Explanation

This error message arises when loading video data. It indicates that the folder selected when browsing to load video data contains data that is not formatted as required by Theia3D (See Data Formats). The video data may all be located within a single folder (i.e. all video files together in one folder), instead of each video file being nested within its own folder with a matching camera ID folder name.

Possible Solutions‍

1. ‍Organize the videos, then try again.
   In order to load the desired video data, it must first be organized as required by Theia3D. This can be done using the Organize Videos tool under the Tools dropdown menu. For detailed instructions on the use of this tool, you can watch the Organize Tools tutorial video.
2. ‍Load the calibration file first.
   As indicated in the error message, data that is all located within one folder instead of within camera ID folders can be loaded if the calibration file for the movement trial is loaded before the video data. Using this approach, the video data will then be automatically organized within camera ID folders to meet the Theia3D data organization requirements moving forward.
