The question and title, allow user add!

I would like to host some tutorial videos about electrical work and have them air on TV. I'm an electrician and the videos will be about how to replace switches, outlets or even how to wire a modern kitchen. This may be a tough recording process in some case.
Is there a feasible way to record the whole process that indeed helps the audience?

Appreciating For Kind Answer,Thanks...
When converting either a Blue ray or DVD to my computer, the subsequent mp4 file volume is very low.  When I try to play it on my computer or TV, I have to turn the volume way up for it to be decent output.  I've tried using different audio formats when converting, but it doesn't seem to change anything.
