Jackpot ladies, jackpot. I am the one who started this thread, and here is my conclusion, which pretty much lines up with Andrew's findings. When I had issues with the jumpy pan & zoom effects in PD7, I decided to go and use my older Core 2 Duo. I never got around to posting my findings until now. Basically, everything was very smooth. At first I thought I would just install the basic PD7 without any upgrades, and that would do the trick. But since I started my project with the upgraded build of PD7, it forced me to take the update again in order to load up my project. So I did, and honetly, left out the pan & zoom effect until the morning of my event. I decided on a whim to give it a last whirl and see if I added one pan & zoom effect at a time to one photo at a time, and see what would happen. And kept adding until I was able to batch add the effect to every shot. And it played back and rendered super smooth on the Core 2 Duo.
So Cyberlink, if you guys are reading this, which I sure hope you are, you need to test the effects against the family of Quad cores. More specifically, add about 100+ shots, then transitions, then music, and once you have all that together, try to add the pan & zoom effect to all the shots and then render. You will instantly notice the jerky, choppy movement while it pans and zooms....
On a side note, the transitions never gave me an issue, but perhaps that is expected.
Thanks everyone for working thru this issue with some of us. I do hope Cyberlink come out with a patch for this issue...
