Resolution is used to represent the number of pixels in a frame or picture of a video. For example, 2MP, 1920x1080, 1080P.
The higher the number of pixels (resolution), the more detail the resulting image can display. Correspondingly, more processing power and storage space are needed.
Common resolutions as below:
320x240 | ||
| 640x480 | 0.3MP | |
| 800x600 | 0.48MP | |
| 1280x720 | 1MP | 720P |
| 1280x960 | 1.3MP | 960P |
| 1920x1080 | 2MP | 1080P |
| 2048x1520 | 3MP | |
| 2592x1520 | 4MP | |
| 2592x1920 | 5MP | |
| 3840x2160 | 8MP | |
