Digital video is that video that is recorded (encoded) onto a computer hard drive into some proprietary format such as AVI, MPEG, Quicktime, Windows Media, Real Video, or some derivative of the above list. Similarly, audio is encoded into formats such as .wav files, .aif files, or now the very popular MP3 files. To encode the media in real-time onto a computer requires a computer that is made capable with a video and or audio input card. Some video clips can be converted from one format to another via software encoding programs. MPEG and Real clips cannot (and are not recommended to be) encoded into another format. Often, but not always, the process of encoding is designed to compress a video or audio clip into a smaller size. This is not desirable when the video is being encoded for editing in a non-linear editing system such as Media 100.
