I have to disagree.
Placing animations in Movie Clips has little effect on performance with
the 2 following conditions.
1) Size of the file will increase about 30-40 bytes.
2) If the Movie Clip is big it might affect the streaming because all
of the Movie Clip needs to be loaded into memory before it will be able
to start playing. In fact everything in the same layer of the same frame
needs to be loaded before anything in that frame will play.
Many designs will have no problem at all with the above conditions,
others will bog down.

Nesting Movie Clips in of itself is not a major problem except as noted
above.
Again remember everything in the nested Movie Clips as well as the
original Movie Clip needs to be loaded before any of it can play.
If you have multiple actions occuring on the stage at the same time,
things are going to bog down based on how complex and how much of the
screen is involved. Whether the objects are in nested Movie Clips or
layered on the main timeline makes little difference.
I and others have many examples of things on the Web with 3 levels of
Nesting. Check out the Score where I use 4 deep nested Movie Clips.
That is graphics nested inside a Movie Clip which is nested inside a
Movie Clip, inside another Movie Clip, which is inside a Movie Clip on
the Main stage.
The same animation plays the same when it is a simple 2 deep nested
Movie clip even on slower computers.
