Squeeze 6 and higher has the ability to export directly through iMovie.
- Once your project is complete, go to Share>quick time export.
- Change the Export to Movie to Squeeze.
- Click the Option button to the right.
- Change your output format to the one you would like.
- Once your desired output format is selected, you will see the listed presets associated with the output format below.
If you would like to publish to Sorenson 360 or any of the other available publishing options, this will happen automatically given the selected preset has a valid publishing option already attached. if you are not sure if the presets listed have your desired publishing option, you can make a custom preset with a unique name that is easy to identify from the iMovie interface.
