Uma gravação. Dois arquivos. O Dual Frame grava o enquadramento vertical 9:16 e o horizontal 16:9 ao mesmo tempo, e entrega dois arquivos independentes e sincronizados. Não é um corte feito depois: os dois nascem da mesma tomada, do mesmo áudio e da mesma linha do tempo. DUAS LENTES DE VERDADE No modo de duas lentes, a câmera principal grava o vertical e a ultra wide grava o horizontal — dois ângulos reais, ao mesmo tempo. A coluna ao lado do preview vertical troca a lente dele, de 1× a 8×, sem mexer no horizontal. UMA LENTE, ÁREA MÁXIMA DE SENSOR No modo de lente única, o app ativa o formato de maior área útil que a câmera oferece e recorta na GPU, em tempo real. Partindo do 4:3 de sensor cheio, o vertical sai bem maior do que sairia de um 4K 16:9 convencional. O APP NÃO ESCONDE NÚMERO Cada formato mostra a resolução real que vai para cada arquivo, o ângulo de visão, a taxa de quadros e se ele estabiliza. Nada de alta, média e baixa. Se uma resolução não está na lista, é porque o seu iPhone não a oferece. TAMBÉM TEM • Foto durante a gravação, no mesmo enquadramento, sem interromper os arquivos • Apple Log quando o formato oferece, com conversor para Rec.709 embutido • Escolha de estabilização, sabendo quanto cada modo recorta • HEVC ou H.264, MOV ou MP4 • Toque para focar e expor, arraste para ajustar o brilho • Galeria com filtro por formato • Salvar na biblioteca de Fotos, na pasta do app, ou nos dois PRIVACIDADE O app não coleta nada. Não tem servidor, não faz conexão de rede, não usa análise nem publicidade. Tudo o que ele produz fica no seu iPhone. REQUISITOS iOS 17.2 ou mais recente. O modo de duas lentes exige um iPhone com suporte a MultiCam; em aparelhos sem esse suporte, o app funciona em lente única.
