A Digital Video Primer
Adobe Premiere Pro provides built-in vectorscope, waveform, YCbCr Parade, and RGB Parade
monitors to provide accurate representations of chrominance and luminance levels. With these
tools, you can see whether clips share a common color spectrum and make sure that your color
adjustments fall within broadcast limits. For color adjustments, Adobe Premiere Pro provides
a number of options ranging from the Fast Color Corrector, for simple adjustments that render
in real time, to the ree Way Color Corrector, which provides control over hue, saturation, and
luminance for highlights, midtones, and shadows. Many of the color correction modules also
feature optional secondary color correction, which allows you to limit the range of the image
that is corrected. Secondary color correction can be used for ne adjustments or for achieving
special eects.
Use built-in color monitors to see if clips meet color broadcast standards.
Merging creativity and productivity
One of the more time-consuming aspects of editing video on a desktop has been waiting for
productions to render before you can see how eects, transitions, and other edit choices look. As
computers have become faster, video editing systems have introduced real-time previewing, but
usually with articial boundaries that limit their eectiveness. Adobe Premiere Pro enables you
to see exactly how your video will look without waiting for sequences to render.
Whether you’re making on-the-y changes for a client or preparing to export your nal produc-
tion, you’ll deliver results quickly. Adobe Premiere Pro plays back full-resolution frames, including
titles, transitions, eects, motion paths, and color correction on two channels, in real time with
no additional hardware support. Because it’s fast and ecient to preview editing decisions as you
make them, you can experiment more freely. You could, for example, try dierent settings for
the eects you’re creating, and then play back each combination to check the results and decide
which one works best. You can also view scenes played back in real time on an external NTSC
or PAL video monitor, a time win when you need to check how a work in progress will look on a
nal viewing device.
Note: e real-time editing experience is designed to take advantage of Pentium 4 systems, 3 GHz
and faster. Playback frame rates and quality degrade gracefully on less powerful systems.
WHAT IS REALTIME EDITING?
Previewing involves rendering (displaying) the frames
of a sequence for playback. Sequences that consist of
cuts between single tracks of video and audio render
quickly, whereas sequences that include layered
video and audio and complex eects require more
processing time.
Rendering: Desktop software used to (some still
does) make you wait while it rendered. Sometimes,
rendering an eect on a desktop system would take
minutes or even hours, which would slow production
to a crawl. If you wanted to generate results in real
time you had to purchase and equip your system with
a real-time video card that was compatible with your
software.
Background rendering: Background rendering still
requires you to wait before you can preview your
work. You can move onto something else while your
adjustments are rendering, but if the next thing
you want to do is dependent on the results, you’re
no better o. In eect, background rendering is like
being able to do something else while your dinner
cooks, but not being able to taste the food until it’s
completely done.
Real-time software: Real-time software (such as
Adobe Premiere Pro) oers you a better option,
one that’s more supportive of your creativity, while
promoting your productivity. The Real Time Preview
capability in Adobe Premiere Pro renders the frames
of the sequence on the y, so that in most cases,
previewing simply involves playing the sequence
using any of the controls in the Program view or
Timeline. When Adobe Premiere Pro can’t achieve
the sequence’s full frame rate, you have the choice of
playing the segment right away at a reduced quality
and frame rate, or waiting to render a preview le
that can play at the full frame rate. Sequences that
have been rendered at full frame rate for previewing
need not be rerendered for export. Real Time Preview
supports all Adobe Premiere Pro eects, transitions,
transparencies, motion settings, and titles.
Real-time hardware: Real-time hardware shunts
the processor-intensive work of rendering from the
CPU to a specialized processor on a video card. Most
real-time cards can handle the most common types
of eects, such as transitions and titles; more costly
cards can handle a much wider array of eects and
other techniques, even the capability to y your video
around in 3D, in real time.
