The problem with video files is that they can become huge, especially when saving in high quality. To address this issue, developers created programs called codecs. The job of codecs is to encode and compress large video files to make them easier to store and share. Then, when it's time to open a video, the codec decodes the data so that you can view or edit it.T here are several codecs for video compression, but the most common now is H.264 or AVC. Your chosen file extension is a container or wrapper for codecs.
