Video resolution is the quality in which video can be displayed and is described in lines of pixels e.g. 1920 x 1080 . NTSC video frame is 720 pixels x 486 lines, and a PAL video frame is 720 pixels x 576 lines. HD video with 1080 lines uses 1920 horizontal pixels per line (1920 x 1080). HD video with 720 lines uses 1280 pixels per line (1280 x 720).

Both of these formats have an aspect ratio of 16:9. PAL NTSC was a 4:3 aspect ratio which suited the monitors and TVs at the time . Today 16:9 is the most common aspect ratio for modern monitors and TVs.

Currently the main resolutions required are SD, HD, UHD and 4K – however there are multiple types of resolutions which fall in-between / higher and lower than the scales shown and different aspect ratios.

In addition to resolution there is also video frame rate to consider . Frame rate (expressed in frames per second or fps) is the frequency (rate) at which consecutive images called frames appear on a display. In the older PAL NTSC standard the frame was broken down into two fields which added together created a frame. PAL would use 50 fields per second or 25 frames per second. This was called Interlaced video. Today most video consists of frames only which is called Progressive video and suits modern LCD displays.
