Input directory has no mp4 or avi files

Explanation

This error message arises when attempting to use the Organize Videos Tool to organize video files as required by Theia3D. Theia3D requires video data to be .mp4 or .avi file formats, so if the directory selected for organizing contains video files of a different format (e.g. .mkv, .mov, etc.) Theia3D will be unable to organize or load these videos.

Possible Solutions

To ensure your video data can be organized, loaded, and processed by Theia3D, they should be in .mp4 or .avi file formats. If possible, re-export the original videos to the correct file format, or convert the existing video files
