Learn the Jaw-dropping ZOOM-Slide Effect in Premiere Pro!
By using the transform and crop effects together, you can control the outer image frame (containing frame) size and the magnification of the image within the frame independently of each other.
Additionally, keyframes allow you to precisely control the start and end points of each effect, which means you can easily produce a smooth blending together of the two zooming techniques.
You can also crop any of the four sides of the image and change the outer frame position, all by using keyframes... allowing you to create dynamically controlled, versatile zooming effects.
