Video presentation needs to be clear, and done in a professional manner. A good videographer and a great editor will make a huge difference on your product. If you have the skills to build a very good
cob oven, and you have someone who can film it well, and someone who can edit the film so that it is concise and clear, then you might have a product people want to purchase. Look at youtube and watch a few videos on any one subject. You will find people often waste a huge amount of time talking or filming things that are not on topic, while the details of what the video is supposed to be about are slim. When it comes down to it, the video's actual beneficial content is only two minutes but you sit through 13 minutes to get that morsel. Another thing to do is to make it fun, and people will be drawn to it infectiously, and if you are going to do a series then create your own style, and maybe have your own quirky bit that people will recognize without overwhelming everybody with this trademark.
