In Final Cut Pro 6.0.2, if you open a project that was created in an earlier version of Final Cut Pro 6, Master Templates used in the project may appear to be scaled differently than expected.
For example, this can occur if your project uses a High Definition format Master Template in a Standard Definition sequence.
In such cases, you can resize the Master Template instances in your project so that they are scaled correctly. Alternately, you may wish to replace the Master Templates used in your project.
