It seems to me that to have people make videos and then discard a lot of them without ever looking at them (which the text suggests is the case) would be a lot of wasted effort ?
We're doing a little 1-2 minute video explaining our stuff at the moment and staying rather lo-fi and plan at least 10 hours of work on it.
Trying too hard to pitch in the video is actually a mistake, because it makes the video stilted.
Sounds like a good risk/reward profile for my effort to me.
In the end I shot my video with a cell phone camera. Took two takes and about 5 minutes. Finding the right location for it took a little longer, but fortunately the place just popped up one day while walking around town.
