Adobe Premiere Pro CS3 is the first version of Premiere to be released for Mac since 6.5 in 2002. It’s got an odd problem, though. Unlike previous Mac versions of Premiere–or any other Adobe product that I can think of, actually–it refuses to import Windows Premiere projects from earlier versions!

If your project file was made in Windows Premiere Pro 1.0 or later, there’s a relatively painless solution. Open the file in a text editor and change the tag that reads Project Version="15"…

…to Project Version="19".

You should now be able to open it in Mac Premiere Pro CS3.

If your project file was made in Windows Premiere 6.5 or earlier, unfortunately, you have two less attractive options. In order of preference:

Option 1. If you have a copy of Windows Premiere Pro 1.0 or later, use that to open and save the project. Then perform the text edit trick described above. This method should work for all affected project files.

Option 2. If you have a corresponding Mac Premiere version 6.5 or earlier, you can try using that to open and save the project. Then open it in Mac Premiere Pro CS3 directly. This method is less reliable, but is worth a try if you have an appropriate version handy.
