DVSwitch
DVswitch is a digital video mixer intended for interactive live mixing of several incoming DV video streams. It was originally designed for the needs of DebConf; It has now been used for various other conferences, meetings and live musical performances. Currently DVswitch can combine audio from one source with video from another; combine two video streams with a picture-in-picture effect, and cross-fade for a configurable amount of time between sources. It works solely with the DV format since it is widely supported by camcorders and it allows for low latency display and cutting.
