Maximizing Performance
Setting up a virtual clip as a separate project
Including a complex virtual clip in the Timeline increases the calculations Premiere must
perform to create a preview file. Try exporting the virtual clip as a video file using a lossless
compressor and importing the resulting video file into the main project. Previewing will be
faster because all the effects in the sequence will already be calculated into the finished frames.
Maintaining edited projects
After you have worked in a project for a while, you may accumulate clips that you aren’t using
or find that you captured much more footage than you actually use in the video program.
Premiere provides ways to remove unused clips and clip frames from a project; see “Removing
unused frames from source clips” on page 69.
You can also generate a batch list to recapture the frames of only those source clips which you
are actually using in the video program. This allows you to store smaller clips on your hard disk.
See “Creating a batch list to redigitize project clips” on page 104.
You can export a list of the files used in the project. See “Creating a text list of project or library
files” on page 83.
