• Convert Impress Presentation to AVI

    Here are some rudimentary steps to create avi's from an Impress presentation using recordmydesktop for use on a 1024x768 projector.This article assumes you have recordmydesktop, mplayer/mencoder, and ffmpeg installed. If not use your distributions package manager to install. I needed to be able to do this to use the created avi 'background' in Lyricue - a fantastic presentation application used by our church.


    • Create your graphics in GIMP.
    • Create your Impress presentation using those graphics – use a mixture of On Click animations (to start, for example) and timed animations.
    • Make sure your desktop display resolution is set to 1024x768 (or the same as your projector). (n.b. 1280x1024 is NOT the same aspect ratio as 1024x768!)
    • Start your Impress Slideshow with initial background – once recordbydesktop is running, you can continue with the first animation with your first OnClick graphic animation.
    • Run the recordmydesktop command:
    • recordmydesktop --no-cursor --no-sound -odesktop.ogv
    • Swap to the ready-to-go Impress presentation and step thru it as necessary. Once the presentation is finished, press CTRL-ALT-S to stop recordmydesktop recording (n.b. I had to alter my Gnome keyboard shortcuts because initially recordmydesktop couldn't assign that keyboard combination due to Gnome keyboard assignments(shade-up). Alternatively you can get recordmydesktop to use a different keyboard combination for 'stop recording' - check the recordmydesktop man page for more detail. Note there is also a Pause keyboard combination with recordmydesktop.
    • Run the mencoder command to convert OGV to AVI (xvid)

    mencoderdesktop.ogv -ovc xvid -xvidencopts pass=1 -odesktop.avi

    • Run the ffmeg command to chop out the cruft at the beginning (and end if necessary):
    ffmpeg -ssstarttimeinseconds -vcodec mpeg4 -sameq -idesktop.avidesktopdone.avi
    • Enjoy! (i.e. test on projector)
