Maybe this is a bit off topic: are there any apps that can 'record' the actions done in an application: so *NOT* which tasks (I bet Applescript can do that) but what happens on the screen ... Think of it as a trainee-movie...'First you do this, then you go there...etc.'

Of course this would be possible with an Mac-to-TV out on video, but I want to capture it directly within the finder. Kinda NONSTOP screencapture....
Could that be done with Applescript as well: 'Tell Finder to take ScreenShots 15 x per second' ?-)

Any help would be much appreciated...

Hi Arno,

You could try searching for a public screen-capture script at the standard AppleScript web sites, such as the AppleScript Sourcebook, AppleScript This Week, AppleScripter.com (OLD), bbs.applescript.net, Just AppleScript Weblog, or the ScriptWeb home page.

If there aren't any suitable public scripts, then it should be fairly easy to write your own. Any keystroke-simulating scripting addition (OSAX) can capture the screen in PICT format, via the standard keystroke & modifier combinations ['Command + Shift + 3' (screen -> disk), or 'Command + Shift + Control + 3' (screen -> clipboard)]. For instance, either the Sändi's Additions OSAX (e.g.: TypeText "3" with Command and Shift), or the comprehensive Akua Sweets OSAX (e.g.: input state {keys down:"3", command key bit:true, shift key bit:true}, or input state {keys down: "3", transient keys: "CS"}, or input state {keys down:"3", modifier keys:"CS"}) will let you trigger a screen snapshot. Normally, these commands do not even have to be enclosed in a specific 'tell application "..."' block, since they are triggering a standard global hotkey. [However, note that some of these OSAXen may have a few problems under Mac OS 9.0.x, where certain modifier combinations (particularly involving the Control key) may not be recognized in some apps or in the Finder. If you do encounter any issues, try using Eric Grant's Sigma's Additions OSAX instead.]

In any case, when you have a working script that captures the screen once, you could either enhance the script by adding an "idle handler" routine to periodically execute the appropriate command, or just use a separate scheduler utility to periodically run the script. (E.g., a free "lite" version of the iDo Script Scheduler utility is available on the Mac OS 8.6 and Mac OS 9.0 CD-ROMs, or can be downloaded from Sophisticated Circuits' software web page).

Regards,

--Paul

For an easier (but non AppleScript) solution, you could use ScreenMovie from http://hotfiles.zdnet.com/cgi-bin/te...3348&b=mac

Thanks you guys: someone mailed me this site: http://www.pure-mac.com/screen.html

which indeed offers multiple solutions (including ScreenCapture)
Haven't checked the AppleScript opions yet, but the apps. I found here are pretty powerful.

Thanks !
