I have been working as a video editor and animator for the past 10 years. For over 10 years now, I developed a keen understanding of the life cyle of video editing. I have edited several corporate films, documentaries, weddings and a few television shows in the course of my career. And some project that require an advance green screen keying. The link that you shown are combination of 3d that are done in different platform like Maya. I have 5years using AE and I can customize an AE template only if all the element are done in AE.
