Roland V-1HD 4-channel HD Video Switcher

The Roland V-1HD 4-channel HD Video Switcher is a portable, standalone HD video mixer built for live events, houses of worship, and multi-camera streaming setups that need clean, professional switching without a dedicated control room. It lets a single operator connect and switch between video cameras, action cameras, smartphones, computers, tablets, Blu-ray players, and other HDMI video sources with a simple push of a button or slide of the T-fader.

The switcher accepts 4 HDMI type A video inputs, supporting 1080p, 1080i, and 720p resolutions at 50/59.94Hz, with both progressive and interlaced signals usable simultaneously (interlaced input is converted to progressive internally). Each input incorporates its own frame buffer/TBC, eliminating the need to genlock input sources together, so non-genlocked cameras and play-out devices can be mixed freely. Video is processed at 4:2:2 (Y/Pb/Pr), 8-bit. Two HDMI outputs provide program and preview (multiview) feeds, and output is selectable between 1080p, 1080i, and 720p formats.

Transition effects include standard Cut, four Mix transitions (Dissolve/FAM/NAM/Mosaic), 30 Wipe types, and 11 Transformer effects for instant switching or creative visual transitions. Additional video effects include Negative, Emboss, Colorize, Colorpass, Posterize, Silhouette, Monocolor, Find Edge, Flip, luma key (white/black) and chroma key (green/blue), along with picture-in-picture (quarter and half-screen) and split-screen composites. Other functions include 8-type Memory presets, a Freeze function to pause incoming video, BPM Sync for auto-transitions synchronized to a song’s tempo, Input Scan for automatic sequential switching (1-120 second intervals), and Output Fade to white, black, or audio.

A built-in 12-channel digital audio mixer processes audio at 24-bit/48kHz, with inputs including a stereo L/R RCA pair, a 3.5mm stereo mic jack (plug-in power supported), and HDMI-embedded audio from each video source; outputs include a stereo L/R RCA pair and a 3.5mm stereo mini-jack, along with headphone monitoring. Each channel includes an adjustable audio delay (up to 500ms) to help synchronize video and audio, along with an audio-follow-video function.

Handling centers on large, backlit, color-coded buttons for intuitive switching even in low light, with a red-lit button indicating the current program source and a green-lit button showing the next source queued for output. The unit can also be remotely controlled via USB or MIDI, or through Roland’s V-1HD RCS software control application for Mac, PC, and iPad.

Build quality centers on a compact, portable chassis measuring approximately 12.33 x 4 x 2.33 in. (31.3 x 10.2 x 5.9cm) and weighing approximately 2.6 lb (1.2kg), drawing approximately 1.5A current and 18W of power consumption.
