smpteconnect just posted a video of Patrick Renner’s talk “Media Hash List (MHL) Format – Improving Data Integrity in Digital Cinematography” on SMPTE Annual Technical Conference 2011 on YouTube:

“In digital cinematography complete and correct backup of source media is one of the essential activities of the file-based workflow. In order to verify the completeness and correctness of a backup at any time, this paper proposes an XML-based Media Hash List (MHL) format—containing all the necessary information needed to detect possible errors during file copy and transfer. Presented by Patrick Renner (Pomfort GmbH, Germany) at the 2011 SMPTE Annual Tech Conference and Expo Oct 25-28, Hollywood, CA”
