alice-teacher Alice tips: problems exporting Alice animations to .mov files

[Beth Simon]

All,

For "free" you can create movies up to 5 min in length using TechSmith's
jing program.  However, the free version creates .swf files.  You can (also
for free) share these using screencast.com  However, there's a bandwidth
limit on the free accounts.

For, I think, $15 a year, you can get Jing Pro -- which let's you create
.mp4 files.
Camtasia is a one time cost of $179 for academic pricing.

But I find jing Pro super easy to use -- much more so than the full camtasia
studio.
