Troubleshooting real-time streaming

Real-time streaming takes a large amount of processing power, and you may find the need to optimize your setup.

When streaming live, check in the QTM status bar that the real-time frequency is the same as the capture frequency.

If the real-time frequency is decreased, there are some steps you can take to optimize it:

  1. First, close any unnecessary windows in QTM, such as the data and trajectory info panes.

  2. Then, open Project Options, navigate to “Processing,” and make sure that “Process every frame” is not selected and that only the necessary processing steps are enabled.

  3. If AIM models or 6DOF calculations are enabled, check the individual settings pages to make sure that no unnecessary models or rigid bodies are included.

  4. Next, navigate to “GUI” to check the screen update frequency. You can lower the real-time mode or even deselect the checkbox to disable the QTM display during preview. This will reduce the load on QTM, freeing up its capacity to process the data.

  5. You can also navigate to “Input Devices” à “Camera System” to lower the real-time frequency.

  6. By default, it is set to the same as the marker capture frequency, but you can select “Reduced real time frequency” to apply a lower value.

  7. Click “OK” to save your settings.

If QTM is still struggling to process your real-time data, some of the following steps may help:

  • Close any unnecessary software running on your computer.

  • If streaming to an external program, you may have better performance running the program on a different computer connected to the same network.

  • You can also try starting QTM in server mode to minimize interference.

  • Finally, you may want to consider capturing with a reduced number of cameras so that QTM has less data to process.
