That is an excellent video indeed. Looking at the timeline, everything is explainable. In the end, track 10 is the only track that matters and the sound clip on the microphone track to produce the final video.
To create this video, lenart placed clips on tracks 1, 2, and 4 for editing and a single I Love Travel clip on track 10 for alignment. He then removed that single clip on track 10 and produced the video and then placed it on track 10 with the I Love Travel header clip in front and produced it again as the final video and uploaded it to Vimeo. He did it this way in order for you to be able see the timeline on Directorzone on what he did.
Others might have done this differently like using the music track instead of the microphone track, etc. The result would have been the same. Again, the timeline allows others to see any templates used. That is why he left tracks 1, 2, and 4 for you to see. Technically he needed all those tracks to produce the video on track 10 but not for the final video. I am glad that he left those tracks for all to see.
