Scrolling a form

I am trying to find another way to scroll a really long form without using the scrollpane component.

Here’s the scenario, I have an interface that has video playing and when a link is clicked I have a application form pop in to another section of this interface. Using the scrollpane is causing the video to lag, with the longest form like 2 seconds, so I am trying to find another way of going about this. Any help with this issue would be greatly appreciated.
