It can store video data, audio data, video codec, audio codec, and metadata for further identification and detailing of those data streams. These formats can also be referred to as an extension because they are often seen as file names like AVI, MOV or MP4 etc.
After the video file is compressed, the container format holds all the components together and delivers the final set for playback.
