This is part three of the testing, where I’ll focus on the encoding speed setting and its effect on filesize and audio quality, in reference to voiceover audio.
Published SWF Files
Filesize Comparison
Summary
To my ears, the encoding speed set to 0 sounds the best. And amazingly, it yields the lowest filesize. So far, it seems that a setting of 48-44-0 is the best for voiceover-based Captivate movies. I’ll do some further testing this time will large, real movies that contain slide data and a lot of audio (including some music), for the next post.

Hi Mark,
I surfed over here from the link on Silke Fleischer’s page. Thanks for the indepth research on the encoding bitrate. I have been using something very similar with 56kbps-44.1 but never went to the zero setting. I’ll try that next time to squeeze out some additional filespace.
By the way, after looking at your profile I realize that we may have been on cruise together probably in 1994 - 1995. I was in the Constellation’s airwing at VS-38 when the Lake Erie was out on that cruise.
Small world. Finally, someone else who knows what Abu Dhabi means, or at least where it is…
This is great! Thank you for taking the time and effort to block this out systematically.
Now, does anyone know what “encoding speed” is doing?
As a new user of Captivate trying to publish my first project, I found your posts covering exactly the information I was contemplating creating for myself. This is a great time saver and your logical low tech analysis is very much appreciated.
