A series of Key frames (K) and Delta frames from a video stream.

Lossless trimming is the ability to trim, cut or extract segments of audio & video without re-encoding the original multimedia streams, maintaining both the original frames/samples and their related metadata. It is a process as old as digital video itself, and one that can be extremely helpful when dealing with hundreds or thousands of hours of digital video evidence for a case.

Reduce file size, reduce duration and maintain the original frames & quality. Bonus, the process is even faster than traditional editing, as you don't have to wait for the video to be re-encoded!

Spatial vs. Temporal Compression

Spatial (Intraframe) compression is applied to each video frame independently, treating each frame as a stand-alone image. This is the type of compression leveraged by high-end video production facilities as it provides superior picture quality and efficiencies in the editing process. Every frame is a key frame.

The director of the FBI used his keynote address at the RSA 2010 conference to appeal for greater co-operation between law enforcement and the private sector to tackle online crime.

Robert Mueller told delegates that the need for co-operation had never been stronger, as online fraud rises to huge levels and the next generation of terrorists move online in unprecedented numbers."

I'm just back from a week of vacation, all of which was literally spent moving into our new home...a block and half away. Ugh, what a process. With that behind us now, I'm excited to get back to work on the DME Resources online training library!

I will be completing the Navigating & Using DME Resources training course over the 4th of July weekend, and we're still on schedule to launch the first DME related courses prior to the end of summer.

If you or your agency have a DME related topic or tool that you'd like additional training on, shoot me a note and I'll see if I may be able to help (or at least put you in touch with someone who can). Thanks for your continued participation and interest. Have a great 4th of July weekend everyone, be safe!

A few weeks ago, I was on the March Networks site to download their T263 codec to share with a colleague and cross reference with the version on Media-Geek.com.  I was back on their site again today briefly because of another inquiry from a colleague about this codec and noticed that their related support page had been updated to include additional versions of their codec, descriptions on which models of their recorders relate to each version, and separate download links for their proprietary software as well.  Here's the direct link:

Please know I am not affiliated with March Networks in any way nor am I attempting to advertise for them.  I was simply impressed with the recent update on their site that included this additional detail and thought you may find it helpful.  Wouldn't it be great if all DVR/NVR manufacturers included this much information on their support pages?  Never mind, no need to answer that. 😎

Digital video evidence is coming at law enforcement agencies hard and fast, and both the pace and quantity of digital video evidence continue to increase exponentially. There are so many digital video sources, each with unique challenges and issues when it comes to proper evidence collection, viewing, interpreting, presentation and management of the evidence. Training is critical for all of those involved in the entire chain of evidence, especially in a field or discipline that is constantly changing and evolving.

If you’re involved in the digital video evidence chain, below are a few training events that I’ll be at next month that you may find interesting. Hope to see you there!

May 13-15, DVR Assessment & Video Recovery, Burtonsville, MD

May 19-23, LEVA Level 1 – Forensic Video Analysis & The Law – University of Indianapolis, IN
