Is there a way to pause matlab script while smvideowrite records a multi body animation?

Is there a way to pause matlab script while smvideowrite records a multibody animation? I have a Simulink model which I am sweeping through many data-sets so creating the animations programmatically in a loop is the only realistic way of processing the set; however rerunning the Simulink model will clear the mechanics explorer smvideowrite needs open to complete an animation. Currently I'm using pause statements to try to give the writer enough time to finish an animation but haven't been sucessjust ends up getting behind and failing anyway eventually. If there is some way to pause the script until video writer closed I would love to know about it!

You can work around this issue.

% simulate the model
sim("myModel");

% start writing the video 
tic;
smwritevideo("myModel","myVideo.avi");
toc;

% wait for the video to complete writing by checking if you can read it
whileFlag = true;
tic
while whileFlag
  try
    a = VideoReader("myVideo.avi");
    whileFlag = false;
  catch e
    counter = counter + 1;
    pause(1)
  end
end
toc;
