BITRATE

‍

Definition:The amount of data bits transferred or processed within a limited amount of time is a bitrate, and video bitrate is the amount of video data transferred in a certain time.

The definition gives an idea of what bitrate or video bitrate is but let us delve deeper into understanding bitrate better.

What is a video bitrate?

A captivating scene turns blurry, often blamed on a weak internet connection, but the real issue is low video bitrate.Video consists of a lot more bits than any high-resolution image. The video may get compressed if the bitrate is too low, resulting in unclear content.

See, the difference here, that’s how bitrate can make or break your video.

‍How is video bitrate measured?

Bitrates are measured in bits per second, or bps, and audio files are measured in kilobits per second, but because video files are large, they are measured in megabits per second, or Mbps.

One common misconception between Mbps (Megabits per second) and MBps (mega bytes per second) is that one capital B changes the whole concept. Mbps denotes the speed of both uploading and downloading, and is also refers as bandwidth whereas MBps indicates the amount of data being transferred.

How bitrate affect video quality?

If you ask the audience, what is the first thing they notice in a video? The most certain answer will be how clear and sharp the video is.

Video quality isn’t limited to resolution and frame rate, it’s the bitrate that save the audience from watching blurry video like …

Bitrate doesn’t just affect the quality but also the bandwidth and storage. Higher bitrate often results in higher bandwidth and storage consumption which can cause issues like buffering or bad start up experience.

While, low bitrate can cause blurry quality and high bitrate can cause buffering, what’s the solution? The solution is simply to find the perfect bitrate which is not too low or too high but a perfect mid, that works according to the need.

What other factors affect video quality?

As we discussed, video bitrate is one of the most crucial parts of video streaming, but what are the other factors that influence video quality?

Frame Rate: A video is a series of still images that, when viewed at a certain speed, give the illusion of motion, and those images are known as frames. The rate at which the images or frames are being played to create the motion is called the frame rate, which is measured in frames per second, or fps. The standard rate for most video formats is 24 fps, but there are also videos with higher frame rates, varying from 30 fps to 60 fps. Frame rate is responsible for how realistic the video looks and at what motion your audience is viewing the video.

Resolution: Video resolution, is used to measure the sharpness and how clear and smooth the video is, the sharpness comes from number of pixel presented, more pixels = sharper video quality.

The video resolutions that are used in videos are 480p, 720p, 1080p, and 4K. The video's resolution, with bitrate and compression, determines the extent of detail your audience will receive.Important point to remember here is, both resolution and bitrate together makes a clear sharp video, messing with either of them can damage the video quality.
