It depends on what you are ultimately planning to do with your video.
Do you plan to share it online? But it on YouTube or Vimeo? Add it to a web site?
Output it to DVD or BluRay disc?
Use the output video in another video project?
Share it as a podcast?
Output it for download to a portable device, like an iPod or iPad?
Each has its own unique tech needs. There is no one-size-fits-all solution.
