I have a G5 (PPC) iMac, and I am have just bought a new intel 17" version.

I currently run FCP 5.0 on the PPC. If upgrade and I instal 5.1 (.4) on my iMac intel can I use all my old plugins I had on my G5? I have heard the plugs did not work on the intel. I want the maximum speed from FCP on the intel so I want the upgrade. Will my Plugs still work?

You may have issues with some third party plug-ins, but native plug-ins seem to work fine. I just promoted an old v4.5 project to v5.1.4 on Intel today and all of the native effects applied worked fine.

Yes that is my worry- the 3rd party plugs. I have Natress and MB filters and some freebies from CHV. Good to hear the nativies work well! Any body work with the 3rd parties?

Graeme Nattress' plug-ins should work fine on Intel. CHV plugins should also be fine.
Anything built in FXbuilder should work, because the plug-in is only referencing the application's resources.

I'm not certain about Magic Bullet because of the way they serialize to the actual serial of the FCP install. You may want to check their support site. You will get a brand new serial number when you order the Universal upgrade.

Just make sure you copy and backup your plug-ins folder before you upgrade.

Boris FX transitions WILL work in FCP 5.1.1 BUT, will NOT work in 5.1.2 and up. Boris says that Apple will address this problem in their next major upgrade. Until then, there is a "work around" posted on Boris' website.
