Recently I noticed that the stabilization media effect in my Sony Vegas Pro 11.0 (64 bit) (Build 701) installation has stopped working. I can't remember exactly when this problem arose, but now when I right click on a media clip and select "Media FX / Sony Stabilize" and try to stabilize, the render window pops up briefly, shows 0% on the progress bar, then closes immediately. Playing back the clip, the clip appears unchanged. No matter which settings I select, the render window just pops up then disappears. I've reinstalled Vegas twice now, even trying the 32-bit version to see if it would make a difference. Nothing. Can't figure out what's wrong. Any suggestions as to how I may remedy this issue? Thanks in advance!
