For some reason have to buy 7tox ,unfortunately…
Fcp 7’s XML file output from 7toX its doesn’t work on FCPX.
No matter what i save the file first .
An update yesterday have same crash on it.
After talk with the FCPX group
Find out Resolve can make it done.
Import 7’s XML file to Resolve then export a FCPXML 1.4 format ,done
just few FX can’t read from Resolve such as transition
Seem like waste some on 7toX .
but finally ,headache no more
