Mass Communication

You think you are talkative and can entertain people with your talks? Well, you are qualified to be a VJ. You must be camera friendly and confident. Little personality, good delivery and presentation is the key. Keep it interesting and being yourself will make your things easier. Along with that, excellent body language and dress sense, a pleasant voice, good command over the required language depending on the medium, presence of mind and a good knowledge of music would be good for anyone who aspires to be a Video Jockey. Awareness of whats happening around you is also vital. Be socially active.
You should have a wonderful sense of humor to make the show interesting. You may also be required to work erratic hours and travel extensively. You should love music and should be aware of all kinds of music. With the changing trends, you also need to be well informed generally on topics like politics, travel and what all is new. He/She should be well aware of all topics like, politics, travel and what all is new.
Be as quirky as possible and don't forget to add your own touch.

The hierarchy or the organizational set up of an advertising agency keeps both these profiles and do have a different scope of work as well as a profile for them.
A copywriter is a person who writes. This writing is of scripts of jingles for audio or video advertisement. This may be the text of a printed advt. material. The copywriter is responsible for composing the concept and bringing the words that make the best impact and create a brand of the advertised product.
The art director is the person who does an altogether different but comprehensive work than a copywriter. It is the art director who designs an advertisement of print or audio or video.
The art director is primarily the leader of the set up of shooting set where a TV or video commercial is shot. This way, a copywriter is someone who composes things in sync with the Director and Art Director's Concept and plan.

The skills needed are somehow identical as both relate to the camera. The VJ job is informal and carries some casual aspect of presentation whereas, a news presenter is to be a formal, disciplined, strong and firm in communication, balanced in opinion as well as highly informed about topics of politics, social matters, education, economics and others. Basically, general awareness is needed. Formal mass media education, electronic media education or degree can increase possibilities of getting a job in news houses. Salary, I quote the same as I said for VJ- No Final Word. However, I have an idea that it stars from 15-20k per month and ranges towards 50k for beginners with some experience or fresher. The day you get experienced and known you get unending growth.

This question needs two submissions from the student's side:
1. what are the academic or educational credentials of the person?
2. Based on what skills, expertise, experience and appearance does the aspiring video jockey wants to claim the job?
Answer by assuming that the person is having some substantial education like graduation or something which makes him or her a literate person. I shall not recommend the observation that even an illiterate person can become an VJ. So proper education, excellent language skills in the targeted or demanded language, fluency in speaking, sense of humor and courtesy, improvisation in the live speech, no fear of stage or acting along with an impressive and pleasant personality. Proper training and exposure to the camera and presenting oneself to camera and audience in a live mode needed. Some good videos are already available and shared on Youtube and participating in regular RJ and VJ Hunts will also open possible jobs. Now comes the salary part:
No final word can be given on this. It may be thousands or even Lacs per month for someone who works with a reputed brand of a channel. Who starts as a fresher may get to the average package of the industry as given to other media profiles. I repeat, no final word on salary from my side.
