SalNicols,
Camera one shows the aircraft floating by - no warm tires.
Camera two shows it doing something deeply bad, with at least one bounce ending with a firm impact on the nose and sparks/hot bits going backwards underneath, before it climbs away out of shot. I think you're right this camera perhaps shows perhaps two bounces, but there's low contrast.
Camera three shows nothing but the impact after the (I think second, perhaps third) bounce.
Camera five shows it all, but from a long way away. I don't see any clear sign of the first bounce there.
The overall picture shown by camera 5 does indeed seem reminiscent of 30 seconds into this video, at higher speed in a different - perhaps less robust - aircraft. I don't think the cause of the events shown here are in doubt
