Sound & Video Editing

You may think of the following courses depending on the qualifications you already have:
1. If the current course is done after doing graduation then a Post-Graduation in Mass Communication/Mass Media/Media Production can also be good for you. I shall not hesitate to suggest even a Master Degree in A Language- English, Hindi or the one you see as an additional strength for editing and proofreading works.
2. If one does Certificate in Proofreading and Editing after class 12th, pursue Graduation as a must to do thing. Any Stream you may choose keeping in mind that an Alternative Career has to be met openly. Proofreading and Editing Job can also be a part-time thing so you have enough time to do another degree or Higher Studies.
3. If this Certificate Course is done by someone who is a Master Degree Holder, if not in Language or Social Science, Humanities, do one degree.

Audio-video editing is technical learning and will need some language and other mass media skills to bring growth in career.
The certificate you are pursuing in editing and proof reading is a good way to join the media jobs, as content writing and content editing-proof reading is quite a good career. From media/journalism writings to website developments, this task has a role.

The answer is a big no.
Audio-video editing requires a candidate to not only learn the intricacies of the software, but also learn minor things like how to dump an audio/video file from the camera/any other recording equipment to the computer. This isn't something one can mug up from text books or internet because it requires the concerned person to learn the skills over time and enhance them for the better under able guidance of the teachers who can help in sorting of the pros and cons one needs to take care of during editing.
Also, an audio/video editor should also have a better insight into how can one record/shoot a certain audio/video in a way that least editing is required on the system. Without practical experience at the editing desk, this will be a task which will be very difficult to complete.
And this holds true for India as well as abroad.
