This codec plays nicely with mobile devices of every manufacturer. For best use by streaming services, use the H.264 codec. Codecs related to a standard called MPEG-4 are very common. This process of encoding or decoding a compressed video file uses software (or hardware) called a codec. mp4 format even if you are using a Mac.Īs the video is being rendered, it is then encoded into a format that saves file space and is viewable by a video player, either as a file loaded into the player, or streamed from a service.
