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.

Explanation

This error message arises when loading video data. It indicates that the folder selected when browsing for video data to load contains fewer than six camera views.

Possible Solutions

Theia3D requires six or more camera views in order to load any video data. If at least six cameras were used to collect the data, locate the missing videos and add them to the trial folder in properly formatted camera ID folders. If fewer than six cameras were used to collect the data, it cannot be loaded and should be recollected with six or more cameras.

Explanation

This error message arises when loading video data. It indicates that the videos from the selected trial are of unequal lengths.

Possible Solutions

Theia3D requires videos to be of equal lengths in order to be loaded. If your videos are of different lengths, this usually indicates an issue with your camera hardware setup or settings, or video download settings. For OptiTrack Prime Color cameras, verify that you have selected the correct video export settings, particularly Dropped Frames: Black Frame. If Dropped Frames: Drop Frame was used, this can result in exported video files being unequal in length, and the videos should be exported again using the correct setting.

Explanation

This error message arises when loading video data. It indicates that the videos files from the selected trial were written using an unsupported video chroma format for codec h264. Supported formats are 8, 10, or 12 bit YUV 4:2:0.

Possible Solutions

Theia3D requires video files to be encoded using certain supported video codecs and color chroma formats. If the videos you are trying to load were created with an unsupported video chroma format, they cannot be loaded by Theia3D. When this error is encountered, the best solution is to re-export or convert the videos to a supported chroma format.
