There are tutorials, but they are badly outdated as the new cinematics editor is completely different. Try YouTube. There are a few there. There is one that blizzard made as well. While it doesn't cover specifically what you want, it's still a nice tutorial. Additionally, look in the tutorial forum section if you haven't yet and search for cinematics or something similar. You might find something there.
I am also not too familiar with the camera actions in the trigger editor, so try playing around with those too, you might find something useful.

Link to Blizzard's cinematic tutorials.
If you want a tutorial of the editor itself, go Here. While very basic, Blizzard still does a nice job teaching the basics.
