Premiere Pro CC Digital Classroom
Lesson 1: Understanding Digital Video
What you'll learn in this lesson:
- To understand the difference between editing and delivery formats
- To understand the difference between high-definition and standard-definition video formats
- To understand the digital post-production workflow
Before you begin editing in Premiere Pro, it is beneficial to become familiar with some of the concepts and principles that define the art and craft of video editing.
You will not need any files for this lesson.
Understanding digital Non-Linear Editing
When you watch a video or film, what you are actually watching is a series of still images displayed sequentially at a high rate of speed. Each image, called a frame, is displayed on screen for a very short period of time (anywhere between 1/24th to 1/30th of a second), creating the illusion of continuous motion. In the past, the only way to edit film or video was using a linear system. That is, an editor had to advance a film reel or tape to a specific part and cut or copy from that point forward. If she or he then wanted to edit another part of the footage, they had to advance the entire reel or tape to a new location and start again. It could be a very tedious and time–comsuming process. Adobe Premiere Pro is an example of a digital NLE (Non-Linear Editor): it gives you direct and immediate access to any frame in a digital video clip at any time. In an NLE process, you use computer data instead of a physical linear medium, such as film or tape, and you can jump back and forth along your timeline at any point in the editing process. Unlike traditional graphic image processes, this is a non-destructive process because the original source footage is never lost or altered. The media links that you import or capture in Premiere Pro are only references to the original footage stored on your hard drive.
The video and audio footage that you edit in Premiere Pro can be digitized from an analog source, such as a VHS or cassette tape, or recorded directly to a digital format, as is the case with modern video cameras as well as other hard drive and compact flash-based recording devices.
Understanding video settings
In Premiere Pro, you generally work by building sequences to match the standards of the media you are going to work with instead of the intended output. There are many types of video files you can work with in Premiere Pro. The various formats, aspects ratios, codecs, and other settings used to describe video files will be explained in this book. The following terms will help you:
Dimensions : specifies the pixel dimensions of a video file; in other words, the number of pixels horizontally and vertically that compose an image or video frame. This value is usually written as a pair of numbers separated by an X, where the first number is the horizontal value and the second represents the vertical; for example, 720 × 480. Pixel is a conjunction of the words "picture" and "element" and is the smallest individual component in a digital image.
Frame rate : specifies the number of individual images that compose each second of video. Frame rate is displayed as a value of fps (frames per second).
Pixel Aspect Ratio : specifies the shape of the pixels that compose an image. Pixels are the smallest part of a digital image and different display devices (televisions, computer monitors, etc.) have pixels with different horizontal and vertical proportions.
Editing vs. delivery formats
While working through the many lessons presented in this text you are going to encounter many new concepts and terms, especially when you are dealing with video footage. When working with video in Premiere Pro you will encounter many diffe
