Can you pls post as a private message a temp login to your site please? This is probably be due to the responsive video plugin bundled with the theme clashing with rev slider. Needs a small fix. Will look into it as soon as I can.
If you have video uploaded into your server, you can use the video shortcode video_header and video_section bundled with the sample data.
Also are you using Vimeo video as one of the slides or as a single slide? If you just need the video only, you can avoid using revolution slider and theme should display fine on the page.
