How to save Mechanics Explorer videos programmatically?

I am trying to find a way to automatically save videos rendered in the Mechanics Explorer of a Simscape 3D model after a simulation.
Ideally I would like to create videos from different view points and save to avi without user intervention after running the simulation (which already updates the graphics). I am just not able to locate the commandline equivalent of clicking the "Video creator" icon.

The Mechanics Explorer in Simscape models does not have a built-in command-line option for automatically saving videos after a simulation. However, you can use the MATLAB VideoWriter class to create videos from different view points and save them to AVI files without user intervention after running the simulation.
Here's an example of how you can use the VideoWriter class to create a video of a Simscape 3D model:
video = VideoWriter('myVideo.avi');
2. Set the video frame rate and open the video file for writing:
video.FrameRate = 30; open(video);
3. In the loop, get the current view of the model using the get function, and write the frame to the video:
for i = 1:numFrames % Update the view of the model
view(i,:) = get(gca,'CameraPosition'); % Write the frame to the video
writeVideo(video,getframe(gca));
end
4. Close the video file after the loop:
close(video);
