Pixel size
What's the significance of resolution in video? Everything is measured in pixels.
Pixels represent color information. The thousands or millions of pixels can be combined to produce visual images. As a rule, the greater resolution of the display, the higher the image will appear.
The pixels displayed on the screen is typically described as resolution.
Resolution = (number of pixels within one row) * (number of rows)
Common resolutions for screen resolutions (hence resolutions that are used in video) include:
- SD video quality: 720 x 480
- HD 720 resolution: 1280 x 720
- HD 1080 resolution (full HD resolution size) resolution: 1920x1080
- 4K resolution: 3480 x 2160
Frame rate
Generally, the faster the frame speed is, the smoother the video appears. The two most popular frames include 30fps or 60 FPS. On the lower end, you will see 30 frames each second. This is how fast the human eye can to discern the gaps between frames. The higher the number, it is 60 frames per second. When videos are viewed at 60 frames/second are more likely to look more attractive.
Progression Vs. interlaced scanning
In some instances, resolutions are preceded by letters "p" and "i." While they're not too high, the letters simply show what the picture will look as it's scan.
- "p" is a reference to the progression of " p" is a reference"p" refers"p" is a reference to " progressive," which gives a more accurate picture of each Pixel in the correct way which is what it should be.
