I have filmed quite a number of my punts and although it costs extra (usually), I would say that watching some of the videos of the better punts can be a good alternative to a further meet. I have limited time to punt so this works out well for me, although this wasn't the reason I started filming.
I also found that it's worth asking girls if they will allow filming even if it's not listed on the profile, the offer of a bit of extra cash often works and the fact that I do not share these clips, and I ask the girl if she wants to wear a mask (if they prefer) seems to give them a bit of comfort in terms of privacy.
