@simrin-- There is no requirement that you work on films or videos. My brother is a multimedia designer and he has worked on lots of different types of projects like posters, websites, logos and games.
People with the same education can go in many different directions. Your career is going to depend on your interests, so I'm sure that you can try and do many types of design.
Plus, many people who didn't specifically study multimedia still work as multimedia designers. As long as you have a degree in some type of graphic art and you can conceptualize ideas and design them for whomever you are working for, I'm sure you will do fine. It's up to you whether you want to work for a web agency, a design studio or communications company.
