Video Playback, Import, and Export

these changes permanent (and thereby reduce the load on your CPU)

by using the File-Export Video command, and then re-importing the

file.

• Playing videos at a resolution (video size) of 320x240 is usually a high

enough resolution to monitor the video while you’re composing a

soundtrack. You can still choose to stretch the video to full screen at

this resolution. You set the video size on the Render Quality tab of the

Video Properties dialog. Using a higher resolution can bog down your

computer if you’re processing audio tracks at the same time.

Using the Video Thumbnails Pane

At the top of the Track view in SONAR is the Video Thumbnails pane, which

displays individual frames of your video at certain time intervals of your

project. The time interval between displayed frames is determined by the

zoom level you choose. If you zoom in far enough, you can view each

individual frame of your video.

Note 1: if you’re playing back a highly compressed movie (not many

keyframes in the file), it can take about a minute to redraw video thumbnails

when you’re playing the movie or resizing a window.

Note 2: some Windows Media videos do not report their frame rate to

SONAR. SONAR can play these files, but cannot create thumbnails from

them, so no thumbnails appear in the thumbnail pane.
