When working on DVR videos, how many times do you have not just a single file, but a folder full of files from different cameras of different times?
An often overlooked tool in Amped FIVE is the Convert DVR interface that enables a user to pre- process files prior to loading.
It is good practice, when conducting any sort of batch processing, to work on a copy of the folder containing the evidential files. Although FIVE has safeguards in place to ensure you don’t overwrite anything, it’s a good habit to get into!
Here we have a folder containing our 4 evidential files.
Our friend David Spreadborough, better known as Spreadys, has written a bunch of articles on different DVRs he tried at IFSEC 2014. The articles are packed with a lot of very useful technical insights, which system producers should take as a checklist to improve their products.
The good thing for us is that (as Spreadys notes) most of the proprietary video files produced by these systems are easily reproducible with Amped FIVE. Continue reading
Today, David Spreadborough (better known in the community as “Spreadys”) posted an article where he has shown different ways of converting proprietary video formats in one specific case, with all the quirks of the method explained in the previous post about the topic. Amped FIVE is one of the tools used for the comparison. Continue reading
In a recent post, Larry Compton of DME Resources makes some excellent points about video format conversion.
Jim Hoerricks adds some further insights that are also related to Amped FIVE workflow, especially concerning our proprietary video conversion feature we are constantly improving.
The bottom line of the two articles is that, even if you have third party tools to decode the proprietary video formats, they are called “proprietary” for a reason. Thus you cannot be 100% sure of the results unless you test, verify, and analyze in depth.
I wanted to add something to the discussion. The following extracts are from Larry’s post, following some comments from my experience:
Dave Glover from our partner, GP Sift, will be at the MediaSolv booth #2407 showing the new workflow for converting and viewing proprietary video files in the latest version of Amped FIVE. If you’re in Washington D.C., come by and see it! GP Sift, MediaSolv, and Amped Software have developed an integrated workflow for homeland security specialists, investigators, intelligence analysts, and digital media forensic experts to provide the most effective solution in the industry.
If you happen to follow some forensic video analyst mailing lists, forums, and LinkedIn groups, you know that usually 9 out of 10 threads are variations on the theme “Who has the player (or codecs) for the XYZ format?”.
There are thousands of different proprietary video formats on the market, but most of them are not fully proprietary and employ standard codecs in a proprietary container.
About a year and half ago we introduced the possibility to convert some proprietary formats in Amped FIVE. When we tested that technology then, it working on around 20-25% of the formats we came across. Not a great percentage, but something is usually better than nothing.
With today’s release of Amped FIVE , we are expanding the compatibility to more than 70% of the formats we have in our database. As we cannot certainly have a sample of all the formats on the market, we expect that the user success percentage will be a bit lower, but should not be that much. Now instead of “something is better than nothing”, you have a fighting chance with conversion.
