Hey there. I don't think it's about whether you should delete the video or not (well I mean in this case, it isn't as if your performance really is giving everything away), but more about your performance itself.
Since you have a video camera, and you know how the trick is supposed to look like, I'm sure you can just keep on making recordings until you make one that is good. This is in reference to other posts which mention some awkward hand gestures. Doing multiple recordings, going back to the ones you did and see where you went wrong or could have done better, and doing it again and again till you get a decent looking version would erase all the problems you face in this video.
Because frankly I don't think the fault lies in you not being familiar with the technique, or lacking confidence; I think it has something more to do with practice maybe, I don't know. Anyway I think it takes a lot of guts to actually record your performances and sharing with everyone, so it's not all that bad. Just practice more, and focus on the
whole performance instead of just whether or not you got from point A to point B.
PS. If soda is expensive, then well... Erm keeping practicing till you eliminate all awkwardness in movements before you make a recording.
PPS. Oh and, watch out too for where your eyes look. They tend to signal the audience where to look, so if you are fumbling with something in your hand and you instinctively cast your eyes at them, people will take the cue and also look at your hands, which would just make things worse.
The best thing about having a camera is you can learn from all your recordings! An advantage I don't have...
