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.

Physics useful in forensics because it can be used to determine the original location of the blood spatters produced in the shooting. Physics can also be used to examine the trajectories in the murder.

For the victims of homicide, medical scientists to dig up information by performing an autopsy in the hope that evidence will appear in the bodies to help bring the perpetrators to justice.

Benefit of Professional Forensic Audio Enhancement in Crime Scene Investigation

The Forensic Audio Enhancement is a software toolbox designed for the enhancement of single-channel audio signals corrupted by a variety of noise environments typically found in forensic recordings. These are wideband noise, stationary tones, and interfering pulses.

Audio enhancement techniques have been useful both in a commercial setting – where lecturers and other speakers can have a discussion or explanation cleaned – or in situations where audio forensics that could mean the difference between conviction or acquittal.

If you want to get more information about best video enhancement software, you should visit reputable websites. While the improved audio quality end does not always come out loud and clear (there is only so much that can be done with the original audio in many cases) the end result is often surprising to read to the point where – if the audio properties of proof – will be allowed in court.

Public speakers often find great benefit from the additional audio when they perform at conferences and seminars. Recording of the seminar are usually sold after the fact for those who can not be present and if the speaker has a future Q & A where guests/audience is not wired for sound and then they hear after the fact only able to hear the speaker side of the discussion.

Audio enhancements can actually improve even these issues so that instead of removing the noise, certain sounds (such as conversations) can be strengthened and improved.

Of course, not all the forensic audio enhancement turns and some audio will be preserved all save for those who are trained to listen – and sometimes not even to them.
