A Video is a series of moving pictures, typically accompanied by sound.

Formats & Codecs

  • VLC - Codec: (full list of all the main codecs used on the web, and several others not used much on the web but more for media distribution i.e. CDs/DVDs/Blueray/GameDiscs/Theatre/3D/VR-360/etc, since VLC plays just about everything)


  • MP4 (MPEG, Layer-4; the defacto standard came out in 2001 but only rose to prominence 2007-present after Apple chose it as their initially preferred mobile video format for iPhone & iPad devices; it is based on Apple's MOV with added MPEG metadata, and its use still has potentially complicated commercial considerations)[1]


  • OGV (Xiph's Ogg-Theora Video; the most popular of the completely OSS option from its introduction in 2008-present, as an alternative to ".mp4" in instances where you'd be worry about being able to pay required MPEG license fees and/or lawsuits/fines/penalties for non-compliance; as an act of defiance, it was initially the only HTML5 video format Mozilla's FireFox supported and still only supports ".mp4" via Operating System dependencies to avoid themselves of their users being subject to additional royalties)[2][3][4]


  • WebM (Google's Web Media format introduced in 2010 as a high-compression/high-quality option that has fewer license restrictions than ".mp4", that saw stronger uptake in 2015 onwards via Android apps & media players making it their preferred video format)


  • FLV (Adobe's Flash Video format, the original behemoth of online video and streaming from 2000-2012, and has since seen usage dwindle, fading into obscurity by 2020 due to Flash's EOL)


  • 3GP (Third Generation Partnership project ".3gp" Mobile video format, used to record, download & playback and/or stream to early Mobile devices 2000-2007 with minimal graphics and display capabilities)


  • MPEG (Moving Picture Experts Group's original .mpeg/.mpg video format, originally more popular for home video & "digital handicam" shot videos than professional online video, a market which went to its ".mp4" successor)


  • DIVX (late 1990s DVD format, as well as eventual early "hybrid HD" streaming format)


  • AVI (Microsoft's Audio Video Interleave format introduced in 1991)


  • WMV (Microsoft's Windows Media player Video format)[5]


  • MOV (Apple's Quicktime Movie format, an updated 1998 version of prior 1991 "Quick Time File Format" or QTFF with support for more features such as Panoramic video, chapter markers, multiple video/audio/subtitle inputs, etc)[6]


  • RM (RealMedia player's ".rm"/".rv" and related video formats was a pioneer in online video from its introduction in 1997 into the early 2000's, but was eventually surpassed by superior options in the "video streaming wars")

Video Truthing

Video Truthing is defined as specifying an object's location, size, orientation, and other metadata across each frame (of which there could be thousands, millions or even billions, depending on the length of the video).

Usages of Video Truthing include: identifying missing persons, tracking down most-wanted persons, picking out license plates of stolen cars, analyzing hours of surveillance camera footage for a particular person or event (i.e. find the point a crime occurred), checking for cancer during a live scope, MRI, etc, and many more pracitcal uses in government, health care, military/police, security and more.
