How to install Swing Catalyst Motion Capture components

Important Notice

This guide covers Swing Catalyst 25.1 and 25.2. From version 26.2, the motion capture components are downloaded from the Optional Features settings page. See Optional Features: downloading motion capture components .

This feature requires a specific license type. Please check our FAQ for licensing details.

If you have received a self contained version for testing, you do not need to install any additional components.

Overview

This guide walks you through installing the necessary components to optimize Swing Catalyst Motion Capture performance. These components are specifically required for CUDA and TensorRT execution providers. Note that DirectML users can skip this installation as no additional components are required.

System Requirements

License Requirements

Valid Swing Catalyst license with Motion Capture functionality

Storage Requirements

Minimum 5.9 GB free space on C: drive

Hardware Requirements

NVIDIA graphics card supporting CUDA or TensorRT (GeForce or RTX series GPU), such as:

NVIDIA RTX 3070, 3080, 3090 series (minimum 6GB VRAM)
NVIDIA RTX 4060, 4070, 4080, 4090
NVIDIA RTX 5070, 5080, 5090

Other NVIDIA graphics cards may work as well.

Installation Process (Swing Catalyst 25.2 or newer)

Step 1: Start Swing Catalyst

Go to Settings -> Video & Capture
In the Motion Capture section, select TensorRT.
Click the Download button.

Step 2: Compiling the engine

Once the download is finished it will load TensorRT which may take a few minutes, wait for it to complete (the spinner indicator on the MoCap button will disappear).
When completed go to capture mode and make a recording, this will make the TensorRT engine compile and optimize itself for your hardware. This process may take around 10-15 minutes depending on hardware.
