The ArcGIS Full Motion Video Add-In has been updated to include two sample video clips with MISB 0104.5 metadata and two brief tutorial exercises. The 10.0 and 10.1 versions have each been updated.
The exercises walk you through the process of adding a video file, playing a video, and seeing the image footprint on the map. They also show how to zoom to the extent of a video,and how to collect geographic features by clicking on objects visible in the video.
New demonstration licenses that time out November 30, 2012 are also included.

This is a great addition. Is there any plan to adding support for full motion video in ArcGIS Online pop-ups?
We have no plans to support ArcGIS Online pop-ups with FMV at this time. We are, however, working on adding FMV to other applications. Keep an eye out on the blogs for upcoming announcements.
Provided license file is licenses the addin only for ArcGIS Desktop Single Use. As during licensing the message shown is”Full Motion Video for ArcGIS Desktop Single Use”. As I have concurrent use license, I am unable to use the add-in. Please provide the trial license for concurrent users as well.
Secondly, would this add in support video with Ley Length Value (KLV) standards as well?
We will be supporting concurrent licenses, but not for the temporary downloads. You may request a concurrent license once 10.1 SP1 ships in November. Yes, the FMV tool support KLV.
