A mechanism for adding and/or modifying annotations in embedded content from an embedding source is presented herein. The mechanism enables a developer of a website or application to add or modify annotations in embedded or referred content without owning the content. The mechanism may apply a set of annotation parameters including text, type (e.g., info cards), size (e.g., length/width), location (e.g., x/y coordinates), time (e.g., start/stop times), and/or a hyperlink (e.g., navigation endpoint) to add or modify the annotations within the content. Thus, the developer may use the mechanism to render and display the annotations at particular times and locations when the content is playing, as well as specifying what happens when the annotations are selected. The content may include video, audio, social media posts, or the like.
