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

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

CamStudio

Free
(Open Source!)

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.

Jing

Free
(Pro is $14.95/year)

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).

Making the Recording

Here are some guidelines suggestions for making a successful screencast recording:

  • Do a quick test first.  Fifteen Fifteen seconds or so will give you a good indication of whether your audio recording level is fine.  You may need to tweak it.sufficient.  
  • Pause a few 5-10 seconds before you begin speaking.
  • Speak slowly in a natural voice.
  • Begin with a one-sentence introduction of yourself and your subject (e.g., "Hi, this is........and I'm going to show you.......").
  • Viewers will be focused on your mouse pointer.  Try , try not to make extraneous movements or move around too fast.
  • With each on-screen action, tell people what you are doing to make sure they are following you .   (e.g., "Next I'm going to..." , "Now we will look at...").
  • Small flubs or pauses are not necessarily reasons to restart the entire screencast! You don't need to deliver an award-winning performance, just one that effectively conveys what you are trying to teach.  If If you are using a screencast product that includes editing capabilities, you can usually cut out the portions you don't want to be in the final recording. 
  • No need for a concluding sentence if it's clear where your lesson ends, but a brief recap of what you have shown is fine.
  • When you are finished speaking, pause a couple of seconds before stopping the recording.
  • Be sure to save your recording right away!

Your screencast will require some post-production work before it is ready for "prime time".  It's not a lot of work, but it does require learning some more features of the screencast software.  MinimallyMinimally, we need go through the following steps:

  • Create Creating a title slide
  • Fade Fading from the title slide to the recorded lesson
  • Fade Fading from the end of the lesson to a closing slide (which can be a re-use of the title slide)

...

If you prefer not to do this part yourself, that's fine.  We DuraSpace will do it for you.  Simply Simply send the video to jjmarkow@duraspace.org along with the title, your name, and your organization for the credits.  If

If you do want to try the post-production work, and your screencast software allows you to do this, here are some guidelines.

...

Optional:  Organizational Slide. You may add an Organizational Slide right after the initial Title Slide if you wish to add organizational branding to your screencast.  Please Please use the following guidelines if adding an Organization Slide:

  • Begin with "Screencast Contributed by"
  • Logo no greater then 20% of screen dimensions
  • Corporate tagline and three or four services (optional)
  • URL optional

Remember, if you prefer, we are happy to do your post-production work for you!
