Fake video about Azov crucifying a POW

A disturbing (and disputed) video has been broadcast by the Russian news agency LifeNews which reportedly shows Ukrainian volunteers from the Azov Battalion (which now calls itself Azov Regiment) taping a POW to a cross, driving nails through his hands, and then setting him on fire.  The video starts with a group of men, some of whom are armed, surrounding a man who is on the ground. One of the armed men makes a prepared speech in what sounds like Ukrainian. The speech is stilted and monotone, like it was memorized, or even read from cue cards which may be out of frame -- a familiar trope of contemporary execution videos. The man, who is apparently gagged, and may possibly be drugged or injured, is pushed to the ground and his arms are (likely duct) taped to a cross. Once he is taped to the cross, the sound of hammering, and muffled screaming, can be heard as the man moves his legs as if in pain. It is not possible to see anyone actually hammering the nails, but afterwards the video, which is filmed in low light and is very grainy, shows what look like nails sticking out of the man's hands. After this, the cross is raised. The man is clearly standing on a platform (which is not uncommon in crucifixions) but his arms appear to be nailed. At one point, a small fire is lit at the man's feet. Another man jabs him, hard, in the stomach, with what appears to be a torch. After this the man is lit on fire, as his persecutors squirt what is possibly lighter fluid onto the fire, which then climbs up the cross.The video, analyzed below:

Why is the video fake?

When he gets hit with a stick in his stomach it doesn't even look like it's painful. For a man being killed they poke him really nice and kind.

Just before the fire gets too bad, they cut the video.

Yeah right.

Nowhere can the man really be seen getting hurt. His arms are taped, so he can quite comfortably hang by his arms on the cross. It's bad quality video, so details can never be seen clearly. Thus the nails can very easily be faked.

It's as fake as can be.
