Hi Jon.
Thanks for your interest. We had decided that showing the before of the 100fps surfer shot played back at 24fps slow-mo would be a bit boring, so we opted for the realtime version. I've just uploaded a slowmo version for you. have a look https://vimeo.com/137804602. Also if you would like to see the real time stabilized skateboard video to compare it with the before, it plays directly after the slowmo version. Skip to 3:48 in that video.
We felt that the best way for you guys to evaluate whether the plugin was any good or not was to make a free demo available. We urge you to try the free demo for yourself before you draw any conclusions. We think you will definitely like it.
