Video Authentication by a forensic video / CCTV expert can detect edits or manipulations within fake video recordings. Although less popular than the manipulation of photos, edited video recordings for nefarious purposes are becoming increasingly common. This may include removing sections of a recording from the beginning, middle or end of a recording, or changing the time-stamps to a different time than the event. Mediums include CCTV DVR's and mobile phone video footage.
We can detect fake videos and if original videos have been manipulated through techniques such as differences in the hex structure and inconsistencies with the MAC times and format. There are many techniques at our disposal that the odds of getting an edited video past us are incredibly low.
