The second last tab in the Project view is also the last step prior to the project publication. The Settings tab contains two different areas, whose changes must be saved independently.
Besides editing the basic data you already introduced when you created the project ─size, framerate and devices─ you can also change the quality of the published version ─by default, the adaptive quality is disabled─ and activate/deactivate the video preload. You should bear in mind that if you deactivate the video preload the project will launch more quickly, but it may not play smoothly if the user's connection is slow.
You can select what of your project's events are more important to you, the ones you would like to track and see the results in the metrics panel. The video and interactive elements you don't select will not appear in the panel. By selecting only the relevant events you will get a more clean and optimized metrics panel.
You can also select the analytics service you want to use to manage your data. The default service is Piwik ─the integrated panel─ but you can also select Google Analytics and ComScore.
