Resolution is the number of dots or pixels used to display an image. A higher-resolution video will have a clearer image because the number of pixels is higher, having higher pixels gives a better-quality video.
What is resolution?
The number of pixels present in your video frame is called resolution. These pixels are very small normal human eye can’t see them. The resolution is measured by the number of pixels and the higher the resolution the clearer the picture Or video.
It is measured by the number of pixels In the standard 16:9 aspect ratio. It is common for computer monitors and television sets.
Some of the common resolutions are such as 1080, 480,1440 and 720. Resolution is typically specified as width and height, It represents the number of horizontal pixels by the number of vertical pixels.
For example, a resolution of 1920 x 1080 or 1080p which means full HD, Which means that it has 1920 pixels in width and 1080 pixels in height.
Some of the common video resolutions are :
SD(standard definition) : 720×480 pixels(NTSC), 720×576 pixels(PAL).
HD(Higher definition): 1280×720 pixels(720p), 1920×1080(1080p).
2k : 2048×1080 pixels.
4k : 3840×2160 pixels(ultra HD or UHD), 4096×2160 pixels(cinema 4k).
8k : 7380×4620 pixels.
640 x 480 is now considered a low-quality pixel. Nobody uses it for video anymore, even HD 1280×720 is kind of low quality by today’s standards.
Full HD 1920X 1000 often just be called 1080 or 1080P if you want more robustness then you can move up to Ultra HD often called 4K which is 3840X2160.
Some cameras support resolution between those two, such as 2K which are great quality and you can use them as well. Newer or more expensive can also support much higher resolutions, like 6k,8k, 7680×4320, and even 12k those all are awesome but expensive too.
conclusion
In simple terms, resolution means how many tiny dots called pixels are packed together to create images you see on a screen. More pixels mean sharper images and more detail.
From old school low quality 480p to the ultra detail. 8K the resolution has come a long way. Higher resolutions such as 4K are becoming more common and provide a much better viewing experience. But remember, they also need more powerful screens and devices to work their magic. I also an article an article on frame rate for more information stay connected with me.3
