Video Forensics: Standard Operating Procedures
There is a set of procedures all forensic experts follow in
order to show that their investigation and forensic work is acceptable in the
scientific community. Without these standard operating procedures, our courts
and legal systems will get bogged down by bogus forensic experts who provide
bogus information in litigation.
Following the practices and procedures of forensic
investigation as accepted in the scientific community requires the forensic
examiner to be trained on many levels of forensic investigation. For example,
software programs that aid in the forensic examination are complicated. Training programs both written and on video
help forensic examiners learn how to use and apply these software tools when
conducting forensic examinations.
In the following article, I will describe the processes I
often use as an audio video forensic expert as well as the tools that aid in my
investigations. I wrote this article about
digital and analogue video clarification to help the lay person better
understand the audio/video forensic examination and investigation process.
Many video recordings are submitted to me for forensics examination.
More often than not, the quality of these recordings is below optimal. Operator
error or inferior equipment often contributes to poor quality video.
Essentially, video clarification is the process used to
address these less-than-ideal video conditions–to produce a sharpened, enhanced
video product.
Our Mac and PC based forensic video processes allow us to
break a video down into its original components and enhance picture quality and
sound.
The components are adjusted and then realigned, resulting in
a clearer, crisper image. Once the video has been loaded into our computer, we
can then adjust gamma color tints and intensity, ratio of black to white to
grey tones, chroma, and other video attributes, plus sound-quality attributes.
Note that no video clarification steps used by a video
forensic expert will cause damage to the original recordings. Maintaining the
integrity of an original videotape is, of course, of paramount importance.
I want to stress the importance of using original video
recordings in all litigation because originals have the better quality than
copies and because originals that have an established chain of custody are
mandatory for court use instead of copies. Although the copy is showing the
same image, the information contained on the video recording will never be as
valuable as the original. Original videos outside the court room are referred
to as "Full Quality Files".
If you have any questions about original video vs. copies in
a court proceeding, call us for a pro bono phone conversation. If you believe that your audio or video
evidence is not authentic, then you should consider contacting a forensic
expert who can help guide you in obtaining an original copy of the evidence
that is being used in your court proceeding.
Ask the forensic expert for a copy of their curriculum vita so you can
see their experience and even contact some of their references.
In all instances–litigation and other publishing
uses–working with the original recording always produces superior results. The
master recording has integrity in litigation and is much higher quality than a
copy. If a video clarification process is necessary, mine is second to none.
