I'm looking at developing an Applescript that will take a source

compression settings (FPS, quality, codec) for streaming.
Applescript can
tell Quicktime Pro to export movies using the export presets already
included in Quicktime Pro, but I am wondering if it is possible to add
custom export presets?

The answer to your question is yes, with some caveats. You can
preserve any arbitrary export preset using the following process:
1) Open a movie representative of the kind you'd like to export
2) Choose "Export" from the "File" menu
3) Select the desired export kind from the "Export:" popup menu (Movie
to QuickTime movie in this example)
4) Click the "Options..." button to specify your custom settings, then
click OK
5) Note that the "Use:" popup menu now displays "Most Recent Settings"
6) Start the export by clicking on the "Save" button (if you don't
start an export the "Most Recent Settings" won't stick)
7) Cancel the export if it is a long one
8) To double-check the export settings, select the "Export..." menu
item again. The "Export:" popup in the export dialog should indicate
the last export performed and the "Use:" popup should display "Most
Recent Settings". Click on the "Options..." button to confirm that the
settings are indeed what you desire (you can skip this step once you
gain confidence that this process actually works).
9) Without closing the open movie, run the following AppleScript
tell app "QuickTime Player"
tell first movie
save export settings for QuickTime movie to file "My
Volume:Export to Xyz Format"
end tell
end tell
10) Repeat steps 1 through 9 for each export variation. Be sure to
provide meaningful names for the export settings files.
To perform the actual movie export, use something like the following:
tell app "QuickTime Player"
tell first movie
-- export various movie versions
export to "My Volume:Movie Xyz" as QuickTime movie ,
using settings alias "My Volume:Export to Xyz Format.set"
export to "My Volume:Movie Xyy" as QuickTime movie ,
using settings alias "My Volume:Export to Xyy Format.set"
export to "My Volume:Movie Xzz" as QuickTime movie ,
using settings alias "My Volume:Export to Xzz Format.set"
-- etc.
end tell
end tell
Keep in mind that there is only one "Most Recent Settings" for each
export type so you may want to make note of your settings in case you
want to go back and tweak them.
Thankyou, and I hope my ramblings make sense. :)
I think they made sense (and my answer is predicated on that
assumption). That said, I think both your question and my answer will
appear as senseless ramblings to the non-scripters on the list. ;-)
It actually made a lot of sense. If I use the first script to export
those settings, is there any way to invoke the settings manually when
exporting. it would be great to have a folder with all your "favorite"
export settings and be able to quickly use them without the second
batch script.
