Exporting Uncompressed AVI from FCP - Best Way?

Hi,

I use a program at work on a windows computer, called Blaze (made by Click Effects) which runs our video scoreboards here. The only video format that the software will accept for video, is Uncompressed AVI.

Since I use a mac for all of my design work, I need to be able to export Uncompressed AVI from my software on the mac, or at least a way to export and then convert to the right format that I need. I used to be able to export using other software, but then would need to convert the file with other programs to get them to work, but since then the programs have changed and I am unable to do this anymore.

Is it possible to get Uncompressed AVI from FCP, or will I need other programs to convert this for me?

Any help would be appreciated. Thanks
