Boost your
iGaming experience

Composer is the real-time video compositing software, designed to guarantee authentic live casino experiences at 24/7 large-scale operations.


Composer is a real-time video compositing software for event-driven video compositing, color correction, chroma-key, visual effects, and live streaming. Composer runs any number of video sources, visual effects, compositions/layers, and outputs, with lossless processing without frame drops.

Cost effective and easy to scale

Composer is a software solution that consolidates all the essentials for live studio production into one convenient package. Traditional studio configurations involve numerous components such as vision mixers, chroma keyers, stillstores and encoders, leading to an array of challenges including complicated setups, scalability issues, automation difficulties, costly monitoring and expense. Also, with the expansion of the studio, managing rack space and handling extensive cabling becomes a considerable hurdle.

Composer offers a solution to all these challenges by providing an all-in-one platform capable of managing up to 16 cameras and 16 outputs, all within a single server. The only restriction lies in the server's capacity (CPU, GPU, bandwidth).

Composer's built-in APIs, automation capabilities, and monitoring support make the operation straightforward and manageable.

  • Easy to operate
  • Cost efficient
  • High density
  • Limited cabling

One studio - multiple outputs

Composer's incorporation of chroma keyers and compositing capabilities enables the creation of configurations that can produce several outputs from a single table setup. By eliminating the need for multiple chroma keyers, video switchers, and encoders, a single Composer server instance has the potential to deliver up to 16 video outputs.

This makes Composer an unrivaled cost-effective solution for chroma key configurations.

Integrated switcher and media storage

Use Composer as a video switcher, or vision mixer, for audio/video coming from up to 16 camera inputs or other media sources.

The switcher feature can be easily controlled from external applications using the built-in API.

Beyond simple transition capabilities, such as changing from source A to source B, Composer offers a wealth of advanced options. Using the Connectors feature, you can design macros that trigger a combination of actions, including;

  • Switching to a specific source
  • Altering the background image
  • Starting video clip playback
  • Toggling graphic layers
  • Changing the volume of selected audio tracks
  • Modifying the chroma keyer's backdrop

... and many more. These settings are fully adjustable and straightforward to implement using the Live Editor.

Layered compositions and branding

Composer is a toolbox that allows you to create a wide range of outputs. Anything from a single camera+color correction+h264 output, to multi-camera, multi-scene, multi-branding and multiple outputs. Or, use Composer as your encoder for up to 16 studios. The high performance video engine utilizes the full capacity of your GPU and CPU, and the built-in video encoder supports hardware accelerated encoding using NVENC. Use your Windows workstation to setup your project, and deploy the solution to your Linux- or Windows production environment.

Live editor

The Composer's integrated editor offers an effective tool for Product Owners and the design department, enabling them to obtain immediate results. The Live Editor dynamically renders the project, giving a precise visualization of the final output in real-time. Once the project is finalized using the Live Editor, the Composer runtime module allows for effortless deployment on Windows or Linux platforms, providing a lightweight solution.

  • Live rendition of all layers, inputs, and assets
  • View all effects in real-time
  • Drag-&-drop of layers
  • Audio VU-meters
  • Transparency preview
  • Color picker
  • Multi-scene setups
  • Runtime & performance monitor

High end chroma key

The built-in IB3D Chroma Keyer, the HSV Keyer and Color Difference Keyer, are capable of producing high end chroma key results. Composer supports 4K resolution, 4:2:2 capture and processing in 4:4:4:4.

The compositing engine of Composer allows a single keyer to be used as the source for multiple outputs. This translates to a more cost efficient setup as only one keyer is needed per camera or video source.

Composer also supports switching between multiple keyers, which is a requirement in multi camera setups.
