In a nutshell screen capture is the art of developing educational materials by capturing a video of what is happening on a computer screen. This simple process can allow rapid creation of rich-media instructional aides. In this talk I will present some experiences of mine and of my colleagues in developing these resources for students of Oscail in Dublin City University who are studying a Bsc. in Information Technology by distance education. I will look at some tips I wrote two years ago on this topic and examine their continued relevance. The take-home message of this talk will be “publish or perish”, an exhortation to the educator to focus not on fancy production or editing of screen captures but rather on a process that involves a minimum of time and technical effort to create videos and get them to students. To finish I will give an overview of how we are using Camtasia Studio with Google Video as part of DCU’s roll out of Google Apps for Education and demonstrate some interesting aspects of this elearning platform.

Editor's Notes
- Students of Oscail’s BSc. In Information Technology by Distance Education, edit a wikipedia article as part of their coursework. I used screencasts to explain how the Wikimedia software works and give students an introduction to editing Wikipedia articles. For information on editing Wikipedia articles with classes see http://en.wikipedia.org/wiki/Wikipedia:School_and_university_projects . I recommend it. Its lots of fun for students and gives a good insight (to teachers and students alike) into how knowledge is agreed and shared in the digital age.
- Tutor in Oscail’s Bsc. In IT demonstrating how to solve a CMP / PERT planning problem in the module Management Sciences 2. Camasia and MS OneNote with a headset on a tablet laptop were used
- Top tip for PowerPoint: When using Camtasia with other programmes the default is f10 to exit the recording (f9 for pause) However you may not be able to access this key on a tablet PC when you have the screen rotated on top of the keyboard. You can change this shortcut with the Screen Recorder under Tools >> Options >> Hotkeys. Change this to he Esc key which is usually visible
- File format has changed (now mp4 recommended) Bandwidth has increased (somewhat) Mobile screens have gotten bigger
- Don’t be seduced by post-production. Be disciplined and try and do everything in one take. Trust me this will take less time (both in the long and shot term) than getting sucked into editing. If it doesn’t work in one take, throw it away and start again. This is the only way to learn how to do it better. If you say “I’ll edit this bit out later” you will A. possibly never get around to it and B. never learn to improve your live presentation. Here is a diagram I use in presentations to show the production/editing stage in the workflow:
- Don’t strive for perfection (publish or perish): Get it out there. Get used to the sound of your own voice. Hear your umhs, aws and flaws but don’t get hung up on them. Record at a low resolution. Turn your screen resolution down to something like 800 x 600 before you record. Avoid pan and zoom. Instead try and stick to a fixed screen area. Zooms and Pans are distracting to the viewer (particularly for program walk-throughs aimed at novices) and more time-consuming to produce. If you are recording the whole screen or even a large portion of it you probably need to get back to basics. Don’t aim for ipod/mobile phone . If you are using Camtasia to record a PC application the resultant video will never look right on a mobile device period. The only thing that will look vaguely good on a mobile device is a carefully designed powerpoint slide with large font (and this is missing the point of using a screen-casting program like camtasia) . Put all i-somethings out of your mind unless you have a very very very good reason * * very very very - the triveriate closely related to the trirealiate: “trust me, it’s really really really safe”
- Batch publish. If you have a few videos, batch produce them to give them all a consistent look and feel. This is a very simple way to brand all your content and give it a professional feel without spending lots of time at it. I love this feature. It works great with a nice customised pre-loader with your logo if you know your way around Flash (or know your way around someone who knowns their way around Flash). The ten minute rule: Video is a passive and hypnotic medium if you’re video is longer than ten minutes add some interactivity, even if its just a hotspot to say “click here to prove you are still alive”. Consider cutting your video down to ten minutes altogether making it more modular and resuable Publish to Flash. Don’t get me started on how bogey windows media player files are. Flash (swf or flv) is a very mature cross-platform format optimized for web delivery. Don’t bother with the freebies. Its almost bad manners now days to expect people to pay for something but Camtasia has so much value for such a low price that you would be mad go banging your head against a wall with wink etc. I’ve already done the whole head and wall thing. Come back in a year when these applications have matured.
- Google Apps for Education. Google Video can render your screencast into the appropriate format (in this case MP4)
