Когда я преобразую последовательность EXR в файл QuickTime MOV, используя FFmpeg и кодек x264, он кодирует видео - но в QuickTime Player и Windows Media Player он просто черный!
Но когда я открываю его с помощью VLC, я вижу изображение, и оно выглядит хорошо. Когда я пытаюсь сделать то же самое с последовательностью JPG вместо EXR, она работает отлично! У кого-нибудь есть идея, что это может быть?
Вот мой код FFmpeg:
ffmpeg -y -i C:/seq_v001.%04d.exr -c:v libx264 -preset slow -crf 17 C:/out.mov
Вот вывод консоли:
