How to send video via form/ajaxform?

Question

CMS

There is a need to send photo / video content through the form.
Everything is ok with the photo, but not with the video. If there is only a photo in the selection, the letter is successfully sent and received, in the case of a video, the letter is successfully sent, but does not come to the mail.

I'm using formit + ajaxform Thanks

in advance for your help.

Form call code:

The form itself:

<form action="#" method="post" class="ajax_form" id="reviewAjaxForm" enctype="multipart/form-data">
  <div class="add_add-rating">
      <span>
          Оцените товар:
      </span>
      <div class="add_add-rating-imgs">
          <img src="/assets/imgs/icons/products/star.svg" class="rating-star" alt="" data-rating="1">
          <img src="/assets/imgs/icons/products/star.svg" class="rating-star" alt="" data-rating="2">
          <img src="/assets/imgs/icons/products/star.svg" class="rating-star" alt="" data-rating="3">
          <img src="/assets/imgs/icons/products/star.svg" class="rating-star" alt="" data-rating="4">
          <img src="/assets/imgs/icons/products/star.svg" class="rating-star" alt="" data-rating="5">
      </div>
