MATLAB: Conversion image to video

image processingImage Processing Toolboxmake movietime lapsevideo

Hello, I am a total beginner on Matlab, and i am searching to convert an entire folder of .bmp images in a video file, with a specific rate of frame/second (like 25, 50 or 100 fps). I did see some explanations on the website, but did not succeed. Could someone give me some help, in order to create the simplest script ?

many thanks by advance.

Attached is an application I made to make a movie out of a folder of images. It's not fully done yet but it works. I think the only thing I have to do is to add the option to sort the filenames by time/date stamp instead of alphanumerically based on the filename (which is what it does now). But it's enough to get you started.

Why not read the error message and do exactly what it tells you to do? The message is quite helpful: "Call open(obj) before calling writeVideo" means you need to put this before your for-loop:

open(writerObj)

There is also a big clue that you close the object, but never open it.

The videowriter documentation also clearly shows that the video object is opened before being written. The documentation is there for everyone to read.

Please make sure your code is formatted correctly. It is barely readable.

Anyways, you didn't actually open the video writer object in your code. The line

writerObj = VideoWriter('YourAVI.avi');

Should be followed by:

open(writerObj);
