Video Compression

What Does Video Compression Mean?

Video compression is the process of encoding a video file in such a way that it consumes less space than the original file and is easier to transmit over the network/Internet.


It is a type of compression technique that reduces the size of video file formats by eliminating redundant and non-functional data from the original video file.

Techopedia Explains Video Compression

Video compression is achieved using a video codec, which employs one or more algorithms to reduce file size. This process typically involves eliminating redundant elements such as repeated images, sounds, and scenes. For instance, if a video frequently reuses the same background or sound, or if it contains superfluous data, these elements are removed to decrease the file size.

Following compression, the video’s format is altered to a new one, based on the codec used. To play the compressed video, the video player must either support this new format or integrate with the codec.

Moreover, after compression, users can enhance their viewing experience and access major streaming platforms more effectively by using VPN services tailored for online streaming.
