Description

Hi,

I noticed in the `kubric_movif_dataset.py` that the frame rate is randomly chosen with `frame_rate = np.random.randint(1, int((120 / seq_len)) + 1)` when `random_frame_rate` is enabled. I am curious about the reasons behind choosing 120 as the fixed value in this calculation.

Thank you for your clarification!
