Videator provides some export presets. You can modify these presets and create your own export settings.

To create a new export setting:

1. Choose File->Export Movie to bring up the Export Settings window.
2. Click the + button.
3. Use the Quicktime Movie Settings dialog to specify your export settings. When you’re done, there should be a new export setting, named something like “Setting #1”.
4. Double-click on the new setting to edit its name.
5. When you’re done, click OK. A Save File dialog will appear; you can cancel if you don’t want to export your video at this time.
