Amped FIVE Update 11284: Multiplexed Stream Support, Proprietary Timestamp, Remove Frames Filter, and a Whole Lot More

Whilst it’s been a busy time for us here at Amped with the demand for training higher than ever, we have made sure our development is continuous and we’re here again with another huge update for Amped FIVE.

A Completely Revamped Conversion Engine

As you will know, one of the biggest struggles within the world of CCTV and video analysis is the ever-increasing number of proprietary formats. Our support and development team are constantly receiving requests for new format support and in our latest update, we have enabled conversion support for BVR, DVS, H64, PSF and SHV formats, along with some variations of other formats already supported in previous versions.

All these formats are multiplexed streams. This is when a manufacturer has placed all camera footage into a single time-based video stream.

The latest FIVE not only converts the files straight away, but demultiplexes each video stream, splitting them into their own individual chains within the software. Under the Convert DVR Advanced tab you will find the options to enable this time-saving function.

Files to Convert > All, one chain per file.

No more mixed streams, no more time wasted writing carving scripts. A few clicks will now save you hours!

Multiplexed single stream decoding is huge, so expect a dedicated blog post in the next few weeks looking more deeply into decoding files of this type.

But the new conversion engine does not stop there! There are a lot of benefits even on single stream video files. Standard conversion done with vanilla FFmpeg is often not enough – there may be the risk of losing video frames because of wrongly interpreted proprietary metadata. Our new engine not only cleans almost every proprietary video format, being in MPEG4, H263, H264 and H265, but for many of them also recovers the proprietary timestamp. We found more than 50 different variations of timestamp formats!

Video Redaction with Amped FIVE

First of all, let me introduce myself. I’m Lucy Carey-Shields, the newest member of the Amped team! Originally from the UK I studied Computer Forensics at degree level and was a volunteer police officer with a UK police force for six years. I later went on to work for another UK police force for almost four years as a digital forensics technician, mostly working with CCTV and video whilst also providing forensic acquisition of mobile devices. Whilst working at Amped I’ll be providing support as well as putting the software through its paces, so I look forward to hearing from you all! Now let’s dive into my first Amped blog post! 


When dealing with video, we often have to hide sensitive information or protect a person’s identity, particularly if the video is to be shared with a wider audience and we need to control the display of certain information. Amped FIVE has a filter for that!

Having used two or more different tools to load, process and then redact sensitive footage in the past, I know how time-saving having all these features in one piece of software can be (and how critical time can be in a law enforcement environment).

The Hide Selection filter allows you to pixelate, blur or blacken anything you want masked in a video quickly. In this instance, we’ll explore both dynamic tracking and manual tracking during the use of Hide Selection. Hide Selection can be found under the Presentation group of filters, typically used at the end of a workflow.

Redaction, whilst usually done towards the end of processing a video, is arguably one of the more critical steps in a workflow as revealing sensitive data or someone’s identity could have serious and potentially dangerous consequences. With this in mind, it’s important we ensure frame by frame accuracy so that the subjects we want to censor are completely disguised. FIVE allows you to apply the filter by selecting the necessary points – maintaining that important frame by frame accuracy. Continue reading
