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.
Forensic Focus, one of the digital forensics community leading sites, dedicated an article to the most interesting presentations at the conference, and we are proud to be highlighted:
“Authentification of data was another focal point of the conference; Martino Jerian from Amped talked about the difficulties of validating images for use in criminal cases. Identifying whether an image is an original file can be challenging, but the main issue is with the authenticity of the image’s contents. Three of the main things that Amped look out for in image validation are recapture, staging and misrepresented content; once they are sure that none of these are problematic, they analyse the image itself for signs of modification. Even a relatively simple technique such as cropping or editing the colour saturation can have a strong effect on the perceived meaning of a picture.”
