How to Create a Screencast for the DuraSpace Educational Curriculum
Introduction
A screencast is a video of someone showing how to do something on a computer. The screencast software captures what is happening on the computer screen along with an audio recording of the speaker explaining what he or she is doing. Many people enjoy learning online procedures from screencasts, and the DuraSpace Educational Curriculum makes frequent use of the screencast format for teaching people how to use or deploy our software.
You can create your own screencast and contribute the resulting video to the online Educational Curriculum. There are four parts to creating screencasts: 1. Planning what you are going to present, 2. Choosing screencast recording software, 3. Making the recording, and 4. Producing the final screencast video. This guide will walk you through those steps.
Planning
First, select one of the curriculum topics for your screencast from the table of contents for one of the products. Good topics for screencasts are ones that show people steps for completing a task online. The viewer will be viewing a recording of your computer screen, following your mouse movements, and listening to your explanation of what you are doing.
Video Tools
The following tools may all be used to perform Screen and Audio capture for Screencasts:
Tool Name / Link | Cost | Platforms | Containers C ontainers and Codecs | Notes |
|---|---|---|---|---|
xvidcap | Free | Linux | mpeg(4), avi, mov, others, with sorenson, divx, mpeg, others. | Default versions do not work with pulseaudio, and thus recent Ubuntu installations (Ubuntu 11.4 and 11.10). Workaround is to install from source, and launch with padsp. Provides a GUI, easy to use |
ffmpeg | Free | Linux | Anything except apple pro | Pure command line tool. For Ubuntu, must build from source (directions), and then command lines like these. FFmpeg is also suitable for format conversion and audio overlay. |
recordmydesktop | Free | Linux | ogv (must transcode results, can use transmageddon) | Works out of the box on Ubuntu 11.10 |
Free | Windows, Mac, Linux | MP4, AVI, FLV (also save directly to YouTubeHD or Screencast-o-matic.com acct) | Runs from browser (Java applet), but records any screen/desktop activities. Has an easy setting for recording in "Full HD" resolution (1280x720). Can auto-letterbox smaller resolution recordings when saving. Very easy to use. Can highlight mouse cursor & all mouse clicks. 15-minute recording limit (Pro is unlimited). Videos are branded with a small logo in lower left corner (Pro version is free of branding). | |
Free | Windows or Mac | FLV (Pro version also offers MP4) | Easy to use, but has minimal options. Seem to only be able to record either full-screen or a specific window (no options to record a selected area or part of screen). 5-minute recording limit. Videos are branded (Pro version is free of branding). | |
Free | Windows | AVI or FLV | Lots of options/configurations available (most often compared to Camtasia in terms of options). Not always as easy to use or user friendly as other free screencasting tools (see Screencast-O-Matic or Jing), but it definitely comes with options & tools comparable to Camtasia. | |
$299 | Windows or Mac | MP4, M4V, AVI, FLV, Silverlight, MOV, RM | The most fully featured screencasting software out there, and very easy to use. But, it comes at a higher price. |
