Security is the main concern in addition to fast communication in video transmission over the network. Video encryption becomes the requirement of the day because they want to prevent unauthorized access to the private videos. Video conferencing is to be made secure by the use of cryptographic techniques and encryption algorithm for video transmission. This paper contains brief description of certain video encryption algorithms which were proposed in the surveyed papers. Any algorithm can be selected on the basis of its efficiency in terms of security and application in use.
