Review: Roland VR-1HD AV Streaming Mixer, Part 1: Basic Hardware Functionality

In Part 1 of this 2-part review, Jan Ozer examines the essential hardware functionality, features, and usability of the Roland VR-1HD AV Streaming Mixer.

Roland’s VR-1HD ($1,495) is an inexpensive video mixing appliance that’s an alternative to software-based mixers like Wirecast or vMix. In this two-part series, we’ll look first at the basic hardware mixing capabilities of the VR-1HD, and then look at some advanced audio mixing capabilities, and features available when you connect the VR-1HD to a computer, including recording, streaming and some additional mixing functions.

As an overview, the VR-1HD mixes audio and video from multiple sources and sends a configurable webcam-like USB stream to a computer to push to a live streaming service. The unit has features appropriate for a broad base of users, including gamers and musicians, though my focus will be on more prosaic interviews and webinar-type productions.

Video I/O

The unit has three video inputs, all HDMI. Input 3 is a no-latency input with a passthrough to an HDMI output, so if you’re a gamer you can route your monitor output through the board with zero delay. Besides the Through output, there’s a Main output which displays the live audio and video feed and a Monitor input you use to control the menu options and configure the outputs. You can probably live without the Main output if you’re space-constrained, but you should set it up the first few times you run the unit to get familiar with what it does and how it works.

You can input audio from any of the HDMI sources. Besides that, there are two XLR/1/4" combo jacks with phantom power and a line input via RCA connectors. Plus, the unit can accept audio via USB input from a computer.

The onboard mixer contains volume controls for the two mics and line input, but not for audio coming in with the HDMI signals or USB, though you can set levels for these via menu commands. You can listen in via a headphone jack, and send audio out to any monitor, plus line out via two RCA jacks, plus audio with the live USB feed.

Basic Video Switching

Figure 1 (below) shows the switching surface with the three video inputs on the bottom right. When running, the buttons for all live feeds are lit; red if the feed is currently live, white if available but not live. As you would expect, you switch through the feeds by clicking each button.

To the left of the three inputs is the Auto-switch button, which lets you select one of the four auto-switch options discussed in the second segment of this review. As with all configurable options, you choose and configure your options via the Setup box in the middle top, where the Menu button opens the menu and the Value knob lets you move through and select your options.

Above the video inputs is the Scene section, which lets you combine inputs via picture-in-picture or horizontal or vertical screen splits as shown below buttons A-E. The unit comes configured with the combinations shown below the buttons which you can customize to your liking by clicking the Scene Edit button and using the Value knob from the Setup section.

Configuring the Scene Settings

My basic configuration was two input cameras and a PowerPoint presentation coming in from a computer. Though I didn’t need to configure any of the inputs, the VR-1HD can zoom, scale, position, and adjust the brightness, contrast, or color values of any input.

To combine the inputs into the picture-in-picture shown in Figure 2 (below), you work with the buttons in the Scene box in the middle right of the switching surface (Figure 1). Click the button to configure (I used Button A for Figure 2) and then Scene Edit, which exposes controls that you work through using the Value knob at the top of the unit. Here you choose the background and foreground videos and can adjust the size, aspect ratio, cropping, zoom ratio, and position of the smaller window.

Figure 2. The Roland makes it easy to configure picture-in-picture shots like this one, with PowerPoint coming in via HDMI from a computer and the video coming in from a camera.

I configured Button A for the picture-in-picture shown in Figure 2 and Button C for a side-by-side shot of the two video feeds. During the production, the configured Scene buttons act like individual inputs that you switch to by pressing them, as you do with the three input buttons on the bottom right. So, if the host is input 1, the guest input 2, and a side-by-side combination that you’ve configured as input C, you would manually switch between the three shots by pressing input 1, input 2, or scene C, which transitions into the selected shot or scene. Very simple and very easy for a producer/performer to manage.

However, transitions were downright funky. For example, when switching to a composited video, the two videos comprising the composited shot never appeared simultaneously. So, if you transition from a single shot to a side-by-side composite, the videos in the side-by-side video appear at slightly different times. You can minimize this by shortening the transition time but you can’t eliminate it; even with a zero transition time, one video in the composited shot will appear before the other.

In addition, you have three transition options, either a mix fade (dissolve) or black fade (fade to and from black), or a cut if you set the transition time to zero. But only transitions to, from, and between composited scenes can be black fades; all others are mix fades or cuts. So, if you choose the black fade transition, when you switch from a camera input to a scene or scene to scene, you’ll get a black fade, but if you switch directly to and from camera inputs, you’ll get a dissolve or cut. You can configure a Scene to mimic a camera input and avoid this issue, but then you lose up to three scenes. Not a show stopper, but a bit unusual.
