FYI in my latest update I've made all the SAC FMV related options in Harmony be tied to the corresponding options in SAC to avoid any confusion (as in, setting them in SAC will also set them in Harmony if they're both downloaded and active). This does mean the settings will need to be set in SAC rather than Harmony, but I did add a new option in SAC to accommodate the custom version of the ending you did to compensate.
