If you've been shopping for a camera recently you'll probably have seen the term '4K video' plastered on shop displays and even written on the labels stuck on the front of products. 4K is a video specification that literally just means '4,000'. It gets its name from the approximately 4,000 pixels of width of the footage.
The name 4K is used to describe a couple different, though very similar, standards. The form you're most likely encounter is Ultra High Definition or UHD, the new standard for 4K television. 4K video is poised to become the new benchmark for both recording and watching video and it brings a whole host of benefits, right away.
The images below represent the difference in details between various video resolutions. Video captured using a Panasonic LUMIX DMC-LX100.

Some modern digital cameras offer slow motion video at this resolution.

Few cameras offer 4K video recording but when you can, the footage is incredibly sharp compared to 1080p. Read on for more details why.
If you shoot HD video, should you upgrade your camera to a 4K-capable model, even though many people still don't have a 4K TV? The obvious reason to make the switch to 4K is to future-proof your work.
Consumers may not demand 4K content today, but at some point they will, and if history is any guide this will probably happen soon. Just imagine if you had continued to shoot in standard definition up until the moment that everyone finally had an HD television. Who would want to watch that crunchy, mushy low-resolution content today? As a content creator you're always better off getting ahead of the curve.
However, even if you don't need (or want) to create 4K content yet, there are number of huge benefits to adopting a 4K workflow now.

How could a video mode ever be useful for stills photography? Well, think of it as a way of shooting 24, 25 or 30 eight megapixel images per second and you might start to understand the appeal. Whether it's a child's brief smile after blowing out their birthday candles or a match-winning goal being scored, this shooting speed can help make sure you capture the perfect moment.
Many current cameras let you extract frames from video footage in playback mode, and some let you hit the shutter button during recording, to mark out which frames you want to grab.
Several Panasonic cameras take this a little further with a dedicated '4K Photo' mode that lets you shoot footage in more conventional aspect ratios, rather than being locked to the panoramic format of most video. Some cameras also include clever functions to help you capture the moment, such as a pre-record mode that constantly records footage, then saves the 30 frames before and after you hit the shutter.
It's entirely possible to pull great images from 4K video from any camera, but if you're shooting video with the explicit intent of getting stills, your images will benefit from some fine-tuning of settings and technique. As always in photography, time spent experimenting is not time wasted.
As great as 4K is, the extra resolution might mean that you'll need to upgrade parts of, or potentially all of, your production pipeline. This might include memory cards, displays, hard drives, computers, and possibly even lenses. Below, we'll take a look at how to prepare for a 4K world.
Manufacturers of both consumer and professional electronics are scrambling to add 4K video to their products, but with more pixels comes an awful lot more data to push around.
4K footage takes up a lot more space than full HD - up to four times more, in fact. A single minute of video on some prosumer 4K-capable video cameras can weigh in at more than one gigabyte.
In order to keep up with all that data, you'll need fast memory cards, capable of at least 30MB per second write speed (which corresponds to the U3 rating on SD cards). This should allow recording at quality settings up to around 200mbps.
Memory cards aren't quite as expensive as they once were, but high-speed cards still represent a significant investment, and one that needs to be factored in to the cost of a new 4K-capable camera.
Storing all that data for editing also means a fast, high-capacity hard drive. You'll need at least a 7200rpm conventional hard drive on a USB 3.0 or faster connection, and as much storage as you can afford. Solid State Drives (SSDs) are significantly faster than spinning-disk drives but they're much more expensive per GB of storage.
It depends. In the same way as 4K video requires a lot of space to physically store, it also requires a lot more processing power to handle it when it comes to editing the footage.
As always when looking at computer performance, the main things to consider are processor speed, the graphics card, how much RAM is installed, and the type and capacity of hard drive.
You'll soon know if your computer isn't up to the task of editing 4K video. But even if you're having issues, you may be able to get by editing proxy footage (offline) as opposed to the actual original footage (online).
It is possible to shoot, edit and publish a 4K video project without ever viewing the footage on a 4K monitor, but we wouldn't recommend it.
If you're looking for a single monitor workflow, expect to spend at least $500 and keep an eye out for the 'IPS' designation. IPS panels are superior when it comes to color accuracy at different viewing angles. If you already have a color-accurate monitor, you can go with an additional, more budget-oriented 4K monitor for cutting footage together, and continue doing color grading on the older monitor.
Editing 4K footage doesn't just require a powerful computer, you'll also need specialized video editing software.
There are plenty of video editing suites out there, and 4K support is becoming more common even for inexpensive options like Apple's iMovie. But for the best results we'd recommend more full-featured software like Adobe's Premiere Pro, or Apple Final Cut Pro X. Just be aware that different cameras shoot video in different ways, and different video editing software interacts with these file formats in different ways too, so you should do some research to find which software will work best with your footage.
Let's say you've produced your prize-winning 4K content and are ready to share it with the world. Great! But before you do that, here are some things to think about.
If you want or need to share your work in full-resolution 4K you can easily share the files directly via your prefered online cloud storage service, but depending on your Internet connection speed, upload and download times will probably be very lengthy. 4K video is still not very well-supported by online video hosting services, but Vimeo allows you to make 4K footage available for download and YouTube offers 4K streaming (albeit highly compressed).
Finally, consider: do you even need to output in 4K? As we said in the introduction to this article, HD video is great, and it's fine for most purposes. There are some huge advantages to shooting and editing 4K, but when it comes to sharing your work, 4K might be overkill. If you output as HD, file sizes will be significantly smaller for one thing, and you won't need a UHD screen to view the footage at its full resolution. Even if you output HD though, you should always save a 'futureproof' full-resolution 4K version to disk.
