Hi Pascal,
Upon rereading the title of your message, I noticed that you are using a Mac. Unfortunately at this time we do not have a solution for Boris RED users in the Adobe Premiere Pro CS3 host on the Mac. I believe it should work on Windows, although if you’re on a Mac that won’t help you all that much.
Premiere Pro CS3 is new to the Mac and there are many integration issues that have to be worked through before RED 4 will actually function as expected. When we have an update of RED 4 that works within this PP CS3 on the Mac we’ll post a message on the web site and also on the Cow forum.
Meanwhile please know that you can use the BCC 5 filters in Premiere Pro CS3 on the Mac.
I hope this helps.
Cheers,
Peter.
