Photo Problems iMovie HD's photo features are, in general, a delight--and they let you get mileage out of iMovie even if you don't own a camcorder. But you may encounter some rough edges. Photo Problems Can't Change the Duration of a Still Photo iMovie distinguishes between still photos and still frames, of the sort that you capture using the EditCreate Still Frame command. Moreover, it differentiates between photos that exhibit the Ken Burns effect and those that don't. It's so complicated, you practically need a cheat sheet--and here it is. · To change the duration of a Ken Burnsized photo (imported from iPhoto or from the hard drive), click the clip and then use the Duration slider (or Duration box) in the Photos palette. Click Update. · To change the duration of a still frame, double-click it. Change the duration in the Clip Info box. · To change the duration of a non­Ken Burnsized photo, use either method: the Duration slider in the Photos palette, or the Clip Info box. Ken Burns Accelerates Too Much When the Ken Burns effect zooms in on an image, the clip sometimes appears to accelerate. There's a pause at the beginning of the clip, then the zooming goes faster and faster, all the way to the end. Most of the time, you probably want, if anything, a deceleration, so that the zoom comes to rest gently at the end of the magnifcation. You can't eliminate this acceleration, but you can minimize it. These solutions rely on eliminating the pause at the start of the clip, which makes the zooming look smoother: · Zoom less. A gentle zoom is usually better anyway. · Add a Cross Dissolve transition before the Ken Burns clip; the transition covers the pause at the beginning. (The length of the pause depends on the duration of the clip and amount of zoom.) · Set the Ken Burns duration a second or two longer than you actually need. Then, after the clip is fnished rendering, crop out the frst part of the clip by dragging its left edge to the right. Ken Burns Zoom Always Shows 1.00 When the Ken Burns checkbox is turned off, it can look like the zoom is stuck on 1.00. You'll see this situation when two conditions exist: First, the Ken Burns checkbox is turned off when you import a photo; second, the Ken Burns zoom setting is greater than 1.00. For this example, suppose it's 1.48. appendixb:troubleshooting 483
