constructing a video from a sequence images

Hi everyone

I got this code from internet, and trying to get the images from a video, then converting them into a video.

But, I am faceing a problime that the sequence of the formed video is not worling because some of the images

jump a head on each other,

like it works with image ( image 001) to ( image 010 ) then it jumps to ( image 100 ) to ( image 200 ) to start again from( image 002)

and so on .. weling to get the help from you all

Sorry I couldn't attach the video to this massege, you can use any short video..

Thanks in advance

 clc, clear all, close all

workingDir = tempname("Vedio\12");
mkdir(workingDir)
mkdir(workingDir,'images')
shuttleVideo = VideoReader('Selfie.avi');

ii = 1;

while hasFrame(shuttleVideo)
   img = readFrame(shuttleVideo);
   filename = [sprintf('%01d',ii) '.jpg'];
   fullname = fullfile(workingDir,'images',filename);
   imwrite(img,fullname)    % Write out to a JPEG file (img1.jpg, img2.jpg, etc.)
   ii = ii+1;
end
%
imageNames = dir(fullfile(workingDir,'images','*.jpg'));
imageNames = {imageNames.name}';
%
outputVideo = VideoWriter(fullfile(workingDir,'Selfie_out.avi'));
outputVideo.FrameRate = shuttleVideo.FrameRate;
open(outputVideo)
%
for ii = 1:length(imageNames)
   img = imread(fullfile(workingDir,'images',imageNames{ii}));
   writeVideo(outputVideo,img)
end

close(outputVideo)
%
shuttleAvi = VideoReader(fullfile(workingDir,'Selfie_out.avi'));

ii = 1;
while hasFrame(shuttleAvi)
   mov(ii) = im2frame(readFrame(shuttleAvi));
   ii = ii+1;
end

 figure 
 imshow(mov(1).cdata, 'Border', 'tight')

movie(mov,1,shuttleAvi.FrameRate)

It depends on the order in which you are reading the image files. If you want to check this, look at your imageNames variable and its contents and order

Change your filename for images to below if you have less than 10000 images

filename = [sprintf('%06d',ii) '.jpg'];

It's always better to have the filename with a trailing 0 before the iteration number.

Or even better:

filename = sprintf('%06d.png', ii)
