Optimizing the Video Preview window
Timing and synchronization are critical aspects of any multimedia production. Because complex multimedia projects are
challenging for any computer, a number of tools are provided to maintain real-time playback even though the computer may not
be able to process the data quickly enough.
Adjusting preview quality and resolution
You can adjust the resolution of the Video Preview window and the quality of the preview rendering in order to improve playback.
Lower-resolution previews are less clear but allow more frames to be displayed per second. This may be particularly important with
projects that use overlays, transitions, and effects. Click the Preview Quality button and choose a setting from the menu to change
the quality and resolution for rendering your video preview.
