IS THIS THE APPARITION OF A GHOSTLY PRINCESS?

Leeds Castle Kent

 Recently I discovered this clip on Youtube and purportedly shows the apparition of what appears to be a small child which was caught on camera during an investigation at Leeds Castle, Kent.
The poster believes this to be the ghost of  Princess Caroline - King Henry XIII`s daughter who died at the age of 13 months some 400 odd years ago.
Whether this is a royal Princess or not, it does show something akin to a child.
The camcorder had been left to run remotely for a period of time when the capture was made.

                                             The apparition starts from 1:46
