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.

Here are the various commands and functions of the Video Thumbnails pane:

You can show or hide the pane.

You can show or hide the video thumbnails.

You can display absolute frame numbers.

You can resize the thumbnails while preserving the aspect ratio by dragging the splitter bar.

The video track strip at the top of the Track pane has display fields for Video File Name, Start Time, Trim-In Time, Trim-Out Time, Duration, and Current Frame, as well as a toggle buttons to show/hide the thumbnails (without hiding the Video Thumbnails pane), and to show/hide frame numbers on individual frames. You can edit the Start Time, Trim-in Time, and Trim-Out Time fields.

SONAR saves the size and state of the Video Thumbnails pane on a per/project basis.

The Video Thumbnails pane zooms horizontally when you use the standard Track view commands for horizontal zooming. You control the height of the Video Thumbnails pane by dragging the splitter bar up or down that’s at the bottom of the Video Thumbnails pane.
