For the ones who are interested.
If you want your Vimeo video to show only the video, without any controls or borders around it, try the following:
- Choose the 'Default' theme in the PrettyPhoto settings.
- Add the following CSS:

div.pp_default .pp_content, div.light_rounded .pp_content,
div.pp_default .pp_content_container .pp_details .pp_nav,
div.pp_default .pp_top,
div.pp_default .pp_bottom,
div.pp_default .pp_content_container .pp_left,
div.pp_default .pp_content_container .pp_right { background: none !important;
}
.pp_top, .pp_bottom,
div.pp_default .pp_content_container .pp_details,
div.pp_default .pp_content_container .pp_details .pp_nav,
div.pp_default .pp_description,
div.pp_default .pp_expand { display:none !important;
}
