System information

n You'll need to choose a rendering template that inserts pulldown fields to create a standard
DV file if your project properties are set to 24p or if you selected the Allow pulldown removal
when opening 24p DVcheck box on the General tab of the Preferences dialog. Use the NTSC
DV 24p (inserting 2-3-3-2 pulldown) template if you intend to use the file on the Vegas Pro
timeline.
If you cleared the Allow pulldown removal when opening 24p DV check box before adding
your media and your project properties are not set to 24p, your 24p video is read as 29.97
fps interlaced video (60i), so you can choose whichever NTSC DV or PAL DV template suits
your project requirements.
4. Click the OK button. The rendering process begins and a progress box appears. When completed, a
bar appears at the top of the timeline to indicate each rendered section.
Each prerendered section will consist of no more than 300 frames (approximately 40 megabytes).
Because selective prerendering creates multiple files, minor editing on the timeline will not invalidate
all of your prerendered video—only the sections you modify will need to be rerendered.
Cleaning Up Prerendered Video
From the Tools menu, choose Clean Up Prerendered Video to delete the temporary files created as a result
of using the Selectively Prerender Video command. For more information, see "Selectively Prerender
Video" on page 478.
Use the Clean Up Prerendered Video dialog to specify which prerendered files should be deleted: you can
remove only inactive files (files for media that is no longer used on the timeline), all prerendered files, or all
prerendered files within a time selection.
