If you want to do a technical video, I would recommend that you emulate the format of things such as MinutePhysics or CGPGrey.
Its basically a technical video with pictures and some humor, and it is presented to you at 100 miles an hour, talking quickly and moving on to the next idea quickly.
This might seem absurd, because it is presented to the viewer WAY too fast for them to actually understand or internalize anything! But it makes the video exciting and fun, rather than boring. The result is that someone who is less interested will be able to actually watch the video through once, instead of turning it off, while someone who is very interested will just watch it over and over until they feel they understand things.
I wish we had bitshares related videos like this.
