There is more Digital & Multimedia Evidence (DME) than any other type of evidence today.
Working together we've expedited tens of thousands of criminal investigations. Learn more
Premiere Pro has already been tearing through video with OpenCL on Macs for a year, and now AMD and Adobe have teamed up to bring support for the open standard to Windows with the software's next version.
Encryption is all the rage, again. Politicians and government officials apparently have no problem with using fear mongering to conjure up support for backdoors to encrypted devices and data. Privacy advocates keep doing the same, basically, warning that providing big brother with backdoor access to encrypted data is like leaving the cookie jar in your wide-open kitchen window, on Sesame Street.

One of the tools many of us keep in the toolbox for recovering from CD/DVD was recently updated to support other types of media, to include removable drives and hard disks. It's also added support for NTFS. Not familiar with IsoBuster? Check it out at www.isobuster.com
On vacation, but thought I'd comment on this topic before getting on the Harley to go run some errands in the cold Pacific Northwest. As pointed out in someone else's recent blog post, MPEG-4 can leverage what is referred to as a Sample Aspect Ratio (SAR)...not to be confused with Storage Aspect Ratio (SAR) or Signal Aspect Ratio (SAR). It's important to note that in the case of MPEG-4, the Sample Aspect Ratio is the Pixel Aspect Ratio (PAR); they are one and the same.
It's also important to note, again, that regarless of any of these numbers, the shape of the samples from an analog source ARE NOT DEFINED BY THE NUMBER OF LINES.
Oh, one more thing...most multimedia NLE and encoding applications provide precise control of all of these settings. Just an FYI. All the best my friends.
What's the best way to deter a thief? Ruin the spoils, of course. Verizon, AT&T, T-Mobile and Sprint have agreed to a broad outline that will culminate in the creation of a central database for stolen cellphones. The goal? To block lifted units from functioning on US shores. Over the next six months, each firm will build out its own stolen device database for integration into a larger, central database, said a Wall Street Journal source, with regional carriers joining the effort over the following two years.
I probably should’ve just dropped the mic after the last post, but we’re going to continue on. I’m not one for dropping names, and in this case I don’t have to either. Everyone has gotten this wrong at some point, and I mean everyone. The people working on related standards; the people making the world’s leading non-linear professional editing systems; the people who make a living professionally processing and transcoding video; the people making multimedia playback software; the people making DCCTV systems; the people making operating systems; and yes, even forensic video and digital evidence technicians and analysts. We’re all human, my friends. It is a long, convoluted, complex process with its very foundation based on sampling an analog signal.
We've already been hands-on with NVIDIA's first Kepler GPU, but all those fancy features count for nuthin' if the benchmarks don't back them up. So do they? Huh? Do they? NVIDIA told us to expect a 10 to 40 percent performance boost from the $499 GTX 680, versus AMD's pricier Radeon HD 7970, and it appears that was no exaggeration.
You can just press play if you want to, but if you're forensically processing evidence, I wouldn't advise it. Know the playback software, as it is just as important to proper playback and interpretation as the hardware. Take Windows Media Player, for instance.
In the following video I discuss a few quirks about Windows Media Player v12, a shortcoming of the popular metadata tool MediaInfo, and more.
Photographers using the newer high-end flash memory format now have another supplier besides Sony for the cards. Also: a big, fast SDXC card for a big, fat price.
Fellow LEVA instructor Detective Keith Swanson of the Scottsdale, Arizona Police Department, is compiling data for a DME white paper. If you haven't already, take a moment to complete his very brief survey.
This week the SWGDE released a couple of new DRAFT documents for public comment relating to DME acquisition. The links below are directly to the related PDF documents. For more information please visit www.swgde.org:

Developers Ronald Bultje, David Conrad, and Jason Garret-Glaser are creating a native VP8 video codec implementation for the open source FFmpeg project. The aim of this effort is to bring first-class VP8 support to FFmpeg and demonstrate the feasibility of producing an independent VP8 implementation.
