kodujący czytelny film przez QuickTime przy użyciu FFMPEG

Question

Próbuję kodowania sekwencji obrazów za pomocą następującego polecenia:

ffmpeg.exe -i %d.png -f mp4 -vcodec h264 test.mp4 

Jednak QuickTime nie udało się otworzyć ten plik lub czasami zagrać czarny film, podczas tego filmu gra świetnie w odtwarzaczu VLC. Wszelkie sugestie, jak sprawić, by grała dobrze w QuickTime?

Oto wynik:

ffmpeg.exe -i %d.png -f mp4 -vcodec libx264 13.mp4
