The fundamentals of video resolution
Before jumping into the nitty-gritty specifics of SD resolution and HD resolutions, we'll look at some other key components of video resolution such as the dimensions of the pixels, frame rates and "progressive" as opposed to. "interlaced" scan techniques.
Pixel size
What's the resolution of a video? It's all measured in pixels.
Pixels are units used to are used to represent information about color. A large number, if not millions of pixels are combined to produce visually appealing images. In general, the higher quantity of pixels in a screen real estate and the greater resolution of the image will appear.
The amount of pixels displayed on a screen is typically known as resolution..
Resolution = (number of pixels per row) * (number of rows)
Common screen resolutions (hence resolutions used for video) comprise:
- 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
The more frame rates are higher more smooth the video appears. Two common frame rates are 30 frames per second and 60 fps. On the lower threshold, you can get 30 frames per second. It is the rate that a human eye is able to detect the interval between each frame. A higher number is 60 frames per second. When videos are played at 60 FPS, they tend to be more attractive.
The Progressive version differs from. Interlaced scanning
There are occasions when you'll see resolutions, which are which is followed by characters "p" or "i." In the absence of going into detail, these simply represent the way in the way that video is scanned.
- "p" is a reference to "progressive. " "p" is a reference to " progressive," that is an exact representation of the display of every pixel exactly as it is supposed to appear.
- "i" stands for "interlaced. " i" refers to " interlaced," it's a possible way to show every line in an image.
Progressive will look better, but interlaced doesn't appear as sharp however it is better broadcast.
What exactly is SD video?
SD is the abbreviation for standard definition video. It features the aspect ratio of 4:3. Although we've come a long way from the time of 4:3 TV display and broadcast SD remains a valuable option when it comes to the world of streaming live.
SD can be considered as the standard resolution for broadcast and streaming. While you can technically stream with lower resolutions like 144p, 360p or 240p it's unlikely that you'd want to stream lower than SD at the 480p resolution.
Does SD flow quicker than HD?
Both SD and HD are able to stream the same content if you've got a decent internet connection. If your connection to internet is slow, SD may have an advantage. SD needs less bandwidth for streaming and can provide better stream reliability.
But, SD at 480p can provide advantages. Its smaller size implies less bandwidth. This can be helpful when streaming live if you are experiencing less-than-optimal connectivity or upload issues.
Standard definition vs. high-definition streaming
HD streaming video commonly known as HD streaming is higher quality, but it will require higher bandwidth. SD streaming is less quality, but it requires lesser amounts of bandwidth.
What exactly do you mean by HD video?
HD is the abbreviation for high definition. It features the aspect ratio 16:9. In live streaming, HD could mean the aspect ratio between 720 or 1080 pixels.
- "Full HD" is often thought of as 1080p High Definition - also known as 1080 videowhich is the most common term used for high resolution, higher quality streaming and video.
In the event you decide to stream HD videos, make sure to consider the bandwidth of your Internet.
- In order to be capable of streaming in 720p resolution, it's necessary to be able upload at a minimum of 2.5 Mbps.
- To be able to streaming at 1080p it is necessary to have the ability to stream at a minimum of twice the speed.
Do I want to stream 1080p or do I stream in HD 720p?
In most cases it's fine to use the 720p resolution. If you're planning streaming content of higher quality at the highest resolution 1080p will always be better.
What's the differentiator between SD or HD live stream?
Hope you've got gained a better understanding of the SD as vs. HD conversation.
