Interframe compression for live input streaming reduces the bandwidth required to transmit video data over a network. In interframe compression, each frame is compared to the previous frame. When differences between frames meet criteria defined by parameters set by the user, new frames are transmitted; if the criteria are not met, new frames are not sent and an exact repeat of the last encoded anchor frame is used. WCP and command line operation both support the use of interframe compression.
