I've been thinking about that vid quite a lot.
First, as snafu says, it's a pretty basic choke from the guard that any blue belt should know - the detail with the t-shirt is what makes it interesting. (Renner and his bro have a whole DVD of t-shirt chokes you can buy, I think - they also use a little bracelet tool you can carry in your hand to create a million more choke variations without the gi - I remember watching a trailer for the did years ago, something like 'choke people from anywhere! (Tm)')
Second - there's a huge difference between 'yeah, I saw this in a dvd once years ago' and having the ability to actually make that work on a resisting opponent. So, I don't know how 'honest' it is to show that on a video and expect people to make it work without months of practice. What makes BJJ effective is a combination of 2 things - the techniques and the constant, repetitive practice of trying to apply them against highly resistive people actively trying to stop you. It's not going to work for you after watching that video - chokes require a huge amount of sensitivity and feel to get right, kind of like riding a bike. The right amount of pressure in the right place, the slight angular ion of a wrist or hand, it's all the kind of stuff that's picked up through months of practice on people.
If you haven't got that under your belt then I'd let anybody do that t shirt choke on me, and I bet I could nullifying it just by holding my neck stiff and at the right angle. I'm sure everybody over blue belt in BJJ has had beginners collar choke them with both hands in the collar and just sat there and smiled because there's no threat. It's not easy! Then you have to factor in them using both their (free) hands to defend the choke (not shown in the video) because that's what they'd do in real life - why is the 'rapist' in that video not punching her in the face, for example?
I guess the point of the video is to try and get people into their courses to try out some of these things, so it works in that sense as a marketing tool. I'm conflicted about the rest of it - yes, it's probably the most effective thing to do in that situation, but equally, they're making it look too easy in the video.
