The Institute of Oral History at the University of Texas at El Paso just produced a 2:49 video covering the 2014 annual conference of the National Council Public History in Monterey, California.   Using video from the conference and Monterey along with interviews, it highlights the value of the conference.  This was created by Karina Arroyo and Jesus Genaro Limon, who I believe are students at UTEP.  Perhaps your site could create something like this for your events or conferences with the help of a local college or university.
