Not for sure, but... if they were being dragged like that, they couldn't be conscious anymore.

Did you know? It takes a lot of trauma to knock someone unconscious. Movies always make it seem easy, but if someone gets knocked out, the damage is usually pretty severe. It's rare for someone to fall unconscious for very long without sustaining any brain damage.

Other than that... if they passed out from pain or bloodloss, I don't think it's likely that they would have survived unless someone treated them. So whether or not they were alive during the video...

I-I don't think they could still be alive now.
