There may be a need for compressed powerpoint slides to use while speaking at a conference. I have summarised my review of using wikis in distance education, and compressed these using Impatica here - being careful to upload the WikisODE.imp and ImPlayer300.jar files into the same folder as the WikisODE.html file. This time round, I avoided using full screen jpg picture as background since this delays streaming, and used a standard Arial font - previously Arial-rounded and Lucida Calligraphy (my preferred fonts) did not go through Impatica. Naturally my voice will be live as standard in conferences. I am not sure if they would accept a voice-over-powerpoint to count as a conference presentation - not at those I have been to - although I have heard some conferences have video sections where the author and speaker are absent. Voice-over anyway has been done earlier. Here I set out to see the what minimum size could be achieved for a practical conference presentation and the result is 7 minutes speaking and 30.8KB file size.
