How can I add a zoom effect in Premiere Pro?

To add a zoom effect in Premiere Pro, you can use the "Scale" keyframe feature. First, place your video clip on the timeline. Then, go to the Effects Control panel, locate the "Scale" option, and set the initial scale percentage. Next, move the playhead to where you want the zoom to start, click the stopwatch icon next to "Scale" to create a keyframe, and adjust the scale percentage. Move the playhead to where you want the zoom to end, create another keyframe, and adjust the scale percentage again. Premiere Pro will automatically create a smooth zoom effect between the keyframes.
