Using Wireframes

Enabling Image+Wireframe mode in the Canvas or the Viewer activates a wireframe overlay that appears on your clip image. You must be in Image+Wireframe mode to graphically manipulate a clip's motion properties in the Canvas or the Viewer.

The elements of the wireframe aren't just indicators; they're also controls you can use to manipulate the size, shape, and position of your clip's image. Select the appropriate tool from the Tool palette; then drag a handle on the clip's wireframe.

Figure 15.6 offers a key to wireframe handles and tools.

Tip

While you work in Image+Wireframe mode, note that the selected track's number appears just above the clip's center point. The track number helps you remember which layer you've selected. If you're working on an effects sequence with many layered elements, that's a big help.
