SD vs HD – What Are The Differences?

SD vs HD

Whether you’re watching a live stream of your favorite Instagram influencer or creating a video project for your university, one question more often comes to mind: which resolution is best for the videos? This leads to another question: what is hd vs sd? Is there any major difference between these two?

Today, creating videos and going live is a common marketing tactic used by many businesses and brands across the globe. Suppose you have created a video for a client consisting of blurry images, pixelated faces, or other objects. These things will totally distract the audience from the message you want to deliver. It can ultimately affect your business or brand. This is why creating a high-quality video is crucial.

If you’re still confused about whether your video quality should be high or standard, this post will help you. Here, we have explained the common difference between SD vs. HD.

Let’s begin.

What is SD?

SD or Standard Definition is a video resolution of 480-pixel. SD resolution has been popularly used in television broadcasts and displays for several years and is still useful in live streaming. It is still considered the base resolution level for live streaming and broadcasting.

This is why even today, many camcorders, digital cameras, and even some Televisions have SD resolutions. Of course, there are lower resolutions like 144p, 240p, and 360p in which you can stream, but you should not go below SD at 480p for streaming.

What is HD?

HD or High Definition is a higher resolution of 720 or 1080 pixels. Today HD resolution has become the standard streaming industry resolution. From playing YouTube videos to streaming other websites, HD resolution is a widely used streaming format for internet videos.

The 720p High Definition is referred to as “Standard HD,” and the 1080p High Definition is termed “Full HD.” Most often, 1080p HD is used to stream or play high-definition videos on social media channels.

SD vs HD: The Difference

Both SD and HD have their own benefits and drawbacks. Let’s take a look at both:

  • The SD would be a great option for the lower inter bandwidth or upload situations. So, you can even stream or upload videos at a slower internet speed.
  • The Standard Definition (SD) has Television refresh rates of 25, 29.97, and 30 fps. This is why you’ll get a blurry or low video quality with low file size and bit rates.
  • The SD resolution also allows you to stream videos with less buffering.
  • HD or High Definition offers better videos in high quality. With a pixel height of 1080p or 720p, you can enjoy watching videos on your favorite streaming platforms without buffering.
  • You must consider the bandwidth whenever you want to stream in SD or HD. For example, for 720p resolution, you must use an internet bandwidth of at least 2.5 Mbps. On the other hand, if you want to stream at 1080p, you must have upload speeds at least double the 720p resolution.


HD or High Definition provides high-quality streaming, and SD or Standard Definition has a low-quality video experience. However, HD is way more expensive than SD. So, if you have a budget and no bandwidth issues, you can definitely go with HD, and if you don’t, the SD will be a better option for you. Now you know what is hd vs sd, so pick the best resolution for streaming and broadcasting.
