"hugo" command doesn't include mp4 files while the server does

Hi,
I don’t understand why but though the local server works fine with the shortcode <video class="video-shortcode" preload="{{ .Get "preload" }}" controls> <source src="{{ .Get "src" }}" type="{{ .Get "type" }}"> There should have been a video here but your browser does not seem to support it. </video>
I noticed that videos wouldn’t appear in the html files produced. I noticed that those mp4 were not included at all in public/
