MATLAB: How to create one .avi-video from a folder with i.png files

Question

Hi, I have a folder with 20000 .png files named 1.png, 2.png, and so on until 20000. I would like to make a .avi-video of it. The size of the entire folder is about 90MB. I read the documentation about the video writer but it did not address this specific problem.

I wonder if someone could help or suggest me which commands to load and and make the .png to a video file.

I thank you in advance for your help

Answer 1

writerObj = VideoWriter('YourAVI.avi');
open(writerObj);
for K = 1 : 20000
  filename = sprintf('%d.png', K);
  thisimage = imread(filename);
  writeVideo(writerObj, thisimage);
end
close(writerObj);
