How to add video file?

You are probably better off using a third party, as videos are huge. See my answer here: https://laracasts.com/discuss/channels/laravel/i-want-to-make-a-site-that-streams-movies-just-like-laracast-stream-video-tutorials

you can upload videos like images . You can use jobs :) I am using video js in my current project with vue. you have to specify src to video .

<video
   id="video"
    class="video-js vjs-default-skin vjs-big-play-centered vjs-16-9"
    controls preload="auto"
     data-setup='{"fluid":true,"playbackRates": [0.5, 1, 1.5, 2,2.5] }'
     :poster="thumbnailUrl">
        <source type="video/mp4" :src="videoUrl"></source>
  </video>
