Firstly,this is very uncomfortable to watch or listen to. If you access it via a phone with headphones you can listen without watching it. It is very explicit in places but the gist is clear from the audio only.
Jade says at the beginning "porn is nice" and the men involved "respect" her unlike men in real life.
Unfortunately "nice " means having unprotected sex ; ending a shoot frequently in tears, and, in one case, sex which leaves her bruised and bleeding. It is also painfully clear the male actor in a shoot in Prague does not "respect" her in the slightest.
For a 14 hour shoot in Prague she got £500 or around £35 per hour. Factoring in the travelling time to and from Prague reduces that to £10 per hour.
The film maker asks her at one point if she's never thought of getting an office job to which she replies something along the lines of "and lose my soul?" As it is, being a porn star seems to consume her life; it seems incompatible with sustaining any non-porn relationships.
Oh and as for "ethical porn" it would be impossible to argue Jade is not consenting to this; at least one of the shoots was directed by a woman but I'm struggling to see anything ethical in it.
I attach a link, but as I say you may prefer to listen to it rather than watch.
