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.

Can you see in the dark?

A crime has occurred. Your investigators comb the area looking for clues. Your media relations staff hit the airwaves asking for the public’s help. Your social media cyber team trolls the Internet for images taken about the time of the crime and in the general location.

Bingo!

An image shows up on social media that was taken a few minutes before the crime occurred, looking down the street at what is now your crime scene. But, what’s wrong with this picture?

Taken into the setting sun, the features of the scene are back-lit. Useful information is lost.

Or is it? Continue reading

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.

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.

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.

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.
