These days it seems like everyone wants bigger and crisper pictures for their TV shows, movies, games and more. Four years ago, high definition or HD was pretty much the best out there. But now we've gone up to something called 4K which is even more detailed than before.

4K gives us images that look way sharper and realistic than regular HD could. You can see tiny hairs on people's faces, stitches in clothing, and blades of grass when watching nature videos. Text also looks super clear without being fuzzy at all. Some 4K movies and videos almost look real, like you could reach out and touch what's on screen. That's how insanely clear the pictures are compared to HD or lower resolutions.

Of course, all those extra pixels that make up a 4K picture instead of HD encoder take up a lot more data storage space and bandwidth to stream over the internet. That 4K movie you’re watching might be five times bigger as a file compared to the same movie in HD. And streaming a 4K YouTube video or Netflix show can easily use up 10GB of your monthly home internet data limit in just 30 minutes!

This boom in higher resolution media is creating some new challenges. Things like smartphone cameras can now record awesome 4K videos that gobble up storage quickly. Trying to fit a big collection of 4K movies or entire seasons of favorite 4K shows on a basic external hard drive just isn’t doable anymore with file sizes so large. Streaming in 4K over regular internet connections is also pushing bandwidth capacities to their limit.

This is where new video compression technologies come in to help keep things running smoothly. Compression is a way of squeezing down video file sizes so they take up less storage space and use less data when transferring over networks. By discarding unnecessary image information without reducing quality too much, compression lets us fit more content into the same storage footprint or data allowance.

The latest and greatest compression standard is called HEVC, also known as H.265. It was developed specifically to handle the enormous bandwidth and storage demands of ultra high definition content like 4K video and beyond. Compared to the still-widely-used H.264/AVC codec, HEVC provides around twice the compression capabilities which helps address the resource needs of higher resolutions.

In practice, this means HEVC lets 4K movies and videos take up only about half the file size that the same content would have when compressed using H.264. Yet the quality and detail remains practically the same between the two codecs. That huge 50% reduction in file size is a total game changer for things like our phone cameras, portable hard drives, streaming services and more. HEVC really extends how far resources can now stretch.

The battery drain and processing power required to playback 4K is also greatly reduced with HEVC compared to older H.264 video. Fewer processing cycles are needed to decode each frame, extending battery runtimes on mobiles. And lower powered systems that previously struggled can smoothly play ultra HD video with HEVC’s better efficiency. This future proofs our devices to keep handling higher resolutions to come like 8K.

Of course, the catch is that not every device on the market supports HEVC just yet since it's still fairly new. Most recent model TVs, streaming media players, game consoles and computers have HEVC built right in. But anything more than a couple years old likely only understands the older H.264 format instead.

That's where having an 4k
external HEVC encoder comes in handy. Encoders let you record or playback high efficiency video coding using the much more efficient HEVC compression format internally. However, they also simultaneously "transcode" the stream into the H.264 format on the fly so older TVs and media players without HEVC themselves can still view it just fine.

A great example of an encoder is the Elgato 4K Capture S+ device. It plugs right into your Mac or Windows PC over Thunderbolt or USB 3.0. Then you can select HEVC/H.265 compatible device as the recording or source format for small file sizes and quality preservation. Behind the scenes though, it also encodes a duplicate H.264 output for feeding to any display. This “two codec” system ensures maximum future-proofing together with full compatibility for all your existing gear.

As clarity of 4k visual and beyond takes over completely in the coming years,H.265 HEVC will become an essential piece of the puzzle. It allows the true potential of ultra HD and beyond to be fully unlocked without lagging connections or maxed out storage acting as a bottleneck. HEVC gets us to a place where higher resolutions can continue scaling seamlessly both now and later as requirements grow even further with technologies like 8K on the horizon too.

By standardizing on HEVC hardware and software that supports its compression benefits, we'll all be ready to enjoy the incredible details of bigger resolutions for much longer before needing an upgrade. So whether you love movie streaming, phone photography or crisp console gaming - HEVC is definitely worth exploring to maximize your true multimedia experience both today and well into the future of home entertainment!
