How about the following solution?

s = dir('*.png');
v = VideoWriter('output.avi');
open(v);
for kk = 1:numel(s)
    filePath = fullfile(s(kk).folder,s(kk).name);
    I = imread(filePath);
    writeVideo(v,I);
end
close(v);

You can simply adjust the image size just before combining them, like:

...
F_IR = imread(filePath_IR);
F_OR = imread(filePath_OR);
F_OR = imresize(F_OR,size(F_IR,[1,2])); % <- Added this line
bothImages = [F_IR, F_OR];
...
