Well you stated that you've tried a lot of things, but you didn't provide any code with it so that's not really helpfull. I suggest taking a look at how to acquire images from your webcam and after that it should not be that hard to create a video using VideoWriter. Hint: create a for-loop/while statement to continuously capture images from your webcam.

Well I suggest to use VideoWriter instead of movie2avi because according to the release notes it was removed after R2016b. If you still insist on using movie2avi, please read itsdocumentation. There's an example given and explanation on how to set the framerate.

I've used this code then it is saving the video but it's not playing when I go to that folder andplay with media player:
I'll be thankful if you may help
cd ('E:\8th semester\Machine vision LAB\Talha Data for open ended lab')
cam = webcam;
writerObj=VideoWriter('MyAVI.avi');
open(writerObj);
for i=1:60
filename = sprintf('153MC%0d.png', i);
imwrite(snapshot(cam),filename);
b=imread(['153MC',num2str(i),'.png']);
writeVideo(writerObj,b);
end
close(writerObj);
