Does this video show Jesus' blood leaking out of his 'tomb'?

VATICAN April 14: Conspiracy theorists claim the alleged tomb of Jesus is 'leaking blood' after a video appeared to show red liquid pooling on top of it.
Shaky footage shot at the Stone of Anointing in Jerusalem showed red patches on top of the slab as excited believers shouted in the background.
However, the claims were rubbished by sceptics who said it was a 'story that has literally no bloody evidence'.  
'The leaking blood phenomenon is usually explained by more mundane things,' Nigel Watson, author of Haynes UFO Investigations Manual, told MailOnline.
'Common examples include like damp causing rusty patches, condensation, or outright fraud.
'We need scientific evidence to support this rather than some shaky video footage, but for many people it is question of belief rather than examining the facts.'
Nicola Kanaan, from Galilee, claimed to have seen the 'blood' coming out of the tomb as she captured the footage.
However, Mr Watson also pointed out that the video was actually about four years old and had just been re-uploaded with fresh claims.  
'Either she suddenly travelled back in time to witness this, or she is being untruthful,' he said.
What is the 'tomb of Jesus'?
The Stone of Anointing is where, according to Christian tradition dating back to the 13th Century, Jesus' body was prepared for burial after he was crucified.
Various stones have occupied the site over the centuries, with the current one only in place since a reconstruction in 1810.
The wall behind the stone has blue balconies and tau cross-bearing red banners depicting the insignia of the Brotherhood of the Holy Sepulchre, named after the church the stone sits in.
A three-part mosaic along the wall depicts the anointing of Jesus' body, the Descent from the Cross, and the Burial of Jesus.
The stone is part of the Church of the Holy Sepulchre, one of holiest sites in Christendom that attracts thousands of pilgrims every year.
The church is believed to contain all the major sites of Jesus' crucifixion and resurrection, making it a magnet for Christians.
They include Golgotha, a hill where Jesus was crucified alongside two thieves, and the tomb where he was laid to rest and rose again from.
Little hard evidence exists that the locations are accurate because they were only vaguely described in the Bible.
The stone is inside the Church of the Holy Sepulchre, one of the holiest sites in Christianity where Jesus' body is believed to have been prepared for burial.
Social media users ranged from sceptical to total belief in their reactions to the video that began circulating earlier this week.
'The truth is in front of people and they just deny it,' one commented, while another dismissed it as 'this is just fake'.
