You have already said your output must be WMF.
If you want to output QuickTime files then convert to WMF, use Apple Animation or Apple None.
You can then use CompressionMaster makes very nice WMFs from QuickTime files.
Flip4Mac from TeleStream will allow you to export WMF directly from FinaCut.
You choose the amount of compression for the final output.
Higher Compresion = Smaller files, Lower Quality
