Secret Robo FMV ending (playstation&DS versions)

[TheMage]

https://www.youtube.com/watch?v=eyUQjgtmMEc 4:37 in. Robo is the only one with a secret FMV ending?  Is this true? Is this listed on the Compendium somewhere? I don't recall ever seeing this ending or hearing about it and it's not listed here. https://www.chronocompendium.com/Term/Endings_(Chrono_Trigger).html

I don't believe he's talking about this either: https://www.youtube.com/watch?v=1Sr9bmSjTt8

As it doesn't show Robo at all.

Edit: Or is he saying Robo is the only one without an FMV ending? Robo and Magus are the only ones not shown in the video I just linked? I can't quite make out if he's saying with or without and the youtube captions option did not help.
