Lossless compression, on the other hand, eliminates redundant data without affecting quality. However, the compression deletes the extra data permanently, which affects the quality when decoding the file. This method allows you to compress the file to smaller sizes. Lossy compression involves eliminating redundant data permanently. The video codec determines the format of the video.Ĭompression can be lossy or lossless. Redundant data can be, for example, repetitive images or a background that repeats throughout a video.Ĭompression changes the original format of the video into a format supported by the video player. The algorithm search for redundancies, deletes them, thus reducing the size of the file.

The tools that compress the video files are called video codecs.Ĭodec, which stands for “coder-decoder,” is software that applies algorithms to the video. The reduction in size results in lower bandwidth requirements and smaller storage needs. Video compression techniques and tools aim to reduce the size of a video by eliminating redundancies. 🚨 Read Our Latest AI Newsletter🚨 What Is Video Compression?
