The background is almost done, now that you've created the grid and fixed up the foreground car. To finish it, you'll add another version of the Saleen_Car_07 footage that you'll make play at a slightly different rate than the original. Do the following: 1. | Go to time 3;00 in the Master composition's Timeline, and add Saleen_Car_07.avi from the Project window to the Timeline at the bottom of the layer stack. | 2. | Select the new layer, and choose Layer > Time Stretch. Set the Stretch Factor New Duration to 7;00 in the resulting dialog, and click OK. As a result, the layer plays at a slower rate than the same footage that appears in the Car composition. | 3. | Set the layer's Scale to 200, 200%. | 4. | Apply Effect > Blur & Sharpen > Fast Blur to the Saleen_Car_07 layer, and set the effect's Blurriness to 10. | 5. | To fade in the layer, add a 0% Opacity keyframe at time 3;00 and a 100% Opacity keyframe at time 5;00. | 6. | To fade out the layer, change its Opacity to 50% at time 8;00 and 0% at time 9;00. | |
