Just updated Premiere via Cloud a few days ago. For months I have been capturing video from SONY Z7U via firewire using a firewire 800 to TB adapter on iMac. No problems... works great. Now, since recent update of Premeire... SERIOUS ERROR warning comes up when attempting to play tape from capture window. Same settings... haven't changed a thing. Can I go back to my previous version soemhow? What is the problem?
