Synopsis: More and more frequently forensic video specialists have to analyze video and audio that comes to them in the form of a digital video file. Sometimes these files can be easily imported into a forensic system; sometimes they refuse to import; sometimes they import on one machine and not another; and sometimes they import but look corrupted, slow the system down or cause the system to crash. Related issues arise for the specialist who wants to be able to export and share these or other video files. These files not only need to be of high quality but they also need to be compatible with the recipient's computer.
By considering how digital files look to and are dealt with by the computer, this session will offer the user insights that will help eliminate the guess work of deciding what to do in these situations. We will explore the digital representation of video and audio, video and audio codecs, media file formats and the facilities both within forensic applications and within the computer systems themselves that play a role in dealing with media data.
If you are going to NATIA's national conference this year, make sure that you stop in and see Jeff's presentation. Jeff's a good guy to know when it comes to questions about dodgy digital multimedia evidence.
