Best Answer

videoread = vision.VideoFileReader('YourFile.avi');
i = 0;
hold on
while ~isDone(videoread)
    i = i + 1;
    frames = step(videoread);
    imwrite(frames,['Image' int2str(i), '.jpg']);
    im(i)=image(frames);
    drawnow()
end
release(videoread)
However, I do would recommend you consider removing the image() call, as you would simply be putting image on top of image. It would make more sense to,
videoread = vision.VideoFileReader('YourFile.avi');
i = 0;
hold on
while ~isDone(videoread)
    i = i + 1;
    frames = step(videoread);
    imwrite(frames,['Image' int2str(i), '.jpg']);
    if i == 1
      all_images = frames;
    else
        all_images(:,:,:,i) = frames;
    end
end
release(videoread)
after which you could
implay(all_images)
