Here was my post on MacInTouch about "Flash screen recording" software:

Have been trying to find Mac software that does "screen recording to
Flash (SWF)". Did searches on Google and VersionTracker and came up
empty. In the PC world there are several such programs that are
excellent for software demos and training.

For screen recording, the Flash format is much better than video
formats such as QuickTime or AVI because the files are much smaller,
playback starts almost instantly without any stalls or jerkiness, and
you can make it interactive. Notes, captions, callouts, commentary,
and sound effects can be easily added.

Here are some examples of the Flash-based software demos:

1. [Backup Movie]
2. [File Scavenger]

Here are some PC-based "screen recorder to Flash" applications and
all offer free trials:

1. ViewletCam ($99)
2. Macromedia RoboDemo (formerly Flash Cam, $499)
3. BB FlashBack ($199)
4. Camtasia Studio ($299)
5. FlashCast ($129.99)
