Has there been any luck finding a solution?
I’m currently having the same problem trying to import a FCP 7 XML to After Effects CS6 and experiencing a crash each time. I’ve tried removing all filters and exporting different version of the XML. My media in FCP is all uniform (ProRes 422) and there are 5 clips stacked.
I don’t have this problem with other projects but every XML I export seems to crash AE regardless of which sequence I’m exporting.
