Timeline of credits in an opening sequence

I looked at The Purge's opening sequence and noted down the timings and the names of the credits and created a timeline. By doing this i could get an idea of how to time my credits correctly, for instance how long one credit should appear for and how many should be displayed at once. This has influenced my opening sequence as i am now able to figure out a clear and sensible order the credits should go in. Not only by looking at the timings and order of the credits have helped but also looking at the style of the credits for example the font, colour and size have also benefited me. As the genre of my opening sequence is thriller i need to choose appropriate credit styles to link to the genre. So by looking at a thriller such as The Purge i am able to now design credits that are suitable and effective.
