22Mp : quand le choix de la résolution d'un capteur photo dépend de critères... vidéo.

" I have no insider information, but just wanted to point that 22 MP has some “magical” properties for HD video, as it corresponds exactly to a 3×3 oversampling of the final video resolution. (22 MP, minus crop for 16:9 ratio, divided by 9, equal 1080×1920)

The next “magical” resolution (4×4 oversamping) is at 39 MP. "
