What is the Bitrate of a Video and what is it useful for?

Bitrate is the property that determines the amount of data that is processed per second in a video. The bitrate determines the quality and size of a video, a video with a very low bitrate can be blurred and with very little clarity, but less heavy, however, a video with a high bitrate can be seen with higher quality but heavier.

When you are using a program to prepare or render videos such as Sony Vegas, Camtasia Studio, OBS, ect, you have the possibility to choose how many bitrates you want to record or render the video.

The higher the bitrates in rendering the more consumption this will make to the processor of the computer, the longer it will take to finish and the heavier and sharper the video. The value of bitrates is represented in Kbps or Mbps.

Know the bitrates of a video

To know the bitrates of a video you only need to right click on it and then click on “Properties“. Then you go to the “Details” tab and there you will see the specifications of the video, among them the bitrates of the video.

The following example shows two images. The first one is a video rendered at 30,000 bitrates. The second image is taken from the same video, but this time it was rendered at 3,000 bitrates.


Notice the difference in quality?

You can also realise this in Youtube videos and when you reduce the resolution to a video not only reduces that, but also your bitrates, making the videos are seen with less quality so that they weigh less and load much faster.

The quality of Youtube videos

Youtube videos with their resolutions represent the following quality:

Kind Bit Rate, Standard Image Frequency
(24, 25, 30)
Bit Rate, High Image Frequency
(48, 50, 60)
2160p (4k) 35-45 Mbps 53-68 Mbps
1440p (2k) 16 Mbps 24 Mbps
1080p 8 Mbps 12 Mbps
720p 5 Mbps 7.5 Mbps
480p 2.5 Mbps 4 Mbps
360p 1 Mbps 1.5 Mbps
