I agree with , these really long videos (as I did myself for my minimap) are not really ideal to attract a potential customer who was not specifically searching for a blueprint solution. I will create a second video which is 60-90 seconds long to quickly show what’s possible, so only explaining the what, and not the how 
But I think the short video should be visible directly in the marketplace without clicking on a youtube link. More like the screenshots, so that people simply click a button and can watch a short video without going to youtube 
When there is not integrated solution for this, the description is like "Short Video: <Youtube Link>, Long Video: <Youtube Link>, and I think if someone only wants to look through what’s on the marketplace this “clicking on a link which opens youtube” is a barrier.
