У меня есть видео:
Разрешение: 1920*1080
PAR: 65536/65536
Вращение: 90°
В предустановке Fast 1080p30 значением по умолчанию для параметра Anamorphic является « Automatic и «Модули 2 .
Что мне интересно, так это ширина вывода. Высота остается в 1080 как и должно быть. Но как/почему width меняется на 1080 (1080*1080) и выходное видео не растягивается?
Что такое команда ffmpeg или формула для ее расчета?
