A video production project will take a significant amount of time to prepare and also edit because it is common practice in the business to shoot hours of footage and extract only a few minutes.
For instance, you could work on a video interview with an important subject. When you work on that type of production, you will see that people will make pauses or interrupt the discussion in several other ways.
In the end, you will have unedited and raw footage with half an hour of material, which you have to cut and edit until it gets to only 10 minutes.
That is when you will need to use tools to cut, edit, and reorder video footage. In Blender, you will find all those options in the Video Sequencer. Since you already know how to use and get footage to the sequencer, we can move forward and edit video footage.
