Capture can be as simple as taking a photo, or shooting a single video clip.
It can be as complex as setting up multiple cameras with many audio channels from an array of microphones feeding a a multi-channel digital audio mixing unit.
All the capture for a given video editing sequence might come from many different sources at different times – the idea of the “B-roll” for film footage is a good example.
“Non-linear” editing software allows “importing” and pulling all of these pieces together, manipulating them, and assembling them in wonderfully creative ways – all without “cutting” any of the original material! Color grading for the right tone ambiance, consistency of color between clips and between cameras is also carried out here in this ‘post-production’ process – a work of hours, days, or weeks.
