Embedding video in Drupal sites
vzaar uses the industry-standard mechanism for embedding third-party content in web pages - the iframe. As such, you shouldn't need any further tools or code to embed videos in your Drupal site.
However, some people prefer to use specific modules for managing videos and there is a vzaar module for Drupal: https://www.drupal.org/project/media_vzaar
Please note this is third-party code and is not created, maintained or supported by vzaar.
