How to obtain the data of point cloud and save that as a video?

Hello, I am a newcomer in using Astra camera.
Now, I need to record the movement of mouse(animal) and make a video for 1 hour.
However, I am not clear about how to obtain the data of point cloud of each frame and then save the frames(such as 1000 frames) as a package. Furthermore, how to make a video (1 h) by the frames?

Thank you for any suggestion.
