What is the Frame Rate?

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.

Go Live! Let Your PC Be a Witness Using Amped FIVE’s Video Input to Record Everything You Do

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!

Few GBs Left? Slow Connection? Amped Replay Lets You Pick Just the Frames You Need, so You Save Data and Don’t Lose Quality!

Hello, dear Tip Tuesday people! During the COVID-19 emergency, many have to work from home. Some rely on metered connections, which makes gigabytes almost as precious as drinkable water.

So I thought I’d share an easy tip to remind you that, with Amped Replay, you can often cut the part of the video you need without re-encoding pixels (so, no quality loss!). It only takes three clicks and may save several gigabytes… keep reading to find out more!

Where Is the Rest of the Video?

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!
