WhatCamtasia Relay is an application you can run on your PC to record a screen cast or presentation. This software is often referred to as "lecture capture" software, and is freely available to all U of M staff. Here is a link to the U of MN download page for the Relay software.
WhyLecture capture software has lots of uses, not just lecture capturing! I use it often to turn in assignments and updates for class here at the U, and also to record tutorials for Quick Bytes. It is the perfect tool for a no-frills "classroom flip." And I know people who use it to simply rehearse their presentations and watch them back. (Wait--people rehearse presentations? What a concept!) The application also provides a one-click publish to YouTube. And it's almost literally a big red easy button.
Camtasia Relay is similar to Adobe Presenter, a tool widely used in Extension in the past. If you are interested in a free (Presenter is $75/year) and very simple similar tool, Relay might be it! Presenter has some added features, like the ability to re-record a single slide and add quizzing, that Relay doesn't have. But Relay videos can be watched on mobile devices. So there's not a clear winner for lecture capture.
How ToA tutorial on setting up Camtasia Relay: (which I had to record in Hangouts on Air, because you can't record yourself recording yourself with Camtasia Relay! Gah head exploding!)
But wait! There's more!
Here is a bonus tip on how to have Camtasia Relay one-click publish to a program team YouTube channel (as opposed to your individual YouTube channel).
Note: if you do not have a program team YouTube account but think it sounds like something you might want, contact Alison Link, Extension academic technologist, BEFORE setting it up for quick and easy instructions. She will help you set up an account that allows multiple users, and help you get the channel set up right from the start.
