A Steadicam doesn't 'bob up and down'! The clue is in the name.

I guess they managed to fix whatever issue you think they had on a Sunday morning within the space of an hour and end up with a very smooth closing shot from the same EF camera they'd used at the start. Blimey, that engineer must have been on speed dial and close by.

Im thinking it was possibly a hand held gimbal rather than a full sized steadicam, DJI Ronan maybe.

More likely a DJI Ronin. The DJI Ronan makes everything look like life is a rollercoaster.
