable of 3840 x 2160 ppi or 4096 x 2160 ppi (pixels per inch). For the most part 1080p and 720p resolutions still look great on most viewing devices. The differences in resolution and quality will mostly become clear when viewing material on a large TV or projector. Its worth noting that recording in that format will take up a lot more storage space. For this reason we may see the format held back on some devices until greater storage is available or newer video compression technologies are made available.So what does this mean for you? The majority of high-definition video production already supports 720p and 1080p. 4K is the next step up in terms of visual quality and file sharing sites like Vimeo and YouTube will see more videos uploaded in this format.Devices shooting 4K used to be reserved for big Hollywood budgets and out of reach for most people. Now Smartphones capable of shooting in 4K are hitting the market including Samsung’s Galaxy Note 3 with others soon to follow. It’s only a matter of time before you see most amateur, semi-professional and professional video cameras supporting the format. You will most likely hear the big push coming from TV manufactures. To them it’s really a numbers game and new line ups of 4K televisions will be promoted in a fashion to make your existing 1080p or 720p television feel old.
4K Advantages – The Zoom Factor
4K can offer a lot of advantages during the post production process, especially if the need is an output 1080p or 720p video. 4k footage has more pixels allowing for footage to be zoomed on a subject without losing a great level of detail. In the example above, the videographer could zoom on one of the mountain peaks while still maintaining a high level of clarity.
In the example below the footage is captured in 1080p followed by a zoom of one of the mountain peaks. Unlike the example above, there is a greater risk of image quality being lost because you are limited to the original resolution captured.
What\’ s Next for 4K?
Most newer models of semi-professional and professional video cameras will be offering 4K. While Samsung’s Galaxy Note 3 has already jumped on the 4K bandwagon, it may take a few more years for the technology to become mainstream. The new GoPro Hero 3+ Black Edition is also capable of filming 4k videos. GoPro’s Hero 3+ Black Edition is so versatile that it’s be used underwater and has been used to capture incredibly cool action footage. Lets just hope we get time to digest 4K. Believe it or not, 4K may have live a short live once 8K becomes the new talk of town.
