I am trying to play two video files one below the other at the same time. The videos are of different dimension. I tried this code but get an error saying "Dimensions of matrices being concatenated are not consistent."

I understand the error because frame sizes are different. but how to correct the code?

Frame2:- 681x1429x3 single

Frame1:- 525x700x3 single

Also, I tried to play two videos of same dimension, it worked but was zoomed in . How do I zoom out and play the videos as is?

if true
{
vid1 = vision.VideoFileReader('R1.avi');
vid2 = vision.VideoFileReader('FR2.avi');
vidP = vision.VideoPlayer;
while ~isDone(vid1)
 frame1 = step(vid1);
 frame2 = step(vid2);
 frame = vertcat(frame1, frame2);
 step(vidP,frame);
end
release(vid1);
release(vid2);
release(vidP);
}
end
