Video bitrate refers to the amount of data that is transferred per second during video playback. Bitrate directly correlates to the quality of your video and the file size; higher bitrates result in higher quality videos, but also larger file sizes. For this reason, it is important to strike a balance between video quality and file size, which can be achieved by optimizing the bitrate.
There are a number of different ways to check the bitrate of a video. One common method is to use a media player such as VLC or QuickTime. These players will typically display the bitrate in the status bar or in the video’s properties.
