I have used the following code to form a video from 287 frames but the 'baseFileName' is formed in the order - frame1,frame10,frame100,....frame109,frame2,frame20,........frame287.The for loop is working properly.So kindly help in finding the error.I found this code online.
myFolder = 'C:\Users\yourUserName\Documents';
if ~isdir(myFolder)
errorMessage = sprintf('Error: The following folder does not exist:\n%s', myFolder);
uiwait(warndlg(errorMessage));
return;
end
filePattern = fullfile(myFolder, '*.PNG');
pngFiles = dir(filePattern);
writerObj = VideoWriter('YourAVI.avi');
for frameNumber = 1 : length(pngFiles)
baseFileName = pngFiles(frameNumber).name;
fullFileName = fullfile(myFolder, baseFileName);
fprintf(1, 'Now reading %s\n', fullFileName);
thisimage = imread(fullFileName);
imshow(imageArray);
drawnow;
writeVideo(writerObj, thisimage);
end
close(writerObj);

The problem seems to come from the way the files are sorted when you read them into pngFiles. They look like they are sorted in lexicographic order. You might want to check this question on how to sort them differently.
