- Why are the Vuo Editor and Pro Nodes proprietary?
- What license does Vuo use?

Kosada is a small owner-operated company that has funded all of Vuo development out-of-pocket. We earned all of our Vuo start-up funds by doing consulting work and are not bound to any venture capitalist or shareholders. So that we can continue to rapidly develop Vuo on our own, we need revenue to sustain ourselves! Here's how we intend to sustain project Vuo:
With the free trial, you can open and edit compositions created by the Vuo community, and use nodes created by the Vuo community.
The free trial has no time limit — but saving, copying, and app exporting are disabled, exported movies are watermarked, and Pro features are disabled. The free trial does not include the SDK or the source code (but you can get the 1-year-delayed source).
After you have purchased Vuo, you can activate your copy of the Vuo Editor using its "Help > Activate Vuo…" menu item or the "Activate Vuo" dialog button presented each time the Editor is launched. You can even start editing a composition with the Vuo free trial, then purchase and activate Vuo without closing your Vuo Editor window, and you'll be able to save the composition you edited!
Vuo Pro has additional features geared towards professional settings on a commercial scale:
- Antialiasing and motion blur — When exporting a composition to a movie file (offline rendering via the File > Export > Movie… menu), Vuo Pro allows you to apply spatial supersampling (antialiasing) and temporal supersampling (motion blur)
- Art-Net — Vuo's
Send Art-Net Messagesand
Receive Art-Net Messagesnodes enable your compositions to control stage lights, or to be controlled by a stage lighting system
- 3D stereoscopic rendering — Vuo's
Make Stereo Camera,
Make Targeted Stereo Camera,
Render Scene to Stereo Images, and
Combine 3D Stereo Imagesnodes allow you to render and encode a 3D scene using an asymmetric frustum perspective projection, suitable for outputting to stereoscopic displays
- Fisheye camera — Vuo's
Make Fisheye Cameraand
Make Targeted Fisheye Cameranodes allow you to perform 3D fisheye projection, for use as an artistic effect or for projecting on hemispherical domes.
- Projection warping — Vuo's
Warp Image with Projection Meshnode enables you to project onto a dome with a spherical mirror, an inexpensive alternative to traditional planetarium projection systems. Besides warping images for dome projection, it can be used for any kind of image warping — for example: keystone correction, stereo image alignment, conversion between image perspectives, and projection mapping.
- Dark mode — Make Vuo Editor's interface dark
Our philosophy behind offering two tiers in pricing, Vuo and Vuo Pro, is to fund Vuo's continuing development by selling products geared toward two main audiences. The lower-cost option, Vuo, is geared toward people who will use it for DIY and hobby projects and low-budget productions. The higher-cost option, Vuo Pro, is geared toward people who will use it in paid work, selling services or products made with Vuo. Vuo Pro includes additional features that professionals can take advantage of in their work.
Although determining whether a feature should be Pro or non-Pro can be somewhat subjective, we consider several criteria when making the decision. A feature is likely to be Pro if any of the following are true:
- It requires the purchase of special hardware, such as stage lighting or a VR headset.
- It requires multiple computers.
- It interacts with advanced software, such as a database management system or a video editing application.
- It enables advanced graphics, such as 3D stereoscopic rendering or a fisheye camera.
- It enables exporting compositions to a format in which they could potentially be offered for sale.
When we open a feature request for community voting, we decide if it will be Pro or non-Pro. This is indicated on the webpage of the feature request.
Yes! We offer a 20% discount for college/university students, and for staff and faculty at all grade levels. Just use your academic email address (.edu, .ac.*, etc.) and send a photo/scan of your ID card to email@example.com. This can be combined with our bulk discount. (This discount doesn't impose any additional restrictions, so it's OK to use Vuo for commercial projects if you like.)
Yes, and yes! Check out our Gift and Bulk Discount page.
In 2013–2014, we sold Vuo subscriptions, but discovered that it was confusing. Our Vuo "free update" subscriptions let you keep using old versions of Vuo forever, even after your subscription expired. But since other companies offer subscriptions that don't let you do this, many people thought that a subscription meant that they'd only get to rent Vuo instead of getting a copy to keep forever. So, to make this crystal clear, we've switched to a simpler model.
Sometimes software platforms disappear or aren’t supported long term. Why should I invest my time with Vuo?
From the beginning, we’ve striven to create a platform that you can feel confident using. If you put your time and resources into Vuo, we want you to know that Vuo is going to continue to be around when you need it.
Kosada has a team of people working on Vuo. With a dedicated team, we can make improvements quickly. We can ensure the supporting documentation and tutorials are there, as well as providing ways to get your questions about Vuo answered.
And, if needed, you (or someone you hire) can work on Vuo. A Vuo license includes the source code for the compiler and core nodes, and we release that code publicly 1 year later. The rest of the code is held in escrow. The parameters of the escrow ensure that if Kosada ever disappears, or stops supporting Vuo, the Vuo Editor source code will be released to the public, ready for someone else to carry the torch.
Vuo seeks to integrate with the software below:
|CoGe||✔ CoGe version 1.6 and later can play Vuo compositions!|
|VDMX||✔ VDMX version 22.214.171.124 and later can play Vuo compositions!|
|Resolume||Vuo has a community feature request for exporting FFGL plugins. You'll be able to use these FFGL plugins in Resolume.|
|2V-P||Exploring this option.|
|QLab||Exploring this option.|
|Modul8||Exploring this option.|
|Millumin||Exploring this option.|
|MixEmergency||Exploring this option.|
|Bazik||Exploring this option.|
|Serato Video||Exploring this option.|
|Magic Music Visuals||Exploring this option.|
Integrating Vuo with VJ apps is an intricate collaboration between multiple teams. (This is why we're unable to post the timing of completion on our roadmap.) As soon as we know we are on track for full integration with another program, we'll post it!
If there's something you'd really like Vuo to integrate with, and you don't see it here, let us know!
All releases from Vuo 0.5.0 until Vuo 0.9.0 have been beta releases. A beta release is a release that is in a stage of significant development. With Vuo 1.0, Vuo will no longer be "in beta."
Vuo supports interfacing with many devices and protocols:
|Images||retrieve images from local filesystem and Internet|
|MIDI||send/receive Note and CC commands to/from music sequencers, control devices, and synthesizers|
|3D Meshes||load 3D mesh files via Open Asset Importer|
|Leap Motion||track hand gestures in air|
|Syphon||share video between applications on the same computer|
|Video File Input||playing back video from disk — including H.264, H.265, ProRes, Hap, and many more formats|
|OSC||control Vuo compositions with music sequencers and control devices (such as TouchOSC), and use Vuo to control OSC synthesizers and other devices|
|USB HID||use gamepads, joysticks, and other devices to control your Vuo compositions|
|Audio Input||receive and process sounds from multiple audio channels|
|Audio Output||play/synthesize sounds, receive and process external sounds|
|QuickTime video capture||MacBook Pro's iSight and other cameras|
|RSS Feeds||retrieve data from Internet|
|ArtDmx||control stage lights, receive commands from lighting consoles|
|Video File Output||writing video to disk|
|RS-232 Serial I/O||interface with microcontrollers such as Arduino|
Check out the community feature requests to see what's coming in the future, and to add your own ideas!
Vuo currently supports editing and running compositions on Mac OS 10.8 and later, and requires a 64-bit CPU. Apps exported from Vuo have the same system requirements.
Vuo is being built on cross-platform technologies. Eventually, we plan to also support at least:
- Running compositions on iOS, Android, Windows, Linux, and maybe Haiku
- Editing compositions on Windows, Linux, and maybe Haiku
Yep. Vuo includes a framework so you can write a C++ (or Objective-C++) app that can load a Vuo composition, start it running in the current process or as a separate process, control the composition, and receive data from the composition.
We're already working with the authors of several visual compositing systems to enable their software to play and control Vuo compositions. We'll be announcing more on this soon.
Here are a few ways you may extend Vuo:
- Create a new node by programming it using Vuo's C API.
- Create a new node by turning a composition into a node.
- Create a new data type for ports by programming it using Vuo's C API.
- Create a new input editor — the user interface that lets a user change an input port value in the Vuo Editor — by programming it using Vuo's plugin API.
- Add a user manual for a node set.
- Add an example composition for a node set.
You may also use add-ons other people have shared.
Will my previous Vuo compositions continue to work as new Vuo releases come out? Are Vuo compositions backwards compatible?
Team Vuo is fully focused on developing Vuo into an ultra-capable tool. Whenever we’re able, we will ensure that compositions from previous versions will continue to work in the latest version. However, due to the nature of major development, it’s possible that a new release may break a composition. If this happens, the composition will most likely only need a small adjustment to get it working again. If we anticipate that a new release might break older compositions, we will do our best to prepare you with solutions in the release notes. And if a composition doesn't work with a new release, it will continue to work with the older release you created it on.
If you have critical compositions, our automated test rig is available as a service.
You may submit your mission-critical compositions to our automated test rig for $35 USD per composition. Just email your compositions directly to firstname.lastname@example.org and we'll send you an invoice. (If a composition will require a significant amount of maintenance, we may need to charge extra — we'll let you know if that's the case).
After installing and activating Vuo on a computer, you may later want to deactivate it — for example, to make sure that your copy of Vuo is used on only one business computer at a time.
To deactivate Vuo:
- Log in to macOS with the same user account that you used to activate Vuo.
- Open Terminal.app.
- Enter the following text and hit Return:
defaults delete org.vuo.Editor

What are votes for?
Voting is the way the Vuo community decides the future of Vuo. Here's how it works:
- You can suggest features for Vuo.
- You can vote for your own feature request, or for features suggested by other people. Here are all the open feature requests.
- When it comes time for Team Vuo to plan the next release, we try to implement as many of the community's top-voted feature requests as we have time for. Here are the community feature requests we've completed so far.
How do I get votes?
By contributing to the Vuo community! For example:
- When you buy a Vuo license, or when you upgrade an existing license, you get 50 votes
- When you share your first composition, you get another 50 votes
- And when you share compositions after that, you get 5 votes each
- When you submit a helpful bug report, you get 5 votes
- When you contribute good code toward fixing a bug or implementing a feature, you get 5 votes
- When you create a tutorial and we add it to our tutorials page, you get 20 votes
How do I find out how many votes I have?
- Go to the feature request listing and check the "My available votes" box on the right side
- Or go to your user profile page and click the "Votes" tab
When you make a bug report, please:
- Review existing bug reports and contribute more information to them
- Provide precise steps that enable Team Vuo to reproduce the problem on the latest version of Vuo
- Reduce the complexity of your composition and steps to reproduce the problem
- Provide the simplest possible composition and steps that cause the problem to happen
- If possible, remove custom nodes from your composition
- Attach a crash report or process sample to the bug report
- In the top of the crash report window, there's a file icon. You can drag this icon to your desktop, to save it in order to attach to your bug report.
- If you've already closed the crash report window, or if Vuo disappeared without showing a crash report window, you can find crash reports by opening the Console app (in the Applications > Utilities folder), and looking under the User Diagnostic Reports list in the sidebar. Find the crash report for Vuo Editor or VuoCompositionLoader that matches the date and time the crash occurred.
- If Vuo Editor or your composition hangs, open Activity Monitor, select Vuo Editor or VuoCompositionLoader (it should be red, with the label "Not Responding"), and select View > Sample Process. In the window that appears, click Save…, and attach this file to your bug report.
- In the top of the crash report window, there's a file icon. You can drag this icon to your desktop, to save it in order to attach to your bug report.
- If you're experiencing performance problems, measure the framerate
OpenGL Profiler.app— if you don't already have it installed, go to http://developer.apple.com/downloads and download "Graphics Tools"
- Run your composition
- In OpenGL Profiler, select "Attach to application", then find your composition in the list and double-click on it
- In the bottom part of the window, you'll see two "Frame Rate" numbers. Post both numbers on your bug report.
How can I support people who share Vuo compositions? How can I get paid for Vuo compositions I share?
You can show your support to composition authors by making micropayments with Flattr or Paypal.
All transactions are made between two people through those payment services — Team Vuo does not collect any fee.
Great! We welcome code contributions from the community.
Although we publish Vuo's source code on GitHub, the GitHub workflow isn't ideal for us. Here's the process we encourage you to use:
First, please read the Vuo Contributor Agreement and be sure you understand it and agree to the terms.
If you're developing a new node, follow the process in Developing a Node Class. In particular, follow the conventions described in the "Naming node classes and ports" section. When you're ready to contribute your code, create a feature request, and attach the
.c file to the feature request.
If you're modifying an existing node, download the latest Vuo source code. Find the node you'd like to change, make a backup copy, make your changes, create a patch (in Terminal.app, run the command
diff -u vuo.node.backup.c vuo.node.c > ~/Desktop/vuo.node.patch), and attach it to a feature request or bug report.
Please state on the feature request or bug report that you understand and agree to the Vuo Contributor Agreement, and that you intend for this code to be integrated into Vuo.
We'll then review your code and, if possible, integrate it into Vuo. Since Team Vuo is responsible for ensuring that all of Vuo's nodes work properly and are consistent and well-documented, all of Vuo's built-in nodes go through an extensive planning, review, and testing process — and contributed nodes are no exception. This process may take some time, but we'll do our best to get back to you as soon as we're able.
Vuo development and licensing
Kosada, as creator of Vuo, owns copyright on the Vuo Core (compiler, editor, and built-in node sets). Kosada also owns the Vuo trademark.
Things you make using Vuo — compositions, node sets, compiled applications, generated images — are all yours. You own copyrights.
In order to make contributions to the compiler and core node sets, licensing requires that the copyright of contributions be transferred to Kosada — so that we may incorporate your contributions into Vuo. (This enables Kosada to act as the single legal steward of Vuo — so that we may enact the license cascade, and so that you, as a contributor, will be shielded from potential legal action taken against Vuo.)
Kosada (the company behind Vuo) plays the following roles:
- Develops, publishes, and provides support for the Vuo Core (the compiler, editor, and built-in node sets) and documentation.
- Works with the Vuo community to nurture contributions.
- Develops and hosts the Vuo community website.
- Markets Vuo, to grow the community.
- Provides consulting services (using Vuo to produce bespoke work).
Being able to see the source means you can take Vuo apart to see how it works. Knowing how Vuo works can be particularly helpful if you're developing your own nodes for Vuo, or if you want to integrate Vuo into an application you're developing.
Having the Vuo Compiler and core node source code also means that you have access to the full stack of software used by your Vuo compositions — your compositions will not contain any black boxes that block your ability to understand what's going on.
If we were to make all of Vuo source code available, it would be possible for a current copy of Vuo to be distributed free, Vuo revenue to be impacted, and for development to derail and fizzle from there.
So, in an effort to sustain Vuo (and Team Vuo) in the long-term, we’ve chosen an option that will both give you confidence in your investment in Vuo, and provide a little more security for our developers.
If you're a paying user, you get:
- the latest binary of the Vuo Editor and Pro Nodes under our proprietary license
- the latest source code of the Vuo Compiler and SDK under the GNU Lesser General Public License (LGPL) version 2 or later
- the latest source code of Vuo example compositions and non-Pro Nodes under the MIT license
If you're not a paying user, you get:
- Install the Vuo Editor on any number of computers you personally own
- Install the Vuo Editor on one computer owned by the business you work for
- Use Vuo for personal projects
- Use Vuo for commercial projects
- Distribute composition source code you create
- Distribute apps exported from compositions you create — but see also:
- Distribute rendered output of compositions you create
- Distribute applications you create that link with the Vuo Framework
- Distribute the Vuo Framework along with applications you create
- Examine and modify the Vuo source code for your own use
- Distribute applications you create using your modified Vuo source code
- Develop new Nodes using the Vuo API
- Develop new Nodes using code from Vuo Core Nodes and Vuo Core Types
- Distribute new Nodes you create
- Sell new Nodes you create
- Distribute the Vuo Editor
- Distribute the Vuo Framework by itself
- Modify the contents of the Vuo Framework
- Distribute the Vuo source code
- Distribute modifications to the Vuo source code
The Vuo Framework and compiled Vuo compositions use the ZeroMQ networking library. This library is licensed under the LGPL, and its licensing terms explicitly state that the copyright holders permit it to be used in commercial applications without requiring source distribution or a dual license.
Some Vuo nodes use LGPL code:
Decode Movie Frame, and
Get Movie Infouse FFmpeg and Hap (YCoCgDXT)
Receive Kinect Imagesuses libusb
These nodes (and compositions you create using these nodes) dynamically link to the LGPL code, so anyone is free to swap in a modified version of the LGPL code, and if you create a composition using nodes that use LGPL code, you are not obligated to distribute your source code.
The Vuo Framework does not otherwise incorporate LGPL code.
If you plan to distribute an application made with Vuo, and you are based in the United States, your application may be subject to United States Export Administration Regulations if it includes nodes that can access files via HTTPS, such as "Fetch Image," "Fetch Scene," or "Play Audio File". With nodes that access HTTPS files, your application will include the OpenSSL library for decrypting files downloaded via HTTPS.
The Leap Motion SDK Agreement allows you to distribute your Vuo compositions and exported apps, unless your apps meet Leap Motion's criteria for being a "Specialized Application":
“Specialized Application” means an Application which is: (i) sold, licensed, leased, or otherwise disposed of for a list price of more than US$500 or local equivalent, or more than US$240 per year or local equivalent if on a subscription, lease or similar basis; or (ii) sold, licensed, leased or otherwise disposed of as part of, or for use with, another application, system, machine or device (other than a personal computer), having a list price of more than US$500 or local equivalent, or more than US$240 per year or local equivalent if on a subscription, lease or similar basis; or (iii) designed for use, or that is primarily used, with or for control, whether direct or indirect, of industrial, commercial, military or medical equipment.
If your project meets those criteria, before you distribute your app, please contact Leap Motion to establish a distribution agreement.
Vuo and other visual programming languages
No. Though Quartz Composer was an inspiring platform for us, we built Vuo from the ground up with a new philosophy. To learn more, check out our comparison of Vuo and Quartz Composer.
No. Vuo and Quartz Composer are too different to be trivially compatible. Vuo does not import and edit compositions made with Quartz Composer.
Also, there are a couple related community feature requests:
Feel free to vote on the feature requests to help make them happen.
Although there are many differences from Quartz Composer, probably the most important is
Quartz Composer has been great! We used it for years — and we're designing Vuo to do more. Vuo is rapidly adding functionality (see our roadmap for details), and here are some things that you can do that aren't possible with Quartz Composer:
- has step-by-step documentation and tutorial videos
- exports your compositions to stand-alone apps with a single click (no need to learn how to use Xcode just to make your composition into an app)
- exports your compositions to stand-alone movies, with optional high-quality spatial supersampling (antialiasing) and temporal supersampling (motion blur) (Pro)
- has built-in support (no plugins needed) for many devices and protocols, including:
- Leap Motion
- Serial I/O
- Art-Net DMX
- has built-in support for reading barcodes in images
- has built-in support for playing Hap movies
- has built-in 3D perspective, orthographic, stereoscopic (Pro), and fisheye (Pro) cameras, with variable field of view, and which can easily follow objects through the scene (no trigonometry required; we took care of that for you)
- has built-in 3D spotlights, which can either point in a specified direction, or point toward a specified object
- has built-in support for rendering to multiple windows — QC can only output to a single window (unless you write a plugin)
- has built-in support for loading a wide variety of 3D mesh formats — you can easily use 3D objects others have shared
- has built-in support for warping images using projection meshes (Pro)
- has built-in support for 16bpc (64bpp) and 32bpc (128bpp) images (QC is limited to 8bpc (32bpp))
- has built-in support for multisampling, whether rendering to a window or rendering to an image
- has built-in parametric 3D mesh generation — you can use math equations to make 3D objects
- has built-in phase-accurate wave generator — you can make things move smoothly, even if you change the speed
- has built-in Simplex noise generation — you can make things move naturalistically
- has a modern shader-based OpenGL implementation (instead of QC's outdated immediate-mode OpenGL implementation) — giving you better performance (and paving the way for eventual mobile device support)
- has a real 3D scenegraph with hierarchical transformations — you can build complex 3D scenes that behave realistically
- has the ability to make any node synchronous (wait for results) or asynchronous (do it in the background) — giving you the flexibility to decide how you want your composition to work
- can make nodes execute only when you want them to execute (instead of every time a parameter changes, like in QC) — your composition wastes less time and energy
- compiles code (instead of continually interpreting it) — you experience faster execution
- automatically generates parallel code — your composition takes advantage of your computer's multiple processors
- has a first-class API for creating nodes and port types — you have full, documented support for making nodes and port types, without having to resort to the undocumented private API (like in QC)
- includes source code for the compiler, and core nodes and types — you can learn how it works, make improvements, and have security that you'll still be able to use your compositions in the long term
- values its users' input, and seeks it out to help chart Vuo's development direction
- has a dedicated development team working many hours every week to improve Vuo
- has a support team whose focus is helping you solve any problems that might come up — so you can focus on creating
