I’ve seen a significant amount of confusion about this, so I thought that it would be good to make this explicit statement:
You do not need new versions of plug-ins for Premiere Pro CS5.5. Plug-ins that work with Premiere Pro CS5 should work with Premiere Pro CS5.5.
I think that some of this confusion came from the need to get new versions of plug-ins when we advanced from Premiere Pro CS4 to Premiere Pro CS5. That was necessary because of the move from a 32-bit application to a 64-bit application. There is no such fundamental infrastructure change from Premiere Pro CS5 to Premiere Pro CS5.5.
You do need to make sure that the plug-ins are installed where Premiere Pro CS5.5 is looking for them. Premiere Pro CS5.5 has its own plug-ins folder, and it doesn’t look in the CS5 plug-ins folder, unless you tell it to do so (more on that in a bit). So, be sure to install the plug-ins in the right place.
By default, the plug-ins folder is in the following location:
- (Windows) Program Files\Adobe\Adobe Premiere Pro CS5.5\Support Files\Plug-ins
- (Mac OS) Applications/Adobe Premiere Pro CS5.5/Plug-ins
Premiere Pro also loads plug-ins from a MediaCore folder, which is intended to hold plug-ins shared between After Effects and Premiere Pro. Some third-party plug-in installers install their plug-ins in this folder. You should follow the instructions for these third-party plug-ins regarding how to install plug-ins for Premiere Pro CS5.5.
Here are links to the sites of some third-party plug-in providers, where they give instructions:
Tip: You can have an alias/shortcut in your CS5.5 plug-ins folder that points to the CS5 plug-ins folder. That way, when Premiere Pro is scanning the CS5.5 plug-ins folder for plug-ins to load, it’ll follow that alias/shortcut to the CS5 plug-ins folder and load plug-ins from there. Be careful if you decide to go this route, since it’s easy to point to duplicate versions this way. I keep my third-party plug-ins that are not installed with Premiere Pro in a separate “after-market” folder in my CS5 Plug-ins folder, and my alias/shortcut in my CS5.5 Plug-ins folder just points to that.
Michele Yamazaki show how to do it here.
I didn’t find concise instructions for creating a shortcut to a directory on Windows, but the gist is this: Right-click a directory, and choose Copy; in the destination location, right-click, and choose Paste Shortcut.
All of this applies to After Effects, as well.
