Portal dimensional se abrindo em praça vazia

A shimmering dimensional portal tears open in the middle of an empty concrete plaza, camera holds a static wide shot as swirling energy ripples outward in concentric rings of blue and violet light, debris and loose papers are pulled toward the vortex, electric arcs crackle along the portal's unstable edges, 7 seconds building to a bright flash as the portal stabilizes into a clear window to another world, deep bass rumble with high-frequency electric crackle sound design.

Sugestão: peça 'stable portal geometry, no chaotic random shapes' para manter a abertura com uma forma consistente entre diferentes tomadas da mesma cena.
