One of Amped FIVE‘s many input features is having the ability to preview and capture a video signal, directly within the interface.
Any Directshow compatible video device can be used. When selected, the Input Filter settings dialogue box will open, giving you the ability to choose the device and configure its settings.
Although no longer near the top of acquisition options, screen capturing is one of those tasks that when it is needed, it pays to have prepared your capture environment beforehand.
Screen capturing is fraught with difficulties. The main issue now, from a forensic image analysis point of view, is that many players change the encoded data for their display purposes. This can severely affect the video’s ability to be analyzed correctly for restoration or enhancement. As a result, relying on that captured video may be unwise in certain circumstances.
I have written about this effect, and its most common cause in CCTV, many times but I think it’s necessary to take a closer look.
To start with, this is a great little video showing the effect in action….
The two pieces of mesh have the same grid pattern. As the top piece is moved, a pattern appears. This is the Moire.
I see this daily in CCTV Images that have been obtained by taking either a single image, or a video, directly from a television or monitor screen.
OK, sometimes this is required. The immediate publication of some form of imagery is often an ideal way to obtain recognition intelligence at an early stage. Especially if the native, evidential acquisition of the visual material would delay this process.
The evidence can be recovered correctly later, and further images publicized at a later time.
Let’s now look at this image loaded into Amped FIVE… Continue reading
Doing the same thing to a number of files is as simple as Copy & Paste!
It’s a simple function, but one that can dramatically speed up the processing of files in Amped FIVE. It also ensures that any configurable settings are ‘copied’ exactly. No need to write down or screenshot settings – just copy the filter!
In this example, I have three .dav files that I need to process. After dragging the first one into FIVE, the Direct Play dialogue box appears. As these are proprietary streams, they need preparing first as they have no header or index.
Everyone has a mobile phone …
A crime has occurred. What’s the first thing that people around the scene do? They grab their mobile phones. Why? To call the police or emergency services? Not usually. Not at first.
First things first.
They want to go viral on social media.
But it’s dark, and the person holding the phone is excited and moving around.
They capture the events and eventually send it to you. But it seems worthless. How can you make sense of this dark, shaking, video?
It’s been a busy 6 Months!
Receiving dedicated training in our software is one of the first things that new purchasers put in place. Very often, this is taken into consideration when making the initial order.
The simplicity of installation, management and updating makes the Amped Software portfolio of products an easy solution to the challenge of Multimedia Forensics. On a personal level, it gives me so much enjoyment to help new users get to grips with the software and watch their early first steps.
Amped FIVE Training in South Africa
After the attacks of Paris, Brussels (and unfortunately many others), three days ago there was another major event at Istanbul Airport. While its origin is yet to be officially confirmed, strong hints are again at ISIS terror strategy. The number of victims is currently set at more than 40 and growing, with more than 160 persons injured. This is, again and again, a very sad story and our prayers are with the victims, the wounded and their family.
As usual, in these major events, it is interesting to analyze the different audio and video sources and their use. Continue reading
On the 27th July F3 are hosting one of their annual UK workshops, this time, dedicated to Forensic Video Analysis.
The workshop will be conducted by me, David Spreadborough, the International Trainer here at Amped Software.
I will be covering topics such as:
- Video Surveillance Systems, Storage, and Evidential Acquisition
- Multimedia Analysis
- Multimedia processing
- Image and Video Enhancement
It is at the Dunchurch Park Hotel & Conference Centre, Warwickshire, UK
For more information, contact the F3 Secretary Lindy Sheppard by using the Contact Page HERE.
I am very excited to announce that next week I’ll be at the ACM Workshop on Information Hiding and Multimedia Security, in Vigo, Spain from June 20 to 22, 2016.
Why am I so excited? While I love visiting customers, going to trade shows and partner events, this is a purely scientific conference. Our roots are in the academic world, and we are still cooperating with different universities and research institutions very often. And this time, I have the honor of giving a keynote in front of some of the world most well-known researcher in our discipline.
The title of the presentation is “Bringing Multimedia Security from the Research Lab to the Forensic Lab”. This is the abstract of the presentation: Continue reading
It’s Amped FIVE update time again!
With so much to get through, let’s start with some new and exciting filters. Not one, not two….. but six new filters in the Adjust Category. Yes – Six new filters designed specifically to restore color or illumination to an image, and improving those taken with High Dynamic Range.
This filter gives you very precise control over the four portions of the luminance range. As you adjust the sliders, the curve will move accordingly, and a shaded area will appear in the Curve graphic. This will show you the maximum or minimum adjustment available.
