Understanding video standards is fundamental to aspect ratio correction. Back in the predominantly analog days we had three main standards referenced or used for most video recordings; NTSC, PAL, and SECAM. Then in the early ‘90’s came the first digital multimedia frameworks to reach the average consumer; QuickTime and, shortly thereafter, Video for Windows (VfW).

Today we have dozens of multimedia frameworks, digital video and digital display standards, all of which lead to a great deal of confusion regarding the plethora of acronyms and what they truly mean. AVC or H.264? HEVC or H.265? CIF or SIF? Don’t even get me started on the profiles and parameters available for each standard, as the combinations are truly mindboggling. When it comes to proper Display Aspect Ratio (DAR) though, it really boils down to “Are the originally recorded pixels square or non-square?”

I was out in Indianapolis last week to assist with the LEVA Level 1 training course. Another great week of forensic video and DME training provided by LEVA, and hosted by the University of Indianapolis.

It was an action packed week both in the classroom and out with students learning and practicing DME fundamentals, and the City bustling with NBA playoff and Indy 500 activities. Thank you to LEVA, their staff, my employer Ocean Systems, and the students for such an incredible opportunity.

Safe travels home everyone and have a great holiday weekend!
