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!
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!
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!
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!
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.
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.
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!
Dear friends, welcome to this week’s tip! Today we’re sharing a tip to make the most of the Perspective Super Resolution filter recently introduced in our Amped FIVE. Right from its release, it’s one of the filters our users love the most, thanks to its ability to automatically track and align license plates even under strong perspective variations! But, you know, here at Amped we’re not happy to provide you with just nice results. We want to give you excellence! So, today’s tip is about further improving the image produced by Perspective Super Resolution… keep reading to find out more!
Dear Amped blog friends, welcome to this special tip on Tuesday, Dec. 24! Today we have a very special request, actually, we have a mission. If we succeed, someone will be happy tonight. If we fail, someone will be disappointed. Keep reading to walk with us on this adventure!
Dear Amped friends, welcome to this week’s tip! Today we’re showing you a pretty sci-fi feature available in our flagship solution, Amped FIVE: the Fourier filter, allowing you to remove periodic nuisances from images and videos. It’s a very effective way to gain a better view of the object of interest even starting from critical conditions. If you’re now curious, or if you didn’t understand one single word of what you’ve read until now… just keep reading and everything will be clarified!
