Hello Diane,
I just had the same problem with both exporting .aaf and .xml files out of FCP7 and trying to import them in AE CS5.
It just did not seem to find the footage on my external hard drive. Tried different projects hence different sequences> same problem.
So then I moved these footage files on to my internal HD, my Desktop to be precise. Relinked the footage in FCP and made the same steps in exporting both XML and AAF.
Now..AE is importing them just fine over Automatic Duck Pro import. Though this is not solving the problem, because I do not want to have hundreds of GB of video footage on my internal HD..
If anyone knows a solution for this, it be very welcome.
Thanks y’all..
Ruben
