No, but the techniques are getting better (deep fake) ... though I doubt Pablo would have access to that level of technology.
The only suspicion that it might be photoshopped is the source ... Pablo.
I mean, they were promoting those OBVIOUSLY photoshopped pictures of Moran with Cardinal Slipijy
Yes, but logically that made sense. He wanted (or "needed") to establish Ambrose's legitimacy as a bishop, so HE could benefit (getting consecrated, having his "seminarians" ordained, etc.) Ambrose was his only option at the time.
But as you yourself said, there are plenty of "garage bishops" out there for ANY priest to get himself consecrated, if they reach that low point in their spiritual life. So it's most likely Fr. Pfeiffer eventually found and convinced one or two of these.
But something like this, he'd want to broadcast the REAL consecration ceremony to make sure everyone knows he's a "valid bishop". Nevermind Fr. Pfeiffer's spiritual problems brought up in the past by Fr. Voigt, the complete lack of order or discipline at the seminary, or the demonic influence of Pablo. THOSE are the real issues with Fr. P.
The problems with this scene happened when he approached those bishop(s) for consecration -- not the scene of the consecration itself.
What I'm trying to say is, when you can get shifty bishops to consecrate you bishop, you don't need shifty photoshop fakes.The problem in this case is Father resorting to shifty bishops who will consecrate any priest.
