In addition to a number of powerful video effects, the user interface incorporates dial controls for effects on each bus and master output dial.  The innovative design incorporates a video switcher, audio embedding, preview monitor and streaming-ready USB output all in a single unit.  Inputs one to three feature composite (BNC) or HDMI while input four accepts HDMI, RGB/Component or S-video.  The output features scaled-up HDMI, RGB/component, or SD composite with an additional HDMI output for external preview monitor.  The Roland V-4EX features a stereo RCA audio input allowing you to embed audio into the HDMI outputs and USB stream, which are especially useful for web streaming and recording applications.  As a USB Video/Audio class device, web streaming is effortless by simply connecting to a computer running a live streaming service.  You can also record the output using Roland's free Video Capture for Windows software or by using Quicktime on a Mac.

Designed to be a live production switcher and web streaming device, the Roland V-4EX features audio embedding, built-in audio mixer with up to 4 frames delay to "lipsync" your video source.  It supports HDCP video allowing you to mix copyright protected material such as game consoles and Blu-ray content in your live production.  HDMI inputs one to three accept video resolutions up to 480p/576p and HDMI input four accepts resolutions up to 1080p and RGB up to WUXGA (1920x1200).  Although internal processing is SD-based, the output can be scaled up to 1080p or 1920x1200.
