I was quite disappointed with Lumen5, but perhaps I did something wrong. It seemed to just pick a few sentences from my article at random. Since this was a philosophy text, you can't just pick sentences 5, 7 and 23 out of it, hoping that the result makes sense. It didn't. Also, the resulting video was always under 2 minutes and I didn't see how I could make it longer. Do you have an example of your own of a convincing Lumen5 video?
