How to set the correct Player location ??

Hello. I am following the guideline below.

https://kr.mathworks.com/help/vision/examples/depth-estimation-from-stereo-video.html

I used stereo camera calibrator and export camera parameters. and I copy and paste the commend from the link.

Question 1. Regarding 'create video file readers and the video player',

player = vision.DeployableVideoPlayer('Location', [20,400]);

What is the meaning of the [20,400]??

Qeustion2. Regarding the 'Read and Rectify Video Frames', I copy and paste this part but I got an part of the rectified video frames. I can not see the original size rectified video frames. I guess it should be related with the ('location ,[20, 400]') or stereo calibration step..

Please help ..

Location is the place to position the bottom left corner of the player, in pixels, from the bottom left of the screen. The default is to put it in the middle of the screen

Thank you for your reply!

Then, in my case, should I put like this?

[-60000, 150000]

I am not clear.. please help.. Also, I don't know why the rectified video frame size is so small...

[Walter Roberson]

-60000 would put it somewhere around 130 metres to the left of your screen.

Either leave out the option or use 0 0 for now
