Roland V-4EX overview

  • 1Description

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.

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. The V-4EX features an an output scaler that can scale your video to 1080p or 1920 x 1200 via the HDMI/RGB output. The program feed is available for streaming or capturing to a computer via the USB Type B port on the unit.

Video Input/Output
Inputs 1 to 3 feature composite (BNC) or HDMI while input four accepts HDMI, RGB/Component or S-video. Input 4 can accept 1080p input signals via the HDMI connector. Program output is available via the composite (BNC), HDMI or RGB/Component 15 -pin connector. HDMI output is scaled up to 1080p, and 1920 x 1200 is available through the 15-pin connector. Additionally you can stream the program output for the web through the USB port.
High Quality Digital Signal Processing
The V-4EX processes input video signals at SD resolution using 8-bit progressive internal processing with a color sampling rate of 4:2:2 (Y/Pb/Pr). The mixer also features audio resolution of 24-bit/48 KHz.
Frame Synchronized Inputs
Featuring one frame synchronizer per input, the V-4EX allows you to input video from non gen-locked sources and still seamlessly switch between them.
Digital Effects
The V-4EX features a selection of 148 digital effects including colorize, strobe, mirror, multi-screen, negative, shake, afterimage and silhouette. It also features composition effects such as picture-in-picture, chroma key, and luminance key. A single button press can recall the effects, and you can modify select effects using the panel mounted control dial.
259 transitions (wipes) are available to you to switch video from input A to input B.
The built-in multiviewer can display all active inputs on the same screen on the V-4EX. You can select input sources by simply touching the image you want to select on the built-in screen.
Memory Function
The built-in memory function allows the memorization and convenient recall of panel settings, such as effect assignment to each button. The memory stores up to seven configurations and keeps stored settings even with the power off.
Preview Function and On-Screen Menu
The preview function allows monitoring of each of the four input sources or the output source, or the output can be overlaid on top of the four input sources on the built-in multiview monitor. Major functions can be viewed on preview screen using the convenient on-screen menu.
Synchronization with MIDI Equipment
The V-4EX supports remote control by MIDI or USB, and can be operated remotely from an external device that supports MIDI Visual Control.
Auto Switching to Musical Rhythm
Use this feature when you want to perform switching on the rhythm of background music. By default, switching is performed at 120 BPM (beats per minute).
The V-4EX is HDCP compliant, although you have to enable HDCP using the menu system.

    Roland V-4EX reviews

    V-4EX Four Channel Digital Video Mixer with Effects is rated 4.5 out of 5 by 15.
    Rated 5 out of 5 by from Wonderful Upgrade This mixer was everything I was hoping it would be plus more. If you're familiar with the V4, then this will be an easy and awesome upgrade experience for you. I was using the V4 for a weekly live event. We finally had the budget to get some upgrades and go HD (but not a huge budget) so this V-4EX fit perfectly. It was at a very surprisingly wonderful price. This board was so easy to use that, I brought it to my church and hooked it up about an hour before service and the person who had to operate it (a non techie volunteer) was able to use it without any training! I really appreciate the onboard touch screen and the intuitive controls. This was a great buy, and makes my life instantly easier.

    Rated 4 out of 5 by from Product delivers right out of the box This product is used in a church environment with 3 Sony HandyCams via HDMI, a PC via HDMI and then using the USB out to a Mac to stream and the HDMI out to the Matrox Monarch box for recording. This device is able to be used in about 20 minutes with minor tweaking to get started. Once the complete set up was tested and used another hour really fine tuning the sync of audio to video. Now this machine is being operated by some very astute kids that are 10 years old. Switching screens, using the touch screen and start up is great. 2 reason though why I didn't give this a 5 star. The device has no headphone out jack to monitor the audio level and the menu for choosing the audio on/off and levels is a little confusing. The instruction manual is fairly well written but to a novice like myself it didn't explain everything.

    Rated 5 out of 5 by from Brings my webcasts to a whole new level I've been producing corporate webcasts for several years using a single camera set-up. Ordered this at the suggestion of a friend in the business and I am thrilled with the quality, ease of use, and level of professionalism it brought to the game. Within 24 hours of receiving the switcher I was broadcasting a 3-camera, 2 speaker webcast with live graphics to a large international audience. Great tool to have. Packaging was excellent. Be sure you have all the cables you need as it comes with only the power cord.

    Rated 5 out of 5 by from Excellent mixer I run a live video broadcast through the internet and this mixer plugs right into the computer where I use Adobe Live encoder. However, I don't use the audio part of the mixer because it doesn't have an optical connector and I like to keep things digital. It's not full HD (it's 720p) but the video quality is decent for internet use and regular DVD's. Overall I'm more than satisfied with the performance.
    Date published: 2013-05-01
    Rated 2 out of 5 by from Not High-Definition Looks like a good product, new model, modern features, touchscreen interface, has HDMI (High-Definition Multimedia Interface) ports so I assumed it was an HD mixer. It was not. Only one port is HD the other three are SD. I had to send it back. This needs to made more prominent on the page.
    Date published: 2016-10-24
    Rated 4 out of 5 by from Easy to use We use our Roland V-4 Mixer at our church. The one thing that concerned us was we don't have tech resource people. What pleases us most is the simplicity of installing the mixer and using it. We find that non-tech people can run the mixer and do a great job. We have teens and retirees running the mixer and it has performed excellently. We are a small group and we connect to another small group over the internet using this mixer.
    Date published: 2013-09-11
    Rated 5 out of 5 by from Excellent Mixer for Web and Live Events We purchased this mixer for live event production and web streaming and it's proven to be a great tool for both. The setup and operation were both very intuitive. I highly recommend this mixer.
    Date published: 2013-06-13
    Rated 4 out of 5 by from Great entry Level switcher I use this several time a week with my high school Video Production Students to broadcast sports, award shows and other events. I wish the preview monitors were nimbered, just would make it easier for them. I haven't had any issues with it's functionality except when I attempt to rum my signal through our Ikan VH8 doesn't sync. direct for our Panasonic HMC-150 and HMC-80 cameras work flawlessly. not sure if its an Issue with the Ikans...
