What’s in a name? How to rename in Amped FIVE

I’ve been on the road a lot lately. By the end of this month, I’ll have spent two weeks with District Attorney’s Offices in New Jersey (US) training users in the many uses of Amped’s flagship product, Amped FIVE. Every user has a slightly different use case and needs. Prosecutors’ Offices are no different.

Field personnel / crime scene technicians / analysts might not be very concerned with trail prep and the creation of demonstratives for court. But, DA’s offices are. That being said, there are a few things that every user of Amped FIVE can do – beginning with the end in mind – to make the trial prep job a bit easier.

Hopefully, by now you know that you can rename processing chains in Amped FIVE to aid in your organization.

Right click on the Chain and select Rename Chain. Then, name it something unique that describes what you’re working with or the question you’re trying to answer in the file. Examples include camera number, vehicle determination, license plate determination, etc.

This is quite helpful. But, did you know that you can also rename the Bookmarks? Additionally, you can add a description to the bookmark. Let’s see what this looks like.

Using Project Files as Templates in Amped FIVE

People often ask, “How can we speed up the processing of files in Amped FIVE ?” (As if it’s not fast enough :). “Can we create actions/templates?” The answer is yes. Here’s how.

Load a video file. In this case, we’ll load a BWC file from an Axon Body 2 camera.

Then, we’ll rename the processing chain. Right mouse click on the processing chain – Rename Chain.

The Beginner’s Guide to Suspect Height Calculation from CCTV

Otherwise known as ‘The Science of Single View Metrology’

The first common question asked to a forensic video analyst is, “Can you tell me what that license plate is?”. The second question is, “What is the height of that person?”.

It is then the forensic video analyst’s responsibility to analyze the video, assess its suitability to answer the question, process and prepare the images, and then finally use science to provide the answer, based on facts.

Taking a ‘workflow’ approach can often safeguard the user from missing vital information that may be relevant further along in the process.

There are a few different methods to attempt an answer to this height question, with different constraints, reliability, and drawbacks. In this post I will be taking an in-depth look at the technique built into Amped FIVE, using the filter Measure 3d.

What’s wrong with this video?

What’s wrong with this video? Hint: look at the Inspector’s results for width / height.

Unfortunately, the answer in many people’s minds is …. nothing. I can’t begin to count the number of videos and images in BOLOs that attempt to depict a scene that looks quite like the one above. If you don’t know what you’re looking at, it’s hard to say what’s actually wrong with this video.

The Temperature Tint Filter

We’re back from the Axon Accelerate Conference. What an incredible experience to meet so many law enforcement professionals who are enthusiastic about going from Capture to the Courtroom with reliable tools based in science and fact, not tools repurposed from the art world.

I’d like to share today the answer to a question posed to us at the Conference. The question was, “how do you quickly get rid of that annoying orange color cast that you find in images / videos taken in underground locations or grow houses.”

The answer is the Temperature Tint filter (found in the Adjust filter group). But, before we look at the filter and how it works, let’s talk about about Colour Temperature.

The chart above is from my old book, Forensic Photoshop. It’s helpful to look at colour temperature from the standpoint of the Sun as it rises – the horizon going from warm to cool. Another way to look at colour temperature is with the chart below that places temperature (the Planckian locus in Kelvin) as it relates to the CIE XYZ Color Space.

The Flexibility of the Add Text Filter

If you’ve wondered at the filters in the Extract Filter group and asked yourself, what are these for, you’re not alone. Depending on your specific use case with Amped FIVE, there are likely a few filters for which you have no use in your current context. Others, you may use in a very specific way each time – but others may use them differently.

Thus it is that I encountered a request for a feature that’s been in Amped FIVE for quite some time. I’ve responded to the request with details on how to accomplish the task. Now, I’ll expand on the question and share a more detailed look at an often overlooked filter – Add Text. (click on the images to see the full-res versions)

Working with Subtitles in Amped FIVE

Law enforcement officials have been sending out recordings of interviews to transcription services (or in-house transcribers) for decades. A complete and accurate text file of statements made in suspect / witness interviews has been a valuable aid to Detectives and Attorneys alike. Now that agencies have implemented new recording technologies (Body Worn Cameras, In-Car Video, & Interview Room recorders as examples), LEOs are looking to have the recordings made by these devices transcribed as well.

There are many services out there offering transcription for law enforcement. When choosing a service (when sending sensitive information outside of the LE agency), important considerations come into play. Not the least of these considerations are information security (CJIS) and standards compliance. There are plenty of services out there offering security and speed – both of which come at a cost. The most important consideration, however, is the format of the deliverable file. If the text is going to be used as subtitles for a video, it has to be formatted in a specific way. To be used as a subtitle file, It has to be formatted as a subtitle file. Not all transcription services offer this service. So it’s vitally important to choose a vendor that supports transcription that includes timing information and can produce a subtitle file. Without the timing information, synchronization of the text to the video becomes a manual (time consuming) process. With the timing information (see below), it’s fast and easy.

The good news is, we’ve got you covered. In fact, we’ve been supporting the insertion of subtitles for years. Let’s take a look at how this is done.

Amped DVRConv: The Beginner’s Guide

Simplicity, speed, and forensic integrity all come together in Amped’s latest software, providing law enforcement and digital forensic labs with a quick and easy stand-alone solution to the challenge of video conversion.

It’s been a few months since its release, so hopefully by now, you will have seen the blog posts and press releases regarding Amped DVRConv. It is a very easy program to use…it really is. You tell the application that you have a video file that you cannot play, the software analyzes the file and format, and then it gives you a video file that you can play in any standard playback software, along with the conversion log for full disclosure.

How do you tell it? That’s easy as well. You either use drag and drop, copy and paste, or even have it ‘watch’ a specific folder and then convert immediately.
