FFmpeg is a great tool to have in your toolbox if you’re a multimedia geek. If you live mostly in the world of Microsoft Windows and have dozens, hundreds, or thousands of files to process though they lose a little luster. Sure, there are tons of free applications built on FFmpeg that provide some limited batch processing capability, but usually they're just that; limited.

Some more offline comments and testing recently have raised a critical issue; the use of Square Pixel Sampling and Non-Square Sample Formats. Before that though, let's talk about validation testing.

In fact, I think we would all agree that when this level of detail really matters, you must validate. Lots of great resources out there about that topic.

As demonstrated in a series of articles published earlier in this blog, solid-state disks (SSD) tend to wipe deleted information on their own pace due to the way their garbage collection mechanism is designed.

The Media-Geek community is now well over 600 members strong and growing!  Although I was literally operating in a state of emergency for the entire month of April and on the road most of May, this morning I managed to finish a significant system upgrade for our site.  This upgrade provides better integration of the video posting capability, improves efficiency for many features and addresses a few other minor bugs.

A brief video discussing the basics of multimedia metadata analysis & some of the Open Source and/or Freeware solutions that can help. Solutions discussed include:

• Exiftools, by Phil Harvey - https://exiftool.org/
• MediaInfo & MediaInfoOnline - https://mediaarea.net/en/MediaInfo​

I was out in Tacoma, WA last week to teach our DVR Assessment & Video Recovery course, and to provide a free seminar on Digital & Multimedia Evidence for area prosecutors, law enforcement and support staff. It was a really great class, and as always the group discussions during both the class and the seminar were really interesting and informative. Thank you to everyone who attended for their participation, and many thanks to Kim, Chris, and the entire Tacoma Police Department for being such amazing hosts.

If you missed the free seminar, we’ll be back out that way to provide it again on July 8th at the Washington State Criminal Justice Training Center, in cooperation with the Washington State Homicide Investigators Association (WHIA).

If you’re interested in our DVR Assessment & Video Recovery training course, check out our upcoming training dates and locations or contact us to inquire about hosting one of our training events.

Thanks again everyone. Be safe out there my friends!
