I don't think you will find anything in the way of a tutorial for either of those timelines, possibly not for any. Timelines are not a common thing that someone would normally tutorialize, though I could be wrong. While the first seems to have a bit more interactive features, it appears to be just a movieclip that moves to different secctions based on a button selection, which also triggers an audio file to play for that segment. The second appears to simply be a movieclip that is scrolled using a scrollbar... I didn't detect anything in the way of audio that changed when scrolling it.
Thanks for you response
