encoded pixels 720 x 576 to display at 1025 x 576

hi, how do I encode pixels 720 x 576 to display at 1025 x 576 using final cut pro 7? I can do this with QT pro 7 but I need to create a time code. see QT movie properties below

Create a new project, set the controls for your desired output size, drop your clips into the empty project and scale them up. You're going to crop something because you're expanding the width by a factor of 1.42 but you're not changing the vertical dimension. Export.

That answers your question but that may not be what your'e really asking. Why do you want do this and why aren't you just using the simple and direct solution?
