1. Open Compressor.

2. If you completed the previous exercise, find and highlight the JPEG Image Sequence 50% preset we created in the Settings tab within the settings window. If you did not complete the previous exercise, you may choose and highlight any one of the presets from the Settings tab.

Right-click on the setting and choose Save as Droplet...:

3. In the Save dialog box, you can name the droplet to whatever you like, although it usually makes sense to keep it the same as the setting name. Pick a location where to save the droplet. We'll save them in a folder called Compressor Droplets in our Movies folder:

4. Quit Compressor (by pressing Command + Q).

5. In Finder, navigate to where you saved your new droplet.

6. In a second Finder window (easily created by either double-clicking on Macintosh HD or by hitting Command + N), navigate to a folder that contains a video file you want to compress to the droplets' settings:

7. Drag-and-drop the video file on top of the droplet:

An application simply titled Droplet opens and a window appears. Here we can adjust a couple of last-minute options:

8. The default Destination is set to Source (meaning the location of the source media) but you can change this if you like.

Most interesting to note, however, is the + button which lets us add additional presets to our video. For example, if we wanted to, not only could we create our JPEG image sequence, we could hit the + button and tell the Droplet to upload a version to YouTube as well!

9. Click on Submit. When the additional menu pops up, click on Submit again (there's more info on this window in the previous recipe).

The compression process begins. The file appears almost immediately, but may take a while to fully finish compressing, depending on the preset. An image sequence generally does not take very long to create. Check out the There's more... section on how to observe the progress of the droplet.
