DV300 Advanced Multimedia File Analysis with Magnet Verify
This 4-day course starts with training in detailed binary analysis of digital multimedia files, specifically focusing on the most common formats, i.e., ISO BMFF (MP4, MOV, 3GP, 3G2, M4V) and RIFF (AVI). Building from this foundational skillset, the course continues with a focus on troubleshooting video files with H264 encoded video, specifically focused on AVCC implementations of H264 encoding in ISO BMFF files.

This 4-day course starts with training in detailed binary analysis of digital multimedia files, specifically focusing on the most common formats, i.e., ISO BMFF (MP4, MOV, 3GP, 3G2, M4V) and RIFF (AVI). Building from this foundational skillset, the course continues with a focus on troubleshooting video files with H264 encoded video, specifically focused on AVCC implementations of H264 encoding in ISO BMFF files.
The course concludes with an overview of digital video authentication workflows, focused on structural analysis and metadata analysis. Attendees will learn techniques to compare digital encoding structures and train on Medex’s Reference Library of known encodings to be able to differentiate between original camera video, video that has been edited using software programs, video that has been reencoded by social media platforms, and videos that have been generated by deepfake software.
This course will also prepare attendees to use Medex in complex authenticity or file origin cases and provide expert opinion testimony in court.
