Amped FIVE Direct Preview from DVR Examiner

Direct Preview in Amped FIVE from the DVR HDD Application, DVR Examiner, now means a seamless workflow between the two products.

Native data recovery from DVR HDD’s can be a tricky business. DVR Examiner, by DME Forensics, can take a lot of this pain away.

When viewing a directly attached (write blocked) HDD, or a forensic disk image, if the file system is supported, all the clips will be viewable.

Right clicking a clip brings up various options. Under Preview With.. you will now see Amped FIVE as a choice.

Video Input

One of Amped FIVE‘s many input features is having the ability to preview and capture a video signal, directly within the interface.

DVR Screen Capture

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.

The Moire Effect

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 FIVEImage 4 Continue reading

Chains & Filters – Using the Copy/Paste

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.

Amped Training Review

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 Update 8222 – Adjustment Filters, Program Options and Much, Much More!

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.

Parametric Curves

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.

Understanding Differences

Using the differences between images is a powerful technique to assist in processing and analysis within Amped FIVE.

There are many ways that the differences in images can be used. The first one, and probably the most common, is to remove duplicates. Understanding how the Remove Duplicates filter works is important, as it opens up other possibilities that may not be immediately obvious!

Here we have a pretty standard looking H264 Video inside the .mp4 container. Once loaded, certain information starts to raise questions.

The Report – “It speaks for itself”

The creation of the Forensic Report from within Amped FIVE may only take a few mouse clicks, but it is an extremely powerful feature.

A high percentage of Forensic Video work revolves around the analysis, the processing and the output of a new exhibit. That could be a single image, a series of images or a new video.

You may need to redact certain parts or enhance others.

As a result, it important to document that you received A, you did B, and you produced C.

When using multiple open-source, freeware or consumer tools, the documenting and reporting of all the software and processes can take a long time to complete. There are also difficulties when validating the movement of files between one piece of software and another.

A recent case involving an integrated player/video executable highlighted the ease, and speed, of report generation that is available to FIVE’s users.
