Table 3. Naming conventions and structure of all files available in the database.

〈ID〉 ∈ {1,2,…,90} indicates the subject number,〈round〉 ∈ {F,S1,S2,I1,I2} the data collection round, and 〈camera〉 ∈ {PG1,PG2,CP1,CP2} the camera type where PG stands for the computer vision cameras and CP for the cellphone cameras.

Data Type	File Name	Description
Video Data	〈round〉_〈camera〉_Subject_〈ID〉.〈format〉	avi video data from the computer vision cameras (PG1, PG2) for rounds F, S1, and S2, and mp4 video data from the cellphone cameras (CP1, CP2) for all rounds (F, S1, S2, I1, and I2) and all subjects (1-90). Note that we provide code to trim the video sequences to single motion clips for round F.
Camera Parameters	cameraParams_〈camera〉.〈format〉	Contains the camera intrinsic calibration data for camera PG1 and PG2 in .mat, .npz, and .pkl formats. These parameters are fixed for the whole dataset.
	Extrinsics_〈camera〉.〈format〉	Contains the camera extrinsics parameters for camera PG1 and PG2 (rotation matrix and translation vector) in .mat, .npz, and .pkl formats.
Motion Capture Data	F_amass_Subject_〈ID〉.mat	Contains the full markerset motion capture data (round F) processed by MoSh++ in the AMASS project and augmented with 3D joint positions and metadata for each subject (1-90). All files are compressed and stored as F_AMASS.tar. The original npz files and the rendered animation files are available at https://amass.is.tue.mpg.de/. Note that we provide code to trim the motion capture sequences to single motion clips.
	F_v3d_Subject_〈ID〉.mat	Contains the full markerset motion capture data (round F) processed by Visual3D and augmented with metadata for each subject (1-90). All files are compressed and stored as F_Subjects_〈ID〉_〈ID〉.tar as containers of 45 subjects (e.g., ID 1-45, ID 46-90).
	S_v3d_Subject_〈ID〉.mat	Contains the motion capture data from rounds S1 and S2 processed by Visual3D and augmented with metadata. All files are compressed and stored as S_V3D.tar.
IMU Data	imu_Subject_〈ID〉.mat	Contains the processed IMU calculation files augmented with metadata. Each file contains the data collected in all rounds (S1, S2, I1, I2). The files are compressed as IMUmatlab_Subject_〈ID〉_〈ID〉.tar containers of 15 subjects (e.g., ID 1-15, ID 16-30 etc).
	imu_Subject_〈ID〉.bvh	Contains IMU in .bvh format. Each file contains the data collected in all rounds (S1, S2, I1, I2). The files are compressed as IMUbvh_Subject_〈ID〉_〈ID〉.tar containers of 15 subjects (e.g., ID 1-15, ID 16-30 etc).
