Hot Folder

Availability: 1.0.5+

Permute 1.0.5 allows you to select a fixed destination and has AppleScript support, which in combination make it very easy to create a 'hot folder'.

What's a hot folder?

Hot folder is a folder, which is watched and whenever a file is added there, it is processed.

How to create it?

The magic behind it is in OS X and is called 'Folder Actions'. The following tutorial is for 10.6, it works on 10.5 as well, however, some of the menu titles are different, or in some submenu.

1) Create a folder for the input files and a folder for the output files.
2) In Permute, go to Preferences... (in the Permute menu) and in the pop up menu "Always save converted items to" select 'Choose folder...' and select the created folder for output files created in step 1). Do not select the ouput folder the same folder as is for the input, as it can result in an never-ending conversion loop (converted items getting added again)!
3) Open AppleScript Editor (in /Applications/Utilities/) and create a new script with the following text (experienced users can edit it for additional functionality):

on adding folder items to thisFolder after receiving addedItems

repeat with anItem in addedItems

tell application "Permute" to open anItem

end repeat

tell application "Permute" to start queue

end adding folder items to

And save this script to ~/Library/Scripts/Folder Action Scripts/ - where ~ is your home directory. You may need to create the Folder Action Scripts directory.

Note that the start queue command only starts the queue - doesn't wait for the file to be done converting.
4) In Finder, right-click (or Ctrl-click) on the folder and choose Folder Actions Setup..., which will bring up a list of scripts and you choose the one, you've just saved.
5) That's it! Drag'n'drop a video file to the folder to see if it's working.
