+$In 2017, we’re seeing more and more video on websites, and that’s not surprising.+$grabs visitors’ attention faster than any text or still image can, and it generates the kind of emotional response that every website owner craves.
+$Our eyes are naturally drawn to unexpected movement. We can't help it; it’s part of the biological programming that evolution has designed for our brain.
+$And that’s why more and more designers are using video as an integral element of their websites, whether an attention-grabbing， 一个+$, a strategic use of+$in place of still images, or a combination of these.
+$But now there’s a new trend in web video that everyone working in design needs to get on board with, fast, or risk getting left behind: 4K.
+$4K is a very high resolution video that’s so-called because in terms of pixel resolution, it’s essentially four times more detailed than HD (high definition) video. For this reason, it’s also known as UHD, short for Ultra HD.
+$There’s some quibbling amongst techies about exactly what qualifies as ‘true’ 4K, but from the standpoint of the viewer it basically comes down to a very high quality, intensely realistic picture.
+$Once you’ve seen 4K video a few times, it’s difficult to watch standard video again with the same sense of enthusiasm as before.
+$Remember when you first watched HD, and how jolting it was to go back to SD (standard definition)? Or if you’re old enough, what it was like to watch a VHS video again after being introduced to DVD? The same principle is going to apply with 4K.
+$In other words, as more and more consumers get 4K-capable devices, the race will be on to supply them with the kind of high-resolution imagery they’ll increasingly demand and respect.
+$Right now, the video-based header, background or snippet on your website looks fine on ordinary devices. But the speed at which people upgrade their hardware these days (often free under the terms of a mobile contract) can be quite staggering.
+$So it won’t be long before your website runs the risk of looking outdated, clunky and old-fashioned.
+$However, creating new video material in 4K involves a lot of expensive equipment, not to mention film-making know-how. So where can you get new, 4K-ready footage to keep your sites up to date and on-brand?
+$Quality And Quantity
