New Video Evidence Recovery and Analysis Training and Software

We are very pleased to be able to offer investigators and examiners some new software and training.

In addition to the DVR Examiner software we are now able to supply iNPUT-ACE software and the Cellebrite VERA course.

I will be putting up more information on the website soon but here are a few words about the software and training;

iNPUT-ACE and iNPUT-ACE | Lite software packages provide investigators with powerful tools to manage their digital video evidence. The two dynamic software programs work alongside each other to expedite any case that involves video evidence: from video playback, to clip extraction, enhancement, analysis, report writing, and much more.

Video Evidence Recovery and Analysis (VERA) Course (To be held in the UK)

The Video Evidence Recovery and Analysis Course (VERA) is five-day intermediate level course designed to introduce investigators, examiners and analysts to digital video technology and to meet the specific needs of the digital video examiner and analyst.

Students will learn proper methods to interrogate digital video evidence while receiving guided instruction throughout the process of recovering valuable evidence from video images. The course will also focus on specialized investigative techniques for the examination of video to explore issues relating to the use of force, speed estimation and identification. A variety of DVR, body-worn and in-car video sources will be examined in depth, testing data acquisition, file identification, image accuracy, video processing work flows and report writing.

CCTV Analysis and Court Presentation Material

Train CCTVCCTV Analysis

Following an Affray at a railway station CCTV images from the station and an on board train system were used by the prosecution in the form of a DVD compilation. We were instructed by one of the defence teams to analyse the CCTV evidence and clarify images containing their client for presentation in court.

Having viewed the DVD compilation disclosed to the defence we identified that the original Digital CCTV images had been converted to the DVD format. This can introduce artefacts, reduce edge detail and sometimes even miss out recorded frames. (see more here and here) so we advised that a copy of the original material should be requested so that we could carry out our analysis on the best evidence.

We identified that the timestamp used by both systems was not synchronised which made relating what could be seen from each system difficult and possibly misleading and produced material to identify the difference.  We produced clarified video and a document containing all of the relevant video images as stills in pdf format with the position of their client highlighted.

“At one stage in the proceedings, it [the pdf document] was referred to as the ‘bible’.”


After the completion of the trial the instructing solicitor said;
“The stills were very useful in terms of the on board footage and both other defence counsel said that this allowed them to explore points which they would otherwise not have been able to. At one stage in the proceedings, it [the pdf document] was referred to as the ‘bible’. Thank you as ever for your sterling work – and turnaround. I know that I always find the way in which the material is sent very useful and easy to access / use in terms of presentation (despite my lack of computer know how). Thanks again for your hard work!”

Commendation for Video Analysis and Court Presentation

I attended a commendation ceremony a few months ago at Bedfordshire Police HQ for police officers and others who brought the perpetrators of a large scale Cash for Crash operation to justice.

The text of the Chief Constable’s commendation included the following textDavid Thorne receiving commendation for video analysis

Judge Kay said, I want to commend the diligence and professionalism of the police officers and others involved in this inquiry. It has been a long and tortuous process to piece together the web of fraud in this operation. There were tens of thousands of documents that had to be reviewed, assessed and evaluated. By their efforts, the police and others involved have brought to an end a fraud which would have continued for some considerable time after November 2006 if it had not been stopped. It would have led to further considerable losses for the motor insurance industry and, ultimately, for all of us.

I COMMEND David Thorne who went to enormous efforts to put together all the photographic and video evidence, which was invaluable as it was so important to the investigation.


David Farrell QC  previously wrote;

David Thorne worked in collaboration with the OIC and Counsel. As Leading Counsel for the Prosecution I was impressed with the skills and dedication of David Thorne. He was often required to change or amend presentations over night or even at Court. He did so with speed and accuracy. (Tweet this)

Furthermore, he made positive contributions to the operation, using his former Police investigative skills to review the photographic evidence in the context of his knowledge of the case and thereby provide in itself valuable evidence. For example, he was able to see photographic damage to vehicles the significance of which had not been apparent to the investigative team and when placed before the Jury substantially contributed to the strength of this Prosecution.

I have no hesitation in recommending David Thorne as a dedicated and skilled forensic multimedia analyst who provides a first class service.
