Converted to Flash flv, 480x360 at 15fps
Converted to Flash flv, 240x280 at 15fps
ffmpeg conversion of the NetLogo Model Camtasia screen capture
This is a movie of a screen capture sequence with cartoon ballon callouts added by Camtasia. This is a very different type of original material may require different settings to produce optimal results.
The text quality is poor. A useful strategy if the small sizes are useful is to enlarge the Camtasia callout balloons and the text it encloses.
Here's a high-quality QuickTime movie: NLphotosynth_intro.mov.
Here's a much smaller Camtasia movie mebedded in a swf file: NLphotosynth_intro2.swf
Converted to Flash flv, 472x372, 15fps with audio
Converted to Flash flv, 236x186, 15fps with audio
