5.7 video editing

Video editing is the process of manipulating and rearranging video shots to create a new work.
Editing is usually considered to be one part of the post production process. Other post-production
tasks include titling, colour correction, sound mixing, etc.
Many people use the term editing to describe all their post-production work, especially in non-
professional situations. Whether or not you choose to be picky about terminology is up to you.
We use the word editing to mean any of the following:
1. Rearranging, adding and/or removing sections of video clips and/or audio clips.

2. Applying colour correction, filters and other enhancements.
3. Creating transitions between clips.
