Intuitive video mixing for incredible performance.

The NuVJ allows DJs to incorporate images and video clips in much the same way as mixing music. With the NuVJ, the VJ can trigger images and video clips, add effects to them, mix them through an onboard DJ style crossfader and tweak them in order to create unique and spectacular shows. The hardware controller works seamlessly with existing DJ gear and the software is compatible with most computers and laptops.

The NuVJ integrates tightly with the accompanying Arkaos custom software and is designed to work intuitively in the same way that DJs mix music. The software package includes a library of video clips and over 30 real-time video effects. The NuVJ is simply easier, more versatiile and more affordable than any other VJ product on the market.


This page contains a new software update that brings substantial new functionality and improvements to NuVJ free of charge for registered NuVJ users.

Arkaos v1.50 software for NuVJ adds a new, multi-threaded engine along with a new internal codec for optimal decompression of several video formats including QuickTime Photo-JPEG, DV, MPEG. With this new update users can now deinterlace video clips with a right click option.  New loop editing functionality, enables users to edit the loop length of their clips and movies on the fly.

A new Flash player has been added with audio-reactive Flash animation support and input gain control, which is useful for generators, audio-reactive flash and BPM detection. Input gain controls make beat synchronization easier than ever.

The upgrade also features advanced luminance/chrominance keying controls, 11 new effects and a new visuals panel that displays the movie player involved, the codec, the resolution. Mac users can also achieve high-resolution input support, improved DV camera quality, and the ability to play multiple DV cameras at the same time.

  • How many cameras can I use with NuVJ?
    • NuVJ supports as many cameras as your computer can support, through USB, PCI acquisition boards or FireWire input (DV cams). Under Windows, make sure your device has a DirectShow compatible driver or it won't be recognized by NuVJ. On a Mac, your camera must be supported by QuickTime.
  • How can I play DVD content in NuVJ?
    • You must first rip the DVD's content to a video file on your computer. There are many utilities that can do this very simply on Mac and on PC. Try to convert the DVD in small sections and use QuickTime PhotoJPEG compression if possible.
  • What is the maximum resolution supported by NuVJ?
    • NuVJ is only limited by your computer's hardware capabilities. On a powerful computer, even very high resolution files (1920x1080) will work perfectly.
  • What is the maximum output resolution of the final mix?
    • NuVJ's final mix resolution is only limited by your computer's video card and the display device connected to it (monitor, TV, projector, etc) If you are using a computer's S-Video output, your resolution is limited to 640x480 for NTSC standard (US) or 720x576 for PAL standard (Europe).
  • Does NuVJ support audio within video files?
    • NuVJ will only play the audio from a video file when using QuickTime .mov files. You must also enable it in the NuVJ software's Preferences dialog.
  • How can I improve the scratching of video files on my computer?
    • Scratching efficiency depends on the way video files are encoded. For optimal performance, recompress your files into QuickTime PhotoJPEG format. If you choose another format/codec, the most important thing is to have one key frame per frame (all frames are key frames). You can do it with QuickTime Pro, Sony Vegas, Adobe Premiere, Final Cut, etc.
  • How do I make sure that my downloaded video content will play correctly?
    • Make sure the encoding format is supported by NuVJ on your platform. NuVJ supports almost all formats. Using Windows, any movie playing in Windows Media Player or QuickTime Player should work. Using a Mac, if QuickTime can read it, NuVJ should as well. In Windows, make sure the applicable codecs for your video files are installed. AVI is just a file format and can contain various types of compression, each with its own codec such as: DivX, XVID, M-JPEG, Cinepak, Sorenson, etc. Always try to use official codecs. On Windows, QuickTime is not installed by default, make sure you installed QuickTime if you want to play QuickTime (.mov) files. Note also that most files on the internet are encoded in a format that is very poor and not at all suited to be manipulated. See further answer and the Optimization section of this document.
  • How do I use Text Generators or Flash animations after upgrading to QuickTime 7.1.5? (Intel Macs only)
    • Text generators are Flash animations, and on the Mac the NuVJ Software uses QuickTime to play Flash files. Since version QuickTime 7.1.3, Apple prevents QuickTime to play Flash animations by default and requires to enable it manually by checking an option in the QuickTime preference panel. Under QuickTime 7.1.3, the NuVJ enabled this feature automatically at start up, but unfortunately Apple has changed the way QuickTime stores its preferences in Quicktime 7.1.5 and therefore the NuVJ software cannot automatically restore the QuickTime preferences. To fix this problem, you can: * Quit the NuVJ software if it's running * Download the little QTFlashFix application we have made available on the download page * Double click the .dmg file to open it * Double click the updater icon inside Then start NuVJ, and you should be able to play Flash animations and text generators again. We are working to fix this in the next NuVJ software update.
  • What is the maximum video file length?
    • There is no limitation in the length of the videos. Generally it is not a problem to use long videos, as they don't require any more memory than shorter ones.
  • How can I use the audio from a media player application in NuVJ?
    • When listening to the audio for BPM measurement or to display a Generator, NuVJ opens the 'default' sound recording device defined on your system. Under Windows, go in the Control Panel --> Sounds and Audio devices --> Audio --> Sound Recording --> Volume. Depending on the sound card, there might or might not be an entry to select the sound output of your computer as a recording device. Its name depends on the card manufacturer and is something in the flavor of "Wave Out Mix", "Stereo Mix", "What you hear", etc. If there is no such entry, check the Options / Properties menu to see if it can
  • Can I create my own effects?
    • It is not possible to create your own effects. But future NuVJ software updates will come with new effects.
  • How can I make sure my video device appears in the NuVJ video devices list?
    • Make sure the device in not in used by another application and verify that the latest drivers for your device are installed (web cam or PCI cards). Under Windows, any device compatible with DirectX (DirectShow, in this case) will work in NuVJ. You can also check the settings of your camera in NuVJ's camera setup (see User Manual). Under Mac OSX, any device compatible with QuickTime will work in NuVJ. Check that you can open your device in QuickTime to see if it is correctly installed.
  • Do you recommend using a laptop with NuVJ?
    • There is no particular problem with laptops. Laptops are often more suitable if you have to travel, but be sure to check the capacity of the graphic card and the amount of memory available. If you can, try to limit the resolution of your video loops because laptop hard drives tend to be slower and smaller than in desktop computers. Another solution if you use hi resolutions videos loops is to use an external Firewire or USB2 hard drive that spins faster than on-board laptop disks.
  • How can I get my Logitech web cam and the NuVJ to work together?
    • There may be some conflicts between NuVJ drivers and some Logitech web cam drivers. If you are in this situation, please contact Numark technical support.
  • What is the best video card to use with NuVJ?
    • NuVJ does support a very large range of graphic chips, from NVidia, ATI or Intel. On Windows, make sure you installed the latest drivers for your graphic card (usually you can find them on the manufacturer's web site). If your graphic board is not powerful enough some effects will just be disabled. Ideally the graphic card should support pixel shaders 2.0, all cards sold today supports this. Some laptops or some built-in motherboard chips don
  • How can I optimize my computer for smooth video playback?
    • There can be two different issues when dealing with movie files: a low frame rate or a delay when triggering movies. These two problems have different origins: 1. Low frame rate: In the status bar of the NuVJ window, you can see the frame rate. If the frame rate is below 20 FPS (frames per second) it will not be smooth. In most case this problem is due to the decompression of the movie, which takes too much resources for your computer. The solution in this case is to recompress the movie in a better format (QuickTime PhotoJPEG advised) or smaller resolution. 2. Delay when triggering: The delay when you start a movie can be due to two different factors: the lack of free physical memory, or heavy compression format. You can first try to recompress the movie in a better format. If it doesn't help, you should maybe use less visuals in your show, add some memory in your computer or regularly remove unused files buy using the Edit>Purge menu (see documentation for more details).
  • What codec is recommended for compressing video loops for NuVJ?
    • The recommended codec for VJing is the QuickTime PhotoJPEG codec. The resolution will have an impact on performances. The quality does not need to be 100%. Using a quality from 60% to 80% is a good option.
