DVRConv Update 11571: Multiplexed streams, timestamp extraction and more formats now supported

We’ve released another update for Amped DVRConv, one of the fastest ways to cleanly convert video. It is also the simplest; a clean installation tool that allows anyone who works with digital video to drag and drop proprietary video evidence in order to achieve a standard playable file – cutting out the hours, or even days, it takes to locate a proprietary player. Drag and drop – it’s that easy! With DVRConv, alongside Amped FIVE and Amped Authenticate, your workflow from scene to laboratory is completely covered and together they provide great weapons in your forensic video and image analysis arsenal!

Let’s say you regularly process video evidence and, like a lot of technicians and analysts, you are tasked with retrieving video from a scene at a location other than your lab or office. Retrieving CCTV from DVRs at scene can often be laborious, fraught with difficulty and a lot of the time the scenes are a fair distance away from your usual office. One of the most important steps during the recovery of CCTV evidence is checking to see if the download has been successful, which means playback of what is more likely to be proprietary video at scene using only a laptop and your recovery tools.

Saving time at a video recovery scene is crucial and it’s a nightmare having to trawl through hundreds of proprietary players, some of which won’t work on your current operating system or might have different versions of the same type of player. The conversion engine in Amped FIVE would be ideal, but you want something more portable to add to the tools on your retrieval laptop. This is where DVRConv steps in to quickly convert and playback your downloaded files in an easily customisable and cleanly installed package!

Utilising exactly the same conversion engine as FIVE but with twice the portability, you can not only playback and confirm your video files at scene, but have them ready for clarification and enhancement in FIVE for when you return to the office or lab.  Logs are provided for disclosure and the original files are left untouched, maintaining the continuity of your video evidence from the beginning.

Content Triage

Here in the US, we’re hyper-focused on standards and compliance. In the aftermath of the 2009 paper, Strengthening Forensic Science in the United States: A Path Forward, many national and state initiatives were put forward to address the issues raised in the document.

We love checklists. Yes, sometimes there’s a need to stray a bit from the workflow, but checklists help guide the work.

In our classes here, we present the workflow from the standpoint of science and the law. One of the most important steps in the beginning of the workflow is Content Triage.

Content Triage is the process of asking of one’s digital multimedia evidence, “do I have the appropriate quantity/quality of data to answer the questions in my case?”

If you do, great. Proceed with your work. If not, your results will be limited and those limitations should be noted in your report. An example of a limitation can be seen in the many files processed where the target area lacks sufficient resolution.

I’ve got a short video on this topic over on our YouTube page (click here).

I’ve been traveling the country speaking on this topic and its importance in investigations. My next stop will be at the Society for Integrity in Force Investigation and Reporting Annual Conference in Henderson, Nevada. You can get more info on this event over on our Events page. I hope to see you there.
