I'm doing a video with with a series of images I took a camera but they are saved in a numeric way so I need to get the images and de video separatly.
I'm being able to get the video. How do I get the also the images in a specific folder.
I'm using the next code:
for i=1:size(array)
frame = getframe(gcf);
writeVideo(v,frame);
close
end
close(v)

UA - please clarify what you mean bey get frames of video and/or how do I get also the images in a specific folder. Are you having trouble reading (or loading) the images from a particular folder? Is the order of the files incorrect? Or do you want to save the frames of the video as images? In your above code, what is array? Is it initialized to a set of images or is it something else?

The array is a series of numeric values that compose the image for each frame. I’m being able to read the array, create the video with the code but I cannot get the image of each frame separately.

See my attached demo. I use it to read in all the frames of a video and then, optionally, write them out to individual image files. Then, optionally, read in the individual image files from disk to create a new movie.
