Hi Erick,
Mike Rubin from Tiffen here. I’m Director of Marketing so I preface everything with saying I know my products but I’m not a technical expert or professional editor.
If you are using version 3 then the solution would be to save your Setup File form the Dfx interface in FCP from and then import the Setup File into Adobe Premiere using the Dfx interface.
I don’t know enough about the translation from FCP to Premiere (other than watching some videos) so I am not sure what would happen with key-framing and levels of effects applied.
Please feel free to contact support: https://www.tiffensoftware.com/support
Also you can email me but I will have to pass it on to our support team: mrubin (at) tiffen (dot) com
Best,
Michael Rubin
