Dear friends, welcome to this week’s tip! Today we continue the mini-series about Amped FIVE‘s Video Input filter. We’ll see that it can be your greatest ally when you’re dealing with reverse projection, that is, when you go to the crime scene to place a height chart or some other reference element. In these cases, the Video Input can save you a lot of time and headaches! Keep reading to find out more.Continue reading
This follows on very nicely from my previous post, ‘Where Is the Rest of the Video?’, where we had to analyze video metadata in order to answer questions about missing footage. In the case here, we have some discrepancies with the frame rate. Let us take a closer look.
The first thing to point out is that I have recently changed one of the Amped FIVE Program Options and I thought it was worthy of an initial mention.
I am coming across many more CCTV files with audio streams. Now, I am not saying that they all have noise, but they do have a stream. As such, I have changed my video engine default to FFMS with Audio.
This engine is now the default on new installations. However, if you have updated from a previous version, the old settings are retained.
Upon loading the video into Amped FIVE, I can see from the File Info tool that an audio stream has been detected, but the waveform envelope in the Player bar is empty.Continue reading
Dear Tip Tuesday maniacs welcome to a brand new tip! Actually, we’re beginning a mini-series of tips, dedicated to an often overlooked feature of Amped FIVE, the Video Input filter. It lets you get a live video stream from an input device and process it “on the fly” with Amped FIVE filters, or record it to a file. There are three major video forensics applications that can greatly benefit from this filter: 1) documenting the acquisition from a DVR, 2) reverse projection, 3) live processing of frames. Today we introduce the filter and deal with point 1, while the rest will be addressed in the future. Keep reading to discover more!Continue reading
Video investigators often receive files with little or no information surrounding the source, acquisition or handling. The files are often created by people with little knowledge of the legal requirements of data type and continuity. These issues, and quite a few others, all impact on the initial investigation as discrepancies can cause major problems further along in a case.
Let’s look at this file for example…
All images with sensitive data have been redacted.
Upon viewing in Windows, the thumbnail and extension are shown, and hovering over the thumbnail reveals further information.
I am being told that it’s a Windows Media Video, it’s just under 4Gb and has a length of just under 27hrs.
The CCTV request for footage did detail a time duration of 27hrs so it all looks good so far.
As the title of this blog post is, “Where Is the Rest of the Video?”, you just know that things are going to go wrong!Continue reading
Dear friends welcome to this week’s tip! Since the latest Amped FIVE release, users can deal with audio much better than before. Today, we’re demonstrating that in some cases you can effectively use the audio waveform as a guide to synch in time two video tracks. Keep reading to find out more!Continue reading
Dear Tip Tuesday maniacs welcome to this week’s tip. We’re receiving a lot of positive feedback from users who tried the latest Amped FIVE release! Thank you so much for finding the time to send us your opinion. The new audio support is definitely the most welcomed improvement, so, on the wave of that, we’re dedicating this week’s tip to show how you can redact audio in Amped FIVE, with a walk-through example to try this new feature on!Continue reading
Welcome back, dear Tip Tuesday mates! Today I will be showing an Amped FIVE feature that I’m pretty sure most of you have never tried before… because it’s so new! Since the latest release, Amped FIVE integrates audio track viewing and redaction capabilities. Why don’t you take your first walk through this functionality with this tip? Ready? Let’s go, then!Continue reading
Hi all, it’s been a while! I’ve missed you!!
I am currently going through the last few years of Amped FIVE training and it has highlighted several useful points that I want to pass on. All the points can get wrapped up neatly under one word: Workflow! And where does this get used the most? In our Amped FIVE projects.
A workflow is a repeatable pattern of activity and processes through which work passes from initiation to completion. Having workflows is a core requirement of any Forensic Image and Video Unit (FVIU), ensuring that the quality of work is maintained through standard operating procedures. The challenge for FVIUs, though, is that they are starting with a non-standard product; with every case, video and frame being different. Therefore, any workflow set for a technician or analyst must be dynamic, placing the importance on their competency to select the right tool, method and/or process to complete the objective.
Let us say that two analysts are requested to complete the same tasks – to locate a vehicle in CCTV footage, enhance the license plate and then create a small video clip for use within a legal system.
Analyst No.1 starts by copying the data from a media exhibit and then uses the tool they know best to quickly screen capture the video within its dedicated video playback software. This creates a new ‘working’ video file. This can be imported easily into the court presentation software, which creates another file for presentation. The analyst uses the working file to create several still images. They do this by utilizing another piece of software, and then they import those still images into image editing software. Attempts are made to conduct restoration and enhancement but with no success.
Analyst No.1 has used six different pieces of software and has created several files, that will all need to be saved and documented. Although they have completed the tasks, the workflow is complicated, the integrity of the exhibits could be questioned, and the processes used have caused a loss in the visual information that resulted in the enhancement being unsuccessful.
How about analyst No.2?
They use Amped FIVE (of course). With FIVE’s ability to control everything from ingest, through file analysis and into the restoration process, a trained user is much more likely to avoid many workflow problems and get the results they require.Continue reading
Dear Amped blog habitués, welcome to this week’s tip! In Italy, we have a saying that goes like this: “Anche l’occhio vuole la sua parte”. It basically means that “you should also please the eye”, as a way to say that the outer aspect of something is, all in all, pretty important. Translated for the forensic image and video enhancement world, it means you should invest in presenting your results, otherwise, even a brilliant piece of work could remain unexpressed. This tip shows how to annotate the results obtained in Amped FIVE with text macros, adding a lot to the usability and professional-feeling of your videos.Continue reading
Dear Amped blog followers welcome to this week’s tip! Today we’re getting to know a very useful, but often underestimated, filter in Amped FIVE: the Perspective Aligner. It can be a game changer when you have to integrate or compare two pictures that are captured from different perspectives, and thus impossible to align with simple scale/rotation transformations. We’ll see how it works with a practical, cool example… keep reading!Continue reading
