After having bought and watched the clip, the sad truth has to be said:
This is a somewhat dishonest way for the maker of the film to make money. I say this because:
1. Even with existing know-how and technology, the clip could and should have been longer.
2. As with my previous point - more such clips could have been made already, and for this price, they should have been bundled in one file or zip file.
3. This site serves people who are, how to put it moderately, admirers of the aesthetics of both braces of all kinds, and their wearers. So, posting such a clip here, when only 5 seconds of it are actually showing anything, is teasing, if not worse than that.
4. As was well said before me, it is very easy to produce still images of the the wearer and her brace, and the fact it had not been done so far, despite the positive feedback and general appraisal from this community, says "not-so-positive" things about the producer, who I thought was one of us, or at least has the minimum understanding about this forum (does not have to be a genius, mind you).
5. If I knew all this when I paid for the movie and exposed my personal data to the mercy of an anonymous party, I would have not done it.
I challenge the maker of this film - Either make more media available, or refund me for the sheer disappointment.
I know I speak for many, albeit my style is a bit harsh.
