AF
ну так -vcodec copy убери
AA
а scale зачем?
AF
иначе он не может скалировать
AF
картинку уменьшить
AA
зачем?
AF
понизить время отработки создания файла
AF
ну и конечный файл будет меньше в два-три раза
AA
мля. при "-vcodec copy" будет минимальное время. Размер файла очень важен?

при кодировании h264 проц грузится на 100% - это бОльшее зло чем размер файла, если макс. скорость записи носителя во много раз больше скорости видеопотока

хотя да, есть
