Review Summary
2020-08-26T12:34:41
The Roland V-1SDI has been at work in our church video workflow for a few months now. For the most part, it is a really nice little switcher. It does insert an annoying digital audio noise, and the RCA audio jacks are not the best line input for high-quality audio coming out of our Behringer X32 board. We have since bypassed the Roland for audio input directly into the capture card. There are some function limitations that more expensive switchers allow. But if you have 2-3 cameras and a computer graphics input that need "semi-professional" output for streaming or recording, this is a nice entry-level switcher. The included "non-branded" capture card failed after 3-4 weeks. We got a nice Magewell card that works great so far.

V-1SDI 3G-SDI Video Switcher
Professional SDI Video Switching that you can take anywhere
V-1SDI is a flexible and versatile video switcher that makes it easy to connect and switch professional 3G SDI cameras and playback sources along with HDMI sources including cameras, smart phones, computers, tablets, Blu-ray players. Compact and portable, the V-1SDI delivers professional switching results with its easy to use hardware interface complete with T-Fader and easy-to-see backlit buttons.
With support for 3G-SDI, the V-1SDI can operate at full 1080p resolution and can take advantage of the longer cable distance of SDI making this compact solution suitable for events and applications in even large spaces with the most professional level of SDI camera sources.
Inputs and Outputs
Inputs
The V-1SDI has two dedicated 3G SDI inputs, a third channel input that supports 3G SDI or HDMI and a fourth channel HDMI input that also includes scaling. This makes the V-1SDI ideal in a variety of configurations for both an all camera applications and applications that mix cameras, video sources and computer data sources.
Outputs
The V-1SDI has two 3G SDI Outputs 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.
Quad Input Multi-viewer
The four-way multi-view preview screen shows all four input sources on a single display for confident monitoring. A red border shows the video currently being output and a green one indicates the video to be output next. It also includes audio metering for all input sources and the main output.
Composition Effects
The V-1SDI includes DSK (Downstream Keying), Picture-in-Picture (PinP), Split and Quad composting effects ideal for creating news style broadcasts and corporate presentation content. The DSK function is great for overlaying titles, song lyrics or logos onto incoming video sources that can be switched in the background while text or images remain displayed. The DSK supports both Luminance Keying (Black / White) and Chroma Keying (Blue / Green).
Audio Mixing
Included is a 14 channel digital audio mixer. The V-1SDI can mix 5 stereo audio inputs from the SDI or HDMI ports, the stereo line level input and a mic level input. Every audio input is equipped with a DELAY function to synchronize the video and the audio as well as EQ for adjustment of sound quality. Audio output is equipped with a MASTERING function to improve the sound of the final audio mix. Audio follow function enables the audio to transition along with the video.
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.
Remote Control
Remote control is possible with the V-1SDI RCS dedicated computer software for Mac and PC connected via a USB cable. The application offers a detailed view of the connected V-1SDI and can be used to switch video, mix audio or change settings. V-1SDI RCS Ver.1.5 supports sending a Still Image to the V-1SDI. The STILL IMAGE EDITOR allows both images and text to be edited making it ideal for easy, on-demand creation of subtitles and graphics. For integration with A/V control systems, the V-1SDI is equipped with a serial connection for control by industry standard RS-232 serial controls.
