Inputs. Three 3G-SDI inputs and two HDMI inputs… that would make this a 5-Channel switcher, right? The V-1SDI is a 4-Channel video switcher with two dedicated 3G-SDI inputs and one dedicated HDMI input; the fourth input source supports either.

Outputs. This unit outputs two 3G-SDI, and one HDMI output. SDI PVW and MULTI-VIEW outputs are assignable from Program, Multi-view Preview or Full Frame Preview for flexibility in different applications where output display devices support either SDI or HDMI inputs.

Multi-Viewer. Roland’s V-1SDI holds a quad input multi-viewer whose preview screen shows off all input sources on a single display with source labelling. Along with "live" and "preview" borders, this video switcher also includes audio metering.

Composition Effects. Popular composition effects including an Downstream Keyer (DSK) and Picture-in-Picture (PinP) come standard on this Roland video switcher. Both Luminance Keying and Chroma Keying are supported.

Audio Mixing. The digital audio mixer of the V-1SDI has 14 channels and can mix five stereo audio inputs from the SDI or HDMI ports, the stereo level line in, and a mic level in. Each audio input is equipped with a delay function (which maxes at 500ms), and audio OUT is equipped with a mastering function for adjusting the final mix. This unit’s audio follow function pairs the audio with its source video for transition matching. The final audio mix is both embedded in the SDI and HDMI output along with the video signal and is also output to the stereo audio output jacks for sending the audio mix to a PA system or recording it on an external device.
