how to save multiple depth camera data

Hi, I try to save pointcloud from two depth cameras at once in rviz. I can view combined point cloud from two depth camera through rviz. But I can't save it simultaneously. I only found the way that saves one point cloud from one depth camera. Is there anyone who knows the way to save several depth camera's point cloud at once in rviz?

I'm running linux, intel realsense.

I think there is quite some misunderstanding about the tools here.

rviz is a visualization tool. You cannot use it to save any sensor data.

To save any ros topic, you can use the rosbag command utility. There, you can save the topics "simultaneously", i.e. record them with their respective time stamps. This means they are recorded at the time they are received, this might be at the same or at another time.

Is this answering your question? If not, can you please elaborate on what you actually want to do?
