Expanding Deck Sub-structure

What happens here

In a quick sequence, the deck's sub-structure visibly expands, with numerous joists laid out in parallel. This indicates the framing for a substantial portion of the deck is being assembled efficiently. The joists are secured to perimeter beams and potentially to ledger boards attached to the house.

Goal: The video shows the rapid progression of the deck framing, with more joists being added, suggesting a time-lapse effect, and demonstrating the expansion of the deck's footprint.
