Series context. Earlier installments have focused on how modern evidence travels from device to docket, with attention to tool validation, human expertise, and admissibility. This part turns to video, where metadata, compression, and custody decisions determine whether a clip persuades a jury or collapses under scrutiny. [1][23]
1) What makes video “authentic” now
A video file is more than pictures in motion. It is a container of data and metadata, recorded by a specific device and exported through a specific workflow. Under the Federal Rules of Evidence, authentication can be established by testimony or by the evidence’s characteristics, including the process by which it was produced. Rule 901 sets out the general requirement, and Rule 902 provides self-authentication pathways for electronic records and device-copied data when verified by a qualified certification. Together, these rules allow parties to prove authenticity through processes and hashes, not just eyewitness testimony. [3][2]
Three metadata families often tip the scales.
