$125 Roland V-1HD+ Video Switcher Kit
Roland's V-1HD+ Compact 4 x HDMI Video Switcher is a portable solution for HD video production that accommodates up to four HDMI inputs, as well as PC resolutions over one of the inputs. Each input has a frame buffer/TBC and support frame rate conversion, so you don't need to genlock your input sources together. You can control the switcher manually by using the built-in controls or remotely via RS-232, and it has a tally output for working with live cameras. Select your working resolution and switch between four input sources. Built into the switcher is a 14-channel audio mixer that can de-embed and embed audio signals from HDMI.
