Lesson 12. Changing Motion Properties > Sizing, Positioning, and Cropping an Im...

Sizing, Positioning, and Cropping an Image

You can adjust a clip's size, position, and other parameters by entering numbers and dragging sliders in the Motion tab. In addition, there is an Image+Wireframe mode that helps you create motion effects directly on the image in the Canvas.

From the Sequences bin, open the Motion – Finished and Motion – Starting sequences. Play the Motion– Starting sequence.

This sequence contains the same clips you worked with in the previous exercise, as well as some of the speed and freeze-frame effects, but the clips are laid out differently on the tracks. The team member clips have been placed on the V2 track over their slow-motion racing shots.

Click the Motion – Finished sequence, and play it.

By changing motion parameters such as size, crop, and position, you can see mulTiple images on the screen at the same time. Also, some of the video clips in the sequence have opacity keyframes to fade the video in or out, and some have been color-corrected.

Click the Motion – Starting tab, and toggle off the Clip Overlays. Move the playhead into the second clip, DS intro, and double-click the clip to open it in the Viewer. Click the Motion tab.


Always position the playhead over the clip you opened in the Timeline so you can see both the Motion tab in the Viewer and the image in the Canvas as you make changes.

Drag the Scale slider to the right as far as possible and then left, looking at the image in the Canvas as you drag. Then enter 65 in the Scale percentage field.

With this clip sized less than 100%, you can see the clip beneath it on the V1 track. Notice there is a turquoise border around this clip because it is selected in the Timeline.

To reposition this clip to the left, click the Center crosshair button in the Motion tab, and move the cursor into the Canvas. Click the midpoint of the left turquoise border, but don't release the mouse. Drag right or left to make sure you can fully see the man's face and then release the mouse.

To crop the right portion of this image, click the disclosure triangle next to Crop to reveal the Crop controls. Drag the Right slider to the right to about 32.

In the Timeline, double-click the DS good ride clip to open it in the Viewer. If necessary, click the Motion tab. Enter 65 for the Scale percentage to match the previous clip.

To reposition this clip a different way, you will drag the clip's image in the Canvas.

In the Canvas, click the View pop-up and choose Image+Wireframe.


You can also choose View > Image+Wireframe, or press W with the Timeline or Canvas window active.

A large white X appears corner to corner over the image area, and a number appears at the center point, indicating the clip's track number. With this mode selected, you can position the clip manually by dragging it around in the Canvas image area.

Move the pointer into the Canvas over the DS good ride clip. When you see the Move pointer, drag the image, but don't release the mouse. Now hold down the Shift key and drag the image up and down and left and right.

The Shift key constrains your movements and helps you stay aligned with the clip to the left.


When you move your pointer over an image in the Canvas, there are several icons you might see, depending on the exact location of the pointer over the image's wireframe.

Move pointer in image area

While holding down Shift, drag the clip to the right until you see some black space or separation between the two clips, and release the mouse. Play the clips in the Timeline.

To ensure the outer edges of these two images will appear within a viewable area on home television monitors, click the Canvas View pop-up and choose Show Title Safe. Make any necessary adjustments, then toggle off this overlay.

The Title Safe overlay has two turquoise guidelines. The inner guideline is used to position text; the outer one indicates an “action safe” area. Any action you want the viewers to see should appear within the outer guideline.
