Video resolution high standard definition

Resolution has an overall effect on the image quality of videos. The higher the resolution, the clearer a video will be. Resolution also affects the file size of videos. Because of this, a High Definition video has a bigger file size compared to a Standard Definition video with the same duration.

With smartphones, DSLRs, and monitor brands racking up on 4K and even 8K offerings, having a good understanding of the basics of video resolution is timely. Moreover, video makers need a good understanding of this basic concept. From shooting, all the way to uploading videos online, video resolution is an option in the menu that affects the viewability of our content.


The dimensions of video resolution

Video resolution is measured as width by height using pixels as units. Pixels are tiny squares that make up a digital image. For example, a 1920 x 1080 video means the width has 1,920 pixels and the height 1,080 pixels.

The image above shows how more pixels make the image sharper and more detailed. To put it simply, more pixels make up better image resolution.


Current video resolution standards

The video resolution presets that we have seen in our camera or computers are actually standards determined by major video manufacturers and broadcasting companies. The most common video resolution today is High Definition (HD) 1920 x 1080. Smartphones and DSLRs made in the past ten years should be able to shoot in this resolution. 1280 x 1080 video is the minimum standard for HD. The video resolution of tape-based mini-DV cassettes back in the days of camcorders was Standard Definition (SD) 720 x 480.

Ultra High Definition (UHD, popularly known as 4K) 3840 x 2160 video resolution is the shooting standard used for most professional scenarios. Smartphones capable of shooting in 4K are also becoming popular these days. To learn more about uploading 4K video to online platforms, read this guide.

The table above shows that as video resolution becomes bigger, the file size also increases. Users out in the field, like journalists and video for change practitioners, should consider the availability of high-speed mobile internet if they are to upload video content remotely. If the signal is bad or mobile data is limited, it’s a good decision to shoot in HD rather than in 4K resolution. Users can also compress video to make file sizes manageable.
