Not so long ago, HD was the gold standard in video quality. Everyone was clamoring to get the latest HD television or smartphone with an HD screen and camera. Then came full HD, and creators upgraded their recording setup to pump out videos at 1080p, but soon, even that wasn\u2019t enough.<\/span><\/p>\n Sharp images weren\u2019t enough for audiences. They wanted crystal clear, almost lifelike images, so the norm has shifted again, and today, viewers expect their content to be in <\/span>4K video resolution<\/span>. Consumers are always ahead of the curve, so a recent report shows that <\/span>80% of Americans owned a 4K TV<\/span><\/a> in 2024. Ultra-high definition is no longer a luxury \u2013 it\u2019s the expectation. Why would anyone watch lower-resolution videos when other creators currently use <\/span>4K video for live broadcasting<\/span> and other types of content?<\/span><\/p>\n 4K streaming is no longer just for high-end studios or specialty productions. Everyone can do it \u2013 so why wouldn\u2019t you? Join us as we explain what 4K is and what it will take for you to start <\/span>4K live streaming<\/span> and <\/span>broadcasting online<\/span><\/a> as well!<\/span><\/p>\n Before getting into the benefits of 4K for creators and audiences, let\u2019s cover the basics first. Why don\u2019t we start by explaining what <\/span>video resolution<\/span><\/a> is: Resolution is the number of pixels the image on the screen has.<\/span><\/p>\n Ok, then what are pixels? They are tiny squares of illumination that, when grouped together, make up a picture. The more pixels in that picture, the clearer and more detailed it is. To figure out how many pixels an image has, we must look at its width and height. This is known as the <\/span>aspect ratio<\/span><\/a>. For example:<\/span><\/p>\n As you can see, 4K resolution has four times the pixels of full HD resolution and nine times more than standard HD, which is only 1280\u00d7720. The significant increase in pixel density results in greater clarity, even on large-format displays such as big screens or stadiums, even during close-up shots in live events.<\/span><\/p>\n It also eliminates the dreaded \u201cscreen door effect\u201d that sometimes happens with lower resolutions. A video with good resolutions has:<\/span><\/p>\n Because 4K produces such high-resolution images and videos, <\/span>live streaming in 4K<\/span> is a bit more resource-heavy. So, <\/span>how much bandwidth do you need to stream 4K live<\/span>?\u00a0<\/span><\/p>\n You\u2019ll need an upload speed of at least 25 Mbps, and the recommended bitrate for 4K live streaming is between 13-34 Mbps, depending on the frame rate and content complexity. For a 30 fps stream, the bitrate can range from 13\u201319 Mbps. For 60 fps, it can go from 20\u201334 Mbps.<\/span><\/p>\n But what if you, as a streamer, have a slow connection?\u00a0 <\/span>Can you live stream in 4K with low bandwidth<\/span>? Unfortunately, the answer is no. You need a high-speed connection with a high data rate to transmit the amount of visual information that 4K produces. There might be a few workarounds, like aggressive video compression, but that will affect the quality.<\/span><\/p>\n Besides the bandwidth and upload speed, to stream videos in ultra-high definition, you\u2019ll need a <\/span>4K streaming platform<\/span> that can handle the high demands of such content. For example, Dacast\u2019s <\/span>live streaming platform<\/span><\/a> with <\/span>adaptive <\/span>bitrate streaming<\/span><\/a> lets you upload and stream in 4K while adjusting the video quality to the viewer\u2019s internet connection.<\/span><\/p>\n So, what makes 4K so special? Once you\u2019re used to it, it\u2019s immediately noticeable when something isn\u2019t in 4K. The jump in video quality is significant, and audiences expect nothing less from their favorite content. Here are some key features that make it the perfect choice for live streaming:<\/span><\/p>\n Even if, statistically, most of your audience still watches your content in 1080p, they will upgrade sooner rather than later. The global 4K display market is projected to exceed $800 billion by 2034<\/a>.<\/span>\u00a0It\u2019s better to switch to 4K now to keep your content relevant and compatible with future technologies, including 8K displays.<\/span><\/p>\n Besides, converting 4K resolution into 1080p is much easier than doing it the other way around; downscaling from a higher resolution to a lower one (like 4K to 1080p) results in a better-looking image than upscaling from a lower resolution to a higher one (like 1080p to 4K). Your audience won\u2019t have any issues watching your live streams and broadcasts, even in 4K.<\/span><\/p>\n So, <\/span>is 4K better than 1080p for live video<\/span>? While video quality in 4K is much better than in 1080p, the streaming requirements are also greater. A higher resolution requires more bandwidth to transmit because of <\/span>larger file sizes<\/span><\/a>.<\/span><\/p>\n It demands more bandwidth, which might be a challenge for viewers using slower internet connections. On the other side, broadcasters need higher encoding settings, like the H.265 (HEVC) or H.264 video codec, and more powerful hardware to deliver 4K content smoothly. Here is a quick <\/span>video resolution comparison<\/span> of the most used resolutions:<\/span><\/p>\nTable of Contents\u00a0<\/strong><\/h2>\n
