Agreed, if you can't make more videos - hire someone to help you. Or help promote a smaller channel through advertising.
By the ways video guides are good idea. I hope that all the most important questions can be filmed. So there will be less questions
It's not a bad idea, that can attract attention is when a team attempts to communicate directly or indirectly with the community, so that they get the answers of their questions. In addition the video also gives more value than any project that doesn't include any video in their projects.
