I tested out powerpoint narrative recording with the SQL injection
I will spare you the results :-) but the main goal was to experiment and
find out how much disk space this takes and what the quality is.
Result for 5 to 6 minutes of recorded narration at 'radio quality' 43
kb/sec: 11 MB! That is quit big.
I would estimate that an average module of 45 minutes will result in 90
MB this way.
The quality seems ok, but some audio was skipped when I went to the next
Maybe this is because I used linked narration, which creates a separate
wav file per slide.
I hope there are better ways to do this, resulting in smaller 'webinars'
that can be downloaded.
Something I learned also: If done like this it is important to have a
written out 'script' of text supporting the slide.
This can be integrated as (part of) the slide notes.
