Post production is where your footage comes together to become what you had envisioned. Here, you can edit your footage, arrange it to convey exactly what you want. This can be the most difficult step in the process because you need to have working knowledge of the programs that help you organize and solidify your production so far.
In the Media Center, we mainly use iMovie for the regular user and Final Cut Pro X and Adobe Premiere for the more advanced users.
The polished product you produce is something you can be proud of.
The library has a subscription to O'Reilly Technical Books. Many of these books cover many mulitmedia programs that are used in the Media Center.
We use Quicktime Player for screen capture. It is found on all of the Apple computers in the Media Center. It can record a computer screen a selected window, a webcam or even just audio. It is very useful.
Skype now has the ability to record video if you have to capture video via webcam.
