How to insert a video what would it be adaptive?

<div class="container">
 <div class="row">
 <div class="col-md-6">
 <video playsinline="" autoplay="" muted="" loop="">
 <source src="/video/promo.mp4" type="video/mp4">
 <div class="col-md-6">

The unit is divided into 2 parts, but the video goes beyond how to make so that it was clearly in his unit, and was known as 'rubber' on different extensions?
