Zoom In On That! Amped Replay’s Magnify Tool Creates Impressive Magnifications That Boost Your Evidence Effectiveness

Ciao Tip Tuesday friends! This week we have a special surprise: we are pleased to dedicate the first Tip to our newest product Amped Replay. Replay is an enhanced video player designed to help even nontechnical users in their daily work with forensic images and videos. It covers the acquisition, triage, essential enhancement, redaction, annotation, and exporting phases. All of that served with Amped’s special seasoning, that is, forensic soundness. For a full product presentation, just visit this page, or watch this video. Today, we’re focusing on a great feature in Amped Replay: the Magnify annotation tool, which lets you create compelling and attractive zooms of selected areas in your frame.

Let’s imagine a case where a robbery takes place in a chemical factory, and the offenders drive away in a car. The stolen material could be easily weaponized. The ability to readily send out a video to the media showing the vehicle means that you can turn all citizens into patrols looking for the criminals’ car. But you need to do it quickly, in minutes.

The closest police patrol arrives on scene and the officers head to the CCTV recorder and grab a video showing the offenders’ vehicle. The officers get their laptop out, fire up Amped Replay, and the video is ready for inspection. The suspects’ vehicle is quite visible, as shown below:

In a Flash, with the Hash! Learn How to Quickly Spot Identical Frames in Amped FIVE

Ciao dear Tip Tuesday friends! Have you ever noticed that, somewhat surprisingly, it is much easier to see that two things are different rather than the same?

Now, if you’re facing eight million pixels, that could take a while! That’s why Amped FIVE helps you to see whether two frames are exact duplicates in a second! Keep reading to learn how…

Scripta Manent: Learn How to Quickly Lay Out and Print to Paper Many Frames With Amped FIVE

Welcome, Tip Tuesday lovers! Despite being close to the year 2020, it is still quite common to meet people that refuse technology. This is especially frustrating in the judicial system, where the backlog is never-ending, and technology would surely help. Sometimes, you may be asked to provide “printed” frames of your video. Not just a couple of significant ones (that would still be reasonable): no, many of them. Will Amped FIVE ease your pain this time as well? Yes, of course. Keep reading to find out how.

Amped FIVE Filter Order: It’s Better to Get it Right!

If you have attended an Amped FIVE training (if you haven’t yet, here is the list of upcoming classes), then you know how much stress we put on the “correct order of filters.” The footage you’re working with is the product of a long acquisition and processing chain, which usually introduced several artifacts. The most reasonable way to go is to compensate for these artifacts in the reverse order. If you like math, here you can find some reasons supporting this choice, which is also summarized by the drawing below. As you can see, if going from X to Z involves passing first through f and then through g, then going back from Z to X requires going through the inverse of g first, and then the inverse of f.

If you’re more on the practical side, it’s still quite intuitive: if you first put on your socks and then your shoes, you’ll have to take off the shoes first and then the socks. In this trivial example, “take off” is the inverse function of “put on”, and it is evident that you need to take off clothes in the reverse order of how you put them on!

Sharing the Smoking Gun: Did You Know Amped Authenticate’s Camera Identification Can Work With Images From Facebook?

Dear Tip Tuesday fans, welcome! This week’s Tip is dedicated to showing the power of the widely loved Amped Authenticate‘s Camera Identification filter. Based on sensor pattern noise analysis, this filter is one of the most reliable and robust in the image forensics field, where “robust” means it may still work even after the image has gone through significant processing. To demonstrate this in practice, we’ll see how the Camera Identification filter often works even on images downloaded from Facebook, which has a dramatic impact in terms of applications.

Need to Process a Lot of Images But Time Is Short? Don’t Worry! Amped Authenticate Runs a Custom Set of Filters Offline and Caches Results For You

Hi, dear Amped blog readers, welcome to this week’s Tip Tuesday! As you surely know, Amped Authenticate is the most complete image authentication suite on the market. It has so many filters… and sometimes they could be too many! Today we’re going to see how you can save time by using Batch Processing and customizing the filter configurations.

Saving time for our users is one of Amped’s main goals. We know that every day you’re dealing with a lot of casework and investigations, so we constantly strive to make our products intuitive to use, fast, and configurable. Unfortunately, there are some things that take time by their nature, and this is especially true for some of Amped Authenticate’s Local Analysis filters. The Clones Blocks, to cite the worst case, can take several minutes to run on a single image, because it has to compute millions of descriptors and match them.

Of course, we don’t like the idea of making you sit in front of the monitor waiting for a filter to complete. That’s why Authenticate features the result caching system: once a filter is computed for an image, the result is stored and will be loaded the next time you click on the filter. This functionality works great when combined with another one, the Batch Processing (available under the Tools menu).
