After Effects Stabilize Motion slowing down
 

Ive noticed that when running the stabilize motion the process slows down over time as its processing frames. If you stop and restart the process, it speeds up again. Anyone observed this, and is there a setting or setup that could be causing the slowdown? Currently, Im monitoring the process and starting/stopping it to keep the speed up.

I've been using the trial version and I gotta admit this program is a dog. It uses 4 gigs of ram to combine a jpeg with a 1920x1080x30p xdcam ex clip that is motion tracked. The clip was only 15 seconds long! Plus is was going to be 44 minutes to render it. Forget that! I can't use a program that uses resources like this.
