Preparing and Importing Source Clips
Capturing video for offline and online editing
Depending on the level of quality you require and the capabilities of your equipment, you
can use Premiere for either online or offline editing. The settings you specify for capture are
affected by whether you will edit the program offline or online.
About online editing
Online editing
is the practice of doing all editing (including the rough cut) on the same
computer that will produce the final cut. Previously, online editing had to be done on
expensive high-end workstations designed to meet the picture quality and data processing
requirements of broadcast-quality video. Editors with high-end requirements who could not
afford a suitable online system had to rent time at a production facility that owned one.
As personal computers have become faster, online editing has become practical for a wider
range of productions. With high-end personal computers, online editing is practical for
broadcast television or motion-picture film productions.
For online editing, you’ll capture clips once at the highest level of quality your computer
and peripherals can handle.
Note:
When you edit Digital Video (DV) format clips, all editing is online. At the time this guide
was written, the DV format did not allow creation of a low-resolution version at import time.
However, DV compression makes standard DV manageable on many systems.
About offline editing
In
offline editing
, you edit video using lower-quality copies of the original clips and
produce the final version on a high-end system. Offline editing was developed to save
money by editing in a less expensive facility. Although offline editing can be as simple as
writing down time points for scenes while watching them on a VCR, it is increasingly done
using personal computers and Premiere. Once you have completed the offline edit in
Premiere, you create a table of scene sequences called an
edit decision list,
or EDL. You then
move the EDL to an
edit controller
on a high-end system,
which applies the sequence
worked out in Premiere to the original high-quality clips. In this way, the editing work
done on the less-expensive workstation is used to create the final cut on the more
expensive, higher-quality workstation.
