These files can then be accessed from a WWW server or downloaded and played back later. This technology may have use with a music class to make listening examples available or for other classes to provide demonstrations. Video and audio files can be quite large and thus have long download times. Class members must also have sufficient computer resources to retrieve and play these files. Audio files can be recorded with any computer equipped with a sound card.
Video recording requires a special piece of hardware known as a video capture card.
Input to this capture card can be a camcorder, VCR, or other video source. When dealing with video and audio recordings, copyright issues must be addressed. If the material is of your own creation, you may use it as you wish. If the material belongs to someone else, the question of copyrights comes into play. Often your library can provide information on this subject.
