Are the differences between Advaita Vedanta and Buddhism merely semantic/perspective? having studied Buddhism and Advaita Vedanta, I've seen that the differences between the two are almost non-existent.

This video does a good job at fleshing out the Vedanta and Buddhist perspective and he himself seemingly states that the differences between the two are trivial at best. 

I'd be interested to hear some input from those more familiar with Buddhism.
Buddhism teaches Anatta (not self) and the Nibbana is the final goal. You can't find them in Advaita Vedanta. Buddism also has Noble Eightfold Path with a clear set of instructions as to how to attain Nibbana. In my opinion, it is just more than semantics. The only way to be sure is to study and practice both.
