You could also try using a single camera and moving it between the two positions. I do this for aim-down-sights by controlling the length of the boom (SpringArmComponent). It’s simple and it works really well.
Note that “Position” in the Timeline is a single float track going from 1 to 0 over 0.25s. For a more complex motion, you could use a vector track instead of the float track. It’s more complicated but still the simplest solution IMO. Also, CameraTrackLength is determined by subtracting AimingViewArmLength from the default boom length.
