A man who filmed himself abusing his girlfriend's 15-month-old son has been convicted of the child's murder.
Darren Newton, of Earby in Lancashire, had denied killing Charlie Hunt but admitted 12 counts of cruelty. The baby died of head injuries in November 2009.
The prosecution at Manchester Crown Court said Newton took videos on his phone for his pleasure and satisfaction.
The 32-year-old is due to be sentenced later.
The jury took 40 minutes to find the factory worker guilty of murder and one count of child cruelty. They cleared him of another charge of child cruelty.
Newton named the video clips crying, no toys in pen, ahhhh, squeezing toe in cot, two minutes of pain and Shivering no water.
The latter was taken on a November night when Charlie was naked in an empty bath.
In one graphic clip, titled Happy Slap which was filmed two weeks before Charlie died, Newton was seen to slap the child 13 times on the head as he screams and cries.
The boy's parents described Newton as evil and a monster.
