• Instant Playback allows you to quickly preview changes in your project
without the need to create a temporary preview file, however, playback may
be jerky depending on your computer resources.
• High Quality Playback renders your project as a temporary preview file
then plays this preview file. Playback is smoother in High Quality Playback
mode, but rendering your project for the first time in this mode may take a
long time to complete depending on the size of your project and computer
resources.
Note: When Perform non-square pixel rendering is selected in the Project
Options dialog box (opened from Project Properties dialog box), Instant Playback
performance may be affected if computer resources are insufficient.
In High Quality Playback mode, VideoStudio uses SmartRender technology which
renders only the changes you made such as transitions, titles and effects, and
eliminates re-rendering the entire project. SmartRender saves time when
generating previews.
Setting a preview range
For faster previews, you may choose to play only a
part of your project. The selected range of frames to
preview is referred to as the preview range, and it
is marked as a red bar in the Ruler Panel.
To play the preview area only:
1. Use the Trim Handles or the Mark-in/out
buttons to select the preview range.
The Preview range mark-in and Preview
range mark-out timecodes will then be displayed
in the Options Panel.
2. To preview the selected range, select what you
want to preview (Project or Clip), then click
Play. To preview the entire clip, hold [Shift], then
click Play.
