If you only need to compress video to MPEG-4 for the iPod, then Techspansion’s iSquint will work great. If you want to take your non-interactive Keynote presentation and easily convert it to many different formats, you should give VisualHub a try. This batch encoding tool brings the complex task of compressing video to any user.

You can create iPod, PSP, DV, AVI, MP4, WMV, MPEG-1, and Flash video with the click of a button from many common (and uncommon) formats. You can even burn hours and hours of video onto a DVD suitable for standalone DVD players. You can get around some problems when using non-standard video (AVI’s) in Keynote by reading in the file and exporting a QuickTime compatible MP4 file.

Download and try out a demo of the software (limited to encoding approximately 2 minutes) from their “Try It” page. VisualHub is available for purchase for $23.32. Find out more at Techspansion.com
