You definitely need to randomly decide the order of the videos if you want this at all to be a "fair" poll. Most people are going to pick the first one they watch because since they already know what the content is going to be, and already have the image of the product "branded" in their mind, the second video will be both boring and dissonant [1]. They won't be able to wait for it to just get to the point, and they won't be as comfortable with the different image of it. For even better accuracy, you could try showing people only 1 video, and having them rate it from 1-10 on a just a few questions, then compare the results.
My personal preference was for #2, which I happened to watch first. I liked the music, and every frame got me more and more interested in the next. The theme of "the world has you up against a wall... no here's the solution" resonated very well with me, and I think it's just the right approach to take with writers. It was entertaining, the music was catchy, and after it thoroughly explained the problem, it showed the glorious solution of test99. The flow of it was really awesome, it was well-scripted, cute, funny, just great. Really, I actually enjoyed it. It explains the problem brilliantly, even if you're not familiar with the domain of publishing, and explains how test99 is a great solutions. The attitude is generally pretty "kick-ass". I think it would work well with VCs.
The second video I watched (video #1), I found to be boring, and extremely trite. It seemed like a poorly done and unimpressive Apple commercial. I just couldn't stomach it after awhile. I quit a few seconds after seeing "step 1 -- start an account" and the user going really, really slow. I understood where it was going from there: "Here's how you use this, step by step, you fool! We'll go extra slow so you can follow." I could see the appeal of this video for people who want to be feel "comforted" with a product and have a slow attention span, as opposed to people who have drive and ambition and want to break ranks quickly and fairly (that is completely video #2). Which would you classify aspiring writers as?
Video #1 isn't as terrible as I make it out to be. Both videos get the product pitch across quite nicely. But, I'd have to go with #2, all the way. It explains the problem (possibly for too long), makes me believe the problem is really a huge problem that is unfair and that needs to be corrected, then shows your product at the climax, and gives a brief enough description of it for me to want to try immediately.
Either way, I strongly suggest doing this in a more controlled manner if you plan to make a decision from the polls. And, great work so far. This product seems awesome, and I'm quite excited for you.
