The Roland VR-3EX SD/HD A/V Mixer with USB Streaming is a live production switcher and web streaming device featuring 3 x SD HDMI/composite inputs, and an HD HDMI/component or SD composite input. The unit processes the video internally using progressive processing at SD resolution. This means the VR-3EX does not introduce interlace artifacts, which results in a cleaner output than with regular SD switchers. Four built-in frame synchronizers, one per input, allow you to support and cleanly switch input video from sources that are not gen-locked. Plus, the fourth input features a built-in scaler that allows you to work with HD resolution video. It features a scaler on the output, allowing you to upscale to HD if you require, and the built-in USB port allows you to simultaneously record your program to a Mac or PC or upload to various streaming services. This unit is well-suited for clubs, concerts, Houses of Worship, events, weddings, education, and sporting events.

The VR-3EX features a built-in Keyer for luma, chroma, and PIP keying effects. It also includes 250 transition and 11 built-in effect types. The built-in 18-channel audio mixer accepts audio embedded in the HDMI stream, the 4 x balanced XLR inputs, unbalanced analog sources via the two RCA jacks, stereo mini jacks, and the built-in microphones. You can also delay the audio by up to 4 frames to adjust the "lip" of your video. The built-in multiview screen can show your four inputs on the screen at the same time and you can transition from one camera to the next by merely touching the camera view on the monitor screen.
