How to bring a SketchUp Animation into After Effects
Not sure on the AVI but kept searching and found http://sketchucation.com/forums/viewtopic.php?f=11&amp;t=18827


  What OS are you using?
  
  Vista 64 bit has codec issues, so if it is indeed a Vista 64 bit you need to export as a series of images (which is best anyway) and compile it in after effects.


I'm on Windows 7 so don't know why it was an issue to begin with but did the Export as Images instead. Then did a simple Import (Ctrl+I) which detected the jpeg sequence and that worked perfectly. Smaller file size then the AVI SketchUp exported too.
