Motion FPS

[SreehariRajan]

I would like to know the FPS of the motions in the dataset.

The duration of the motions and videos in the synthetic videos is not the same. Can you explain why?

Hi, thanks for the detailed questions.

Here is the breakdown regarding the FPS settings:

Motions: Following the standard convention of most motion datasets (e.g., HumanML3D), our motion data is formatted at 20 fps.

Videos: For the video data, we follow the reference setting of Wan2.1, which has a native frame rate of 16 fps.

Regarding the duration/FPS discrepancy in synthetic motions: The process involves first extracting motions from the 16 fps videos using visual mocap (resulting in raw 16 fps motion data). To ensure consistency across the entire dataset, we then apply linear interpolation to upsample these motions from 16 fps to 20 fps.

Let me know if you have any further questions!
