# Video Overlays

Video overlay (AVI) files can be saved after analysis of a movement trial is completed, and can be saved from within Theia3D or Theia3D Batch. These videos show any [display options](/axiom-v2025/theia3d-documentation/theia3d-dropdown-menus/display-menu.md) of the tracking produced by Theia overlaid on the original video files, which can be useful for Quality Assurance or demonstration purposes.

To save video overlays from Theia3D, use the Save Video Overlay button in the sidebar or under the File dropdown menu.

To save video overlays from Theia3D Batch, select Save Videos and any desired display options and camera views to be saved, prior to running the analysis.
