# JSON Files

Movement data for tracked people from a processed trial can also be exported to .json file format for more open-ended use in scripting environments and as an easily readable file output format. Use the Save Skeleton Poses button to save .json output files, or navigate to Save Skeleton Poses under the [File Menu](/apollo-v2024/theia3d-documentation/batch-processing/file-menu.md).

Output .json files contain:

* Theia3D version number, engines, and kinematic model information
* Trial frame rate
* Preferences used during process, such as start/end frame, max people, smoothing frequency, etc.
* Tracking data for each tracked individual, including ID number, segment names and 4x4 pose matrices, and parameters such as segment length.
