Not only does the timeline support video and audio clips, but external triggers can also be added, for example to time lighting changes to video queues. Each timeline arrangement can function as its own separate piece of content that is triggered inside the program view.

Virtual Screens & Screen Slicing

Virtual screens are one the most powerful tools in Hirender S3. Custom dimensions and shapes can be created out of any content window using the screen slicing interface. This can be used for something as basic as a picture-in-picture view to complex cropping, masking and warping of inputs to map projections to different surfaces.

Projection Mapping with 3D Blending


One of the most popular uses of Hirender S3 is for projection mapping. Using the built-in 3D edge blending interface you can crop and warp projector outputs to any size and shape, as well as create smoothly blended edges using various effects and tools.

Multi-Machine Workflows

Hirender S3 installations running on multiple computers can be linked together over a local area network (LAN), enabling large-scale display environments with virtually unlimited outputs, all controlled by one master server. An example of this workflow was the 2022 Winter Olympics ceremonies in Beijing, which used multiple machines connected to an array of projectors all working in concert.

Preview Mode

When the primary and backup machines are connected via the LAN, the playback progress and media can be synchronized with just one click, ensuring the event continues to run smoothly.
