The holiday season is fast approaching and what better way to celebrate than with another Amped DVRConv update!
We’ve added even more parameters to the Program Options menu – let’s take a look!
Dear friends, welcome to this Tip Tuesday! It’s a rather anomalous one, indeed, since we’ll not show any trick about using a specific Amped solution as usual. But we’ll still provide you with a very good tip: we’ll guide you through some of the freely available datasets you can find online, that you can use to test and validate our Amped FIVE, Amped Authenticate, Amped Replay, and Amped DVRConv. Yes, you’ve read correctly! There is lots of data out there that you can use to make your own experiments and increase your confidence in our software reliability. Keep reading to find out.Continue reading
We’re here with another update for Amped DVRConv, one of the fastest ways to cleanly convert multiple video files.
Amped DVRConv remains one of the top go-to tools for practitioners who need to convert video quickly, cleanly and easily. It’s my first choice when I have a large amount of video files that I need playable – I simply drag and drop my files into Amped DVRConv and it does the work for me in the background, while I am free to work on other processing!
It’s also great if you are out in the field and need to convert video on the go, ready for when you return to the lab for input into Amped FIVE or to pass onto colleagues or other agencies. The great thing is, the original files are always preserved and log files created with each conversion, meaning your original video evidence is always kept secure.
We know how many different standard and proprietary video formats are out there and how frustrating it can be to come across a new format that you just can’t seem to do anything with.
For this reason, we are constantly working to add support for more formats that you send to us and in this update, we’ve done just that!
Some of the new simplicities afforded to us can, unfortunately, cloud ones’ judgement when dealing with images and video for legal use.
Technology has, in most parts, made things incredibly easy. Take the example of photographs and video. We all now love to quickly snap a memory or record some footage of an event. We can adjust the

In late 2016, at the conclusion of a trial in Nottingham Crown Court, for four men involved in the murder of Aqib Mazhar, Judge Rafferty stated, “there must never be another case in this country where those analysing CCTV don’t have the best equipment.” The quote stems from the fact that it wasn’t until the trial had started that video material was properly reviewed and that significantly changed the weight of the evidence.
Whether it is CCTV evidence, mobile phone video or a sequence of images, the software used to review that evidence can alter the viewer’s interpretation. It could be that the player drops or misses frames. The player could present the video too dark, or too light. The player could change the shape and size of the image or video, resulting in objects appearing smaller or larger. Many surveillance system players alter the image to make it look better, even though that is not what was originally recorded – scary, but true.
In 2015, a conviction of Indecent Assault was overturned at the Court of Appeal.
Multimedia evidence, especially CCTV or low-quality mobile phone footage must be handled with care.
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.
‘Caught on CCTV’ — how many times do we read or hear those words?
With cities worldwide sitting under the gaze of millions of public and private cameras, it is no wonder that in many cases, the best chances of identifying an offender starts with the image caught on CCTV.
But, the simple task of getting an image can sometimes be a challenge so it is no wonder that people look at the shortcut and simply take a picture of the CCTV monitor with their phone. It’s quick, simple and you immediately have an image.
This is great when recognition is time critical. The image of the ‘man in the hat’, the 2016 Belgium terror suspect, was first released after a snap of a CCTV screen. Then, a few days later, the forensically acquired evidential images were released.
When something is not time critical, then the correct acquisition of the original video will help immensely in any integrity or authentication issue. Not only that, but if any restoration or enhancement is required, then you will have a much better chance of image recovery.
Faces and vehicle licence plates are often requested for recovery. They have two matching characteristics – high detail. It is these high details that are lost when a piece of CCTV is captured incorrectly, snapped from a PC screen, re-recorded with the analogue video output, or obtained any other way that changes the original digital structure.
An added problem with some of these processes is that small details can change shape and become blended together. Letters and numbers on licence plates start to look like other digits.
It can be frustrating to use multiple pieces of software with a need to ensure no loss of quality during every stage. This obviously adds extra and unnecessary time to the workflow. Time that is extremely valuable in today’s policing environment.
A by-product of using Amped FIVE, the ‘all-in-one’ solution, is that investigative decisions can be actioned much faster. “Am I going to get something from that?” If the answer is no, then it’s time to move on. Spend the time on what is achievable and negate the impossible.
Licence plates usually stay within the policing world but faces, clothing configurations, and tattoos regularly end up in the press, social media, and within online galleries for recognition.
Therefore, it’s worth taking a bit of time with these to ensure the highest possible chance of some good intelligence. It can also avoid some embarrassment – reading through public comments on a few sites makes for painful reading due to the image posted being so bad!

With CCTV probably being the number one piece of digital evidence used in cases, many officers will have asked questions like, how do I get the footage; why is it not playing; or how can I get an image? It’s important therefore to understand why we have ended up here. Why digital video, specifically from the surveillance industry, is such a huge pain in the proverbial!
As computers and digital video started to creep into normality, the surveillance companies started to think of ways to say, and prove, that they were better than the other. One of the easiest ways to do this was to use a bespoke recording method and format, to suggest that it was better than the other. This is where it starts to go pear-shaped.
Very quickly we ended up with non-standard video files, requiring a player that could not install on a Force computer, with no method to interrogate, analyze, validate or process the evidence as required by the investigation.
It has been nearly 20 years since the start of Digital Video Recorders, and you will be glad to hear that things are improving. But, it is going to take a long time for many of these poor systems to get replaced by ones that are fit for purpose.

Acquiring evidence from a digital camera or a smartphone is more or less relatively easy to do. Images are usually in standard JPEG format and videos in MP4 or some other format that most players can read. But what is the best way to retrieve and handle CCTV footage to ensure it stands up to the scrutiny in the courtroom? There are numerous possibilities and it depends on where the video is actually recorded.

Today we released an update to Amped DVRConv, the easiest way to convert videos from proprietary DVR formats.
We have been working on this update for some time and a few users have received beta updates in order to support formats that were urgently required. During this period we have re-engineered a good part of the architecture to improve stability, speed and format compatibility.
