In terms of visual pleasure, no other media can probably match the power of 3D animations. 3D has come up late, but is coming up at a very fast rate. Many young people are coming up with their creative minds in this field, creating a revolution.

Video editors are in great demand with the advent of streaming videos and movie clips in websites. As this field is becoming highly competitive, video editors can expect keen competition for job openings. One can enter into the field of video editing, after completing the digital video editing course or a media arts degree. Video editors work with the production personnel using advanced editing tools to analyze, evaluate, trim, arrange and join scenes according to guidelines set out by the producer or director of the project. One can find jobs in the government film and TV production studios, web design companies, advertising and multimedia companies. They can work with independent production companies and for motion picture studios. Many such government agencies recruit video editing professionals. Most of the video editors are freelancers and so they can build their own career in the desired way and this is also one of the good choices. Pay scale: initially one can earn 8,000-12,000 INR per month and with experience and qualifications, it may go to more than 25,000 rupees per month.

For graphics and animation design there are several courses such as 2D, 3D, 4D animation along with VFX that a student or anybody can pursue.

There is a comparison asked for in this question. Video Editing Vs Advertising Management and Public Relations.
1. Video Editing is a single dimensional area where one shall work FOR the Advertising Management industry as well as for the Public Relationship work as well.
2. Editing is more of a Desk Job whereas Advt and PR Management is a comprehensive profile. The former keeps you in the later takes you to.field and vast areas of Public Interaction.
3. Editing is a Technical Skills; whereas PR and Advt Management is made of competence and multiple skills.
4. based on the experience I had in the Media as well as in Higher Ed, I would go for the Comprehensive Domain I.e. Advertising Management & Public Relations BUT I WOULD SURELY LEARN the nuances of Video Editing to enhance my Creativity and capability to manage that part of a bigger domain. Video Editing is a money earning work but quite 'small in impact'.
