Try upload videofile

I use Laravel 5.4 and I try upload video file. Image file upload successfully.

$video = Request::file('video_file')) {
        $fullName = 'videos/'.uniqid().time().'.'.$video->getClientOriginalExtension();
        Storage::disk()->put($fullName, $video);

But it didn't work. When I try get information about file - size = 0

What I do wrong?
