Get Open File via Applescript

Hello!

All my tasks off ffmpeg cen be done via Applescript (GUI scripting), so I can do convinient batch encoding. But one important thing I can't get to work:

How to get the file I have in the Open text field?? I need a script, that does a drag and drop of a file on the app, or a way to select a file via file browser.

The easiest way would be to be able to write text in the Open Text field, but sadly it's read only

Any ideas? Thanks for tips! Would be really, really great!

greetings,
Stefan

Have you tried using the Finder to send the open event to the app with your file as a parameter?

tell application "Finder"
open "some:file" using application "ffmpegX"
end tell
