The clip comes from advertising material for TIM Ultrafibra, the Brazilian fibre internet service from TIM, where speed is the central selling point and velocidade is the Portuguese word for it. Its credit to Roastbrief points to an advertising origin rather than a film, series or game. Cut down to a couple of seconds, the word began circulating on soundboards as a standalone reaction, separate from the full advert. Its appeal is simplicity: one familiar word instantly signals fast internet, fast movement, or a fast result without needing any context.
