In recent years, a host of online video providers have allowed users to create, upload and maintain high-quality video. Given the ease of access and level of service these providers offer, we no longer support uploading of video files directly to the website. 

We encourage you to upload your videos to Youtube or Vimeo, and use the Responsive Video Snippet to embed them into your page. Remember to follow accessibility guidelines regarding videos; see Web AIM's site on rich media accessibility for information on creating accessible video captions and transcripts
