A discrete cosine transform (DCT) has the property of revealing the original resolution of images that have been scaled.
All captures were taken on PS5 and PS3. The algorithm for detecting resolutions is not yet 100% reliable, so consider the closest observed value in the DCT image.

The link to the article explaining the method is in my video comment below.

A transformada do cosseno discreta (DCT) tem a propriedade de revelar a resolução original de imagens que sofreram escalonamento.
Todas as capturas foram realizadas no PS5 e PS3. O algoritmo para detectar as resoluções ainda não está 100% confiável, então considere o valor mais aproximado observado na imagem DCT.
