ENTER THE 4K

What is 4K? Well, it's the latest and greatest option in terms of video resolution of course! 4K video has more details than most of us can even take in all at once! There are details in 4K that you have never seen before and may hope to never see again! That’s why it’s considered ultra high definition. It definitely takes you up to a whole new standard of video production.

IT'S ALL ABOUT THE PIXELS!

Let’s start with a simple explanation of what 4K really means for PS/A and you. Display resolution refers to the number of distinct pixels in each dimension displayed on an image. If you are viewing a high definition video, it will be displayed in 1280 x 720p, which means that it is 1280 pixels across and 720 pixels high. To find the number of pixels in the entire image, just multiply these two numbers: 1280 x 720 = 921,600 pixels.

As technology progresses, more pixels are added to make image resolution more defined, which means that images are becoming more and more dense with pixels. The more pixels are in an image, the higher the resolution of the picture. While 2K images have over 2.2 million pixels, 4K images have over eight million pixels. The higher pixel density of an image makes it clearer and sharper because you can see more details of the image. If you wear glasses, you may find the shift from 2K to 4K similar to the experience you have when an eye doctor flips different lenses in front of your eyes and asks, "Is this better? or this? how about this?" The better, clearer image is always the one that allows you to see more details clearly.

Because 4K shows you twice as many details as can be seen in a 2K image, and four times the details of 1080p, 4K gives you a more impressive and immersive cinematic experience. The images are more lifelike and natural. Putting it another way, 4K gives you roughly 3840 x 2160, or four times the pixels 1920 x 1080 HD video. PS/A routinely shoots and produces in 1920 x 1080. 4K is another step up.

RUNNING THE 4K GAUNTLET

If you desire PS/A to shift to 4K for your project, you may run into several obstacles. One issue is the availability of displays. You and your audience will find it more expensive to buy a 4K monitor and TV. However, as it always does, the cost will go down as availability goes up. Another challenge is the availability of 4K content/ programming. However, 4K displays have built-in up-conversion circuitry that can translate any video signal that you feed into 4K resolution.

It’s also more difficult to shoot 4K video. Most video cameras can produce 1080 without any problems but don’t have the power or the sensors that are needed to shoot such a high resolution video. So if you want to make a high bit-rate, high frame rate, and high resolution video, you are going to need a camera that is up to the task, consider additional lighting needs etc. Just like high speed cameras, we have the 4K cameras that will do the job, but the cameras, additional equipment and operators cost more.

In our following articles on 4K, we will be helping you navigate the world of 4K production including tricks, techniques and cameras that will have you rocking the 4K world like a boss.
