Roland's V-1HD 4 x HDMI Input Switcher is a portable solution for HD video production that accommodates up to four HD inputs. The inputs each have a frame buffer/TBC so that you don't need to Genlock your input sources together. You can control the switcher manually by using the built-in controls or connect it to a computer or iPad running optional software for electronic control. Select your working resolution and switch between your four input sources. Built into the switcher is a 12-channel audio mixer, which can de-embed and embed audio signals from HDMI. The integrated T-fader allows you to manually control the speed of transitions, or you can use the take button to actuate your selected transition. The unit features a program and multi-view preview output as well as an analog audio input and output. Though small in size, it allows you to perform picture-in-picture, green-screen, and other keying effects, and a transform control enables advanced video effects on your footage.
