See this is where I have problems with the university system and the courses they seem to offer... For example, I would never, ever attend a 3D animation course if it didnt offer a healthy portion of digital video work - You need it as a grounding for everything afterwards. Its all very well to learn how to create and animate a beautifully detailed 3D scene, but if you dont know squat about film conventions, effects that you can achieve with different lighting, camera angles, movements, lens angles and the rest, you're not going to come out with the ability to make things look "natural". If the course doesnt teach you, for example, about shot sizes, most viewers wont know why, but they will find it more difficult to watch you productions than if they were composed with traditional shot sizes in mind.
Add to this that you have to have a pretty good grasp of digital video to do any compositing work, not to mention video effects and grading, and I would suggest that you look for a course that combines the two disciplines wholly. You can never hope to learn everything there is to know about either, but it is important you look to get a good, solid grounding in both.
