I have 200 images, each one is an instantaneous frame captured each 0.1 sec. Therefore, I would like to create a video of 20 sec using all 200 frames. Anyone can help? Thanks and Regards.

I have already had a look at it and I generated the following codes:
close all; clear all; clc; tic; myFolder = 'C:\Users\Desktop\Test'; if ~isdir(myFolder) errorMessage = sprintf('Error: The following folder does not exist:\n%s', myFolder); uiwait(warndlg(errorMessage)); return; end
