Making these work in lego & model building

  • Film the hard step in one clean take, close and well-lit. A single nub-cut or SNOT connection reads as a tutorial, B-roll, and a before-and-after all at once.
  • Put the part number, set name, or grade on screen. Builders stop to check whether they own it, and that specificity signals you actually know the hobby.
  • Shoot top-down on a plain mat with a phone clamp. Your hands and the parts are the whole show, so keep the background from stealing focus.
  • Lead with the finished build or the messiest before-shot, then rewind. Nobody watches a twenty-minute build blind, so promise the payoff in the first frame.
