The rendering time depends on your system’s resources and the complexity of the segment.
Play a sequence from start to finish
❖ In the Program Monitor, click the Play In To Out button.
Play a sequence with preroll and postroll
You can preview a sequence with preroll and postroll pauses of lengths you can determine with settings in general
preferences.
1 Click anywhere in the timeline to make the sequence active.
2 Press Shift+Space.
Set the duration for sequence preroll and postroll
You can set the length of preroll and postroll for sequence previews in the General pane of the Preferences dialog
box. These controls shouldn’t be confused with the Preroll setting in the Device Control pane of the Preferences
dialog box which affects the control of external devices such as VTRs and camcorders.
1 Select Edit > Preferences > General.
2 In the Preroll and Postroll fields, type in the number of seconds for each.
3 Click OK.
Disable rendered previews
To increase editing performance on larger projects, disable rendered previews. Disabling these previews prevents
Premiere from writing or reading rendered preview files on disk, letting the application edit in real time as fast as
system speed allows. When rendered previews are disabled, the red and green render indicators in the time ruler are
replaced with a blank white bar. When these previews are re-enabled, existing preview files are restored if no
changes have occurred in related sections of the sequence.
❖ In the upper-left corner of the Timeline panel, click the Enable Or Disable Previews button .
Scroll the Timeline panel during preview
You can set an option to automatically scroll the timeline when a sequence is wider than the visible timeline.
1 Choose Edit > Preferences > General (Windows) or Premiere Pro > Preferences > General (Mac OS).
2 Choose an option from the Timeline panel Scrolling menu:
No Scroll Timeline panel doesn’t scroll.
Page Scroll Timeline panel scrolls the visible section of the timeline a page at a time.
Smooth Scroll Current-time indicator stays in the center of the visible timeline. This is the option set by default.
Preview on a television monitor
You can display the sequence on any monitor connected to your computer. Previewing on a television monitor
requires video hardware that provides an appropriate video port for the monitor. Some video cards and operating
system software products support a television monitor independent of the computer desktop. Others support a
second computer monitor that is contiguous with the computer desktop so that it can also function as additional
space for the application. See the documentation that came with your video card and operating system.
