This code will work for all the video files with extension .mp4. If the extension is something else, then change the first line.
files = dir('*.mp4');
for i=1:numel(files)
current_path = fullfile(files(i).folder, files(i).name);
new_folder = fullfile(files(i).folder, files(i).name(1:end-4));
new_path = fullfile(files(i).folder, files(i).name(1:end-4), files(i).name);
mkdir(new_folder);
movefile(current_path, new_path, 'f')
end
