Review on HUIERAV HDMI 2x1 Multi-Viewer Seamless Switch with PIP Function, HDMI 1.3a Full HD 1080P Support, Scaler UP&Down, 4 Picture Mode, RS232 and Remote Control by Elizabeth Morales

Used for live video projection of an organ concert in a church. The organ is above and behind everyone, so we installed a screen so the audience could watch the organ play in front of them. Setup: Two live cameras (tested and working with all these cameras in different combinations Canon 7D, Canon Vixia HXR600, Go Pro Hero 4 Silver) > Black Magic HDMI to SDI Converter > 200ft SDI Run > Black Magic SDI to HDMI Converter > Projector in front of the church. There is a very slight (barely noticable) delay, but it's close enough to real time that it shouldn't disturb anyone in the audience - the speech to the camera was very much in sync. Switching was indeed smooth at most resolutions, but not at 1080p, where I could get blue flickering between switches (this could be due to another issue in my signal chain, likely not the switch). The remote control was helpful.
