This article includes three parts: What is video resolution? Why change video resolution and how to change video resolution?

What is Video Resolution?

Video resolution is often known as width*height. Simply speaking, video resolution is associated with video quality. High video resolution usually means high video quality while low video resolution means lower video quality. There are three normally used video resolutions: Standard Definition (SD), High Definition (HD) and 4K (UHD).

Why Change Video Resolution?

In short, changing video resolution is to get the video best compatible with your video player, mobile devices and other devices, as the widely used video players, Smart TVs, mobile phones or other video-playing devices support specific video resolution. For example, some models of iPhones can only support to play MPEG-4 video in up to 640*480 resolution; Samsung Smart TVs can only support to play H.264 BP/MP/HP video, HEVC video, Motion JPEG video, VP9 video in 4096*2160 resolution and MVC video, MPEG4 SP/ASP video, MPEG2 video, MPEG1 video in 1920*1080 resolution. So if you have got some higher resolution and want to play it on iPhone or other mobile devices you need to convert your high resolution to low resolution supported by your device or if you have got some video in low resolution and you try to play it on your Samsung Smart TV or other Smart TVs you need to convert your low resolution to the one supported by your TV. But please remember that increasing the video resolution can not always improve the video quality, but the video file size will definitely grow.
