How Video Analysis Is Done?
- Preliminary Analysis
Experts inspect the video and perform initial testing to determine the scope of the investigation. They prefer to only enter investigations if we feel our forensic services will be of assistance to the case.
- Digital Integrity Verification
Digital integrity verification testing will generally reveal any evidence of tampering first. The types of testing we perform include HASH verification, meta-data, EXIF and HEX testing to name a few.
Experts can also provide exemplar (controlled sample) comparison testing to determine if a recording is consistent with what we would expect to see from an original.
- Pixel/Frame Analysis
Sometimes our investigations require further testing to confirm authenticity. Frame by frame, motion vector, macro-block as well as physical equipment testing is required to determine the authenticity of recordings based on the behaviour of video pixels, as well as individual video frames.
