Edius X is no different than Edius 9 in terms of its plug-in interface, so it remains only half-capable of 10-bit support.
Which means it is still not sufficient to satisfy the requirements of Neat Video to the plug-in interface.
In other words, there are no changes in this part of Edius, unfortunately.
Unfortunately no, the situation has not changed much in Edius 11. The traditional plug-in interface of Edius has not changed in Edius 11. The new OFX interface is not fully implemented, so some crucial features are still missing, making it impossible for Neat Video OFX to fully work.
We hope that the OFX interface will be improved in Edius over time.
