OK, pitiful first attempt

the script will terminate with a message to manually set the endframe higher than the frames in the import file, dont know how to automate that.
the translate values will need to be scaled from whatever units to Poser units , thats pretty easy. 
it needs a dialog for selecting the input file - not hard but havent done it :)
uses Main Camera as the camera to animate
does not use the zoom info yet - thats also not hard to add.

Theres a lot in the file I dont understand , I have just grabbed the camera animation curve.
