Stabilization- Max Zoom slider not showing up.
I'm having a problem with the stabilization all of a sudden. I did an analyze. The amount of shake isn't terrible but it's there. There are no squiggly lines in the clip I'm trying to stabilize. As you can see in the screenshot that it allows me to click the "Smooth clip motion" but the slider is not there for zoom. Any ideas why this is happening all of a sudden? It happens on all clips in this event. The entire event was analyzed after importing.
Thanks!
