Can Video Enhance AI be run on Log files (ProRes 4444XQ) before Color Correction?

Hi all,

 I have 2 questions about the Video Enhance AI **Workflow**: 
  1. Can the Program be used on ProRes 4444 XQ Log Files ? And, if so, should settings be any different?

  2. In terms of the Workflow: Should I first do a Preliminary Color Grade, and then run Video Enhance AI, or the other way around?

    Thanks in advance for your reply.
