Are all (or most) of the clips in the DBZ opening theme song from the series episodes? Link to the opening theme song:

I can recognize a few clips as being part of the series (e.g. Nappa tearing through the planes).

But the rest I cannot recollect being anywhere in the episodes. Do they appear in any part of any episode? If yes, is there a list connecting them?
Most of those clips are from the movies.
10s-21s;30s-36s : The Tree of Might
21s-30s;36s-38s;41s-45s : The World's Strongest
38s-41s : Dead Zone
