Roland V4EX Video Mixer
The Roland V-4EX Four Channel Digital Video Mixer with Effects is a live production switcher and web streaming device that improves on the Roland V-4 Video Mixer by adding a built-in multiviewer with touch control screen and HDMI in/out, with 1080p/RGB WUXGA (1920 x 1200) support on one input, and 1080p output. You can switch between four video sources and deliver via HDMI, RGB Component, composite video and stream via the built-in USB port. Four built-in frame synchronizers, one per input, allow you to support and cleanly switch input video from sources that are not gen-locked. This unit is well-suited for clubs, concerts, worship, events, weddings, education and sporting events.
The V-4EX features a built in Keyer for Luma, Chroma and PIP keying effects, including the 259 transition and 148 built-in effects. The switcher features a familiar analog T-bar transition controller with a choice of three transition curves and the T-bar itself can be rotated for user comfort without affecting its operation. The built-in audio mixer accepts audio embedded in the HDMI stream, or from an unbalanced analog source via the two RCA jacks, and embeds the mixed audio in the HDMI output stream. You can also delay the audio by up to 4 frames to adjust the “lip sync” of your video.
