The scientific examination, comparison, and evaluation of video in legal matters are known as forensic video analysis according to accredited national and international video forensic organizations like LEVA, NATIA, and IAI. To process the video recording with integrity and accuracy, the video forensics process must be carried out in a forensic laboratory outfitted with the appropriate tools and adhere to best practice protocols.
An eyewitness account of events in real-time can be provided by video footage. However, video cannot be accepted as evidence in a court of law without being thoroughly examined. Litigators and law enforcement officers use video forensics for this reason.


Process Of Evidence Collection

Most video evidence is in digital formats. Digital video recorders (DVRs) commonly record video to a hard drive; however, a record to secure Digital (SD) cards and other removable media.
There are many kinds of DVR devices, and each has different ways to export files. The device should produce recordings of the highest possible quality when the video is collected. The Scientific Working Group on Digital Evidence (SWGDE) has outlined best practices that forensic professionals must adhere to when conducting a Forensics Video Analysis. These include downloading and examining files correctly to guarantee that the video is accurate and unaltered.

Examining the Evidence

The forensic scientist begins examining the video by viewing the footage after the evidence has been collected. After a first viewing, they identify the areas of interest that require further investigation and enhancement. The forensic expert might look for evidence that backs up statements made by witnesses or identifies suspects.
To ensure that the video accurately depicts the crime scene, all forensic video analysis must be carried out in a forensics lab with the appropriate tools and following industry guidelines.

Phase Of Video Enhancement

Researchers in video forensics never alter recorded data. Instead, they enhance what is already there through a variety of methods. Among these strategies are:

  • Sharpening: Enhancing the clarity and discernibility of the recording’s edges.

  • Stabilization: Reducing the video’s motion so that it plays as smoothly as possible.

  • Masking: Protecting a victim, witness, or law enforcement officer’s identity by covering their faces or other areas.

  • Interlacing: Creating the full frame by combining two television fields.

  • Demultiplexing: In different camera systems, isolating each camera view.

 Ways Video Forensics Is Used In Court
A video forensic scientist can look over and improve video footage before using it as evidence in a trial. The expert witness consults with the litigants, provides formal reports on the forensic video analysis, and may testify in court. Whether a jury or a judge, the trier of facts needs assistance in comprehending the video evidence from an expert witness.
Details like these are included in reports and testimony:

  • The kind of handling that was performed.

  • Any examination restrictions.

  • How the request is structured.

  • The outcomes achieved

  • Explanation of any recording anomalies.
