Try VideoWriter

video = VideoWriter('Movie.avi'); 
open(video); 
folder = 'D\Folder';
str = int2str(i);
for i=1:N 
  Image = strcat(folder,'\',int2str(i),'.fig');
  I = imread(Image); 
  writeVideo(video,I);
end
close(video);

Hello, Sudhakar Shinde

Thanks you for your replied, however when i run the code its apprear

"Error using VideoWriter (line 167)

A file name must be specified."

How to fixed this ?

Thanks in advance.

[Sudhakar Shinde]

can you try on command window and check if error observed or this is successful :

video = VideoWriter('Movie.avi')

[Trang Hu Jia]

When i try only this command

video = VideoWriter('Movie.avi')

It is successful

video =

ok so where is the error ? Is this error during execution of writeVideo(video,I); ?

Please look : https://www.mathworks.com/help/matlab/ref/videowriter.writevideo.html

[Trang Hu Jia]

I got an error when i manually run on this following line

Image = strcat(folder,'\',int2str(i),'.fig');
  I = imread(Image); 
  writeVideo(video,I);

At imread command it was error and shown as

  Error using imread>get_format_info (line 491)
Unable to determine the file format.

Error in imread (line 354)
        fmt_s = get_format_info(fullname);

[Sudhakar Shinde]

Have you added path of your image folders in 'folder' variable

[Trang Hu Jia]

Yes Sudhakar Shinde

video = VideoWriter('Movie.avi'); 
open(video); 
folder = 'E:\Thesis_PhD\Code_optimization\BESO_3D_MATLAB\Beam-SHS Column (Original)';
str = int2str(i);
for i=1:48 
  Image = strcat(folder,'\',int2str(i),'.fig');
  I = imread(Image); 
  writeVideo(video,I);
end
close(video);

This is my implementation of the code

[Sudhakar Shinde]

Can you attach fig file example here

[Trang Hu Jia]

Sure Sudhakar Shinde

But my .fig file are larger than 5 mbs.

Is there any possible way to attach the files ?

[Sudhakar Shinde]

fig file is not supported for imread. So it could not works. Check supported formats for imread by using command - 'imformats'.

One thought if there will not be any data loss , you can convert .fig to supported format and use above solution. But look for any kind of data loss during conversion.

It's best not to save your screenshots out as .fig files. You should save them as PNG instead. Or just create the video directly from the axes on the figure as you change it. See attached demos.
