When the OP mentioned "video" tutorials, I assume "animation with sound."  Not having done any, and not having checked to see what animation or sound tutorials already exist, maybe something (in stages would be fine) about animation, phonemes, sound, and lighting to make a Poser music video starring w/e character the user wants - NearMe singing country, for example.

Animate the figure + phonenes + moving background (like a painting on a roller that scrolls by in the background independent of what the singer is doing) + how to sync up the sound.  Wind effects, lighting, rain / mist, w/e as the background changes.
