The foundations of resolution for video
Before getting into the nitty gritty of SD resolution and HD resolution, we'll review several other important elements of resolution in video: the amount of pixels used frames per second, frame rate as well as "progressive" when compared with. "interlaced" scan techniques.
Pixel size
What is the meaning of resolution in video? All of it is measured in pixels.
Pixels represent color information. Many thousands, or even millions of pixels combine to create visual images. In general, the higher resolution of pixels in the display, the higher the quality of the picture will appear.
The amount of pixels visible on the screen are usually expressed as the resolution.
Resolution = (number of pixels within one row) * (number of rows)
Common resolutions for screens (hence resolutions used for video) are:
- 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, the more smooth the video will appear. The two most common frames include 30fps or 60 fps. On the lower end, you will see thirty frames per second. This is the speed that the human eye is able to detect the gap between frames. A higher number is 60 frames per second. Videos viewed at 60 frames per second are likely to look more attractive.
Progression Vs. interlaced scanning
In some instances, there is resolutions that are preceded by letters "p" or "i." Although they aren't too deep the letters simply show what the video will look like when it is scanned.
- "p" is a reference to progressive " p" is a reference"p" is a reference to " progressive," that provides an better representation of the image of every Pixel in the correct way that it ought to be.
- "i" is the short word that means "interlaced. " "i" is a reference to " interlaced," that is a different method of using shortcuts to show every other line in an image.
The look of progressive is better while interlaced may not be as clear, but it can be easier to transmit.
What is SD video?
SD stands for standard definition video. It has an aspect ratio of 4:3. While we've made progress from the time of 4:3 television display and broadcast the SD format is still suitable for streaming live.
SD can be called the standard resolution for streaming and broadcasting. Though you could stream at lower resolutions, such as 144p, 240p, and 360p, you probably won't want to dip lower than SD at 480p.
Is SD run more quickly than HD?
Both SD and HD will stream similarly provided you've got a reliable internet connection. If the connection you're able to use isn't as fast, SD may have an advantage. SD needs lesser bandwidth to stream and provide the most stable stream experience.

What does it mean? HD video?
HD stands for high definition. HD is distinguished by the aspect ratio 16:9. Live streaming is possible. HD can be a reference to the aspect ratio 1080 or 720 pixels.
- "Full HD" is often thought of as 1080p HD, also known as 1080 videoit is also often used to create high-resolution and higher-quality video and streams.
