The foundational principles of resolution for video
Before getting into the particulars of SD resolution, as well as HD resolutions, we'll look at the major elements of resolution in video which include the amount of the pixels and frame rate and "progressive" instead of. "interlaced" scanning methods.
Pixel size
What's the resolution of video? All it is in the pixel.
Pixels are units which depict colors. Millions of pixels can be combined to make images. More of the screen's real estate is filled with pixels, which is why more detailed images will be displayed.
The amount of pixels display screens are usually known as resolution.
Resolution = (number of pixels per row) (number of rows) * (number of rows)
Screen resolutions that are common to screens (hence the term "video resolution) consist of:
- SD video quality: 720 x 480
- HD 720 resolution: 1280 x 720
- HD 1080 resolution (full HD resolution size) Resolution: 1920 x 1080
- 4K resolution: 3480 x 2160
Frame rate
The higher the frame rate the more fluid and smooth the film appears. Two of the most viewed frames include 30 frames per second, or 60 frames per second. On the lower scale, there are 30 frames in a second, which is the rate at which a human eye detects the gap between frames. On the upper end of the scale is sixty frames per second. If videos are running at 60 FPS the videos will usually appear better.
The Progressive technology is distinct from. interlaced scanning
In some instances, you may see resolutions followed by an alphabet "p" or "i." Without getting into the details, it's just a way that video is processed.
- "p" is a reference to "progressive. " p" is a sign of " progressive," that is a superior description of the dimensions of each pixel the way it ought to be.
- "i" is an abbreviation that means "interlaced. " "i" stands for " interlaced," that is a different method that uses shortcuts to show each line in an image.
Progressive can be more attractive but interlaced may not have the same clarity, even though it could be broadcasting faster.
