Video editing now a days is not a difficult task. In early days editing a video was a challenging process because that time the technology was not so advanced as now. Now even shooting a video is as easy as walking a one step. Every one have a smartphones in their pocket. They instantly shoot the video and upload videos online. But there is a huge difference in shooting video with mobile phones and a high quality, well shooted video. A video is said to be well produced and high quality only when it goes through video editing and sound mixing during post production.
Why to Use Post Production
A video without going through production process is just like a without make-up. Much of the work is needed behind the scenes after the cameras are done rolling. A lot of careful work is required. Because even a small poor work will reflects in the eye of the people because of regular habit of watching lots of video on regular basis. Spoiled or bad choices such as poor timing, awkward cuts are not able to convey proper message and the video will not satisfy the visual requirement. Remember that a good video is an investment to success.
Modern editing software's allows to arrange the clippings whatever order according to the requirement. We can try different footage's and different takes. Speaking directly over the camera versus recording of the voice creates much difference. So combining these two by putting them all together is the value of the post production process.
Basic Editing Tips
If you want to be a part of post production process then it must needs a proper post production training under the experts because the software's used are very big and complex, each tool and functionalities should be learned properly.

Do experiment with the software and see what happens. Improve the editing by regularly watching the outputs and take feed-backs.
