Я хочу преобразовать кучу видео из x264 в x265, но мне нужно сделать это с помощью ffmpeg в терминале, потому что это удаленный сервер. Это мои варианты ручного тормоза (перечисленные элементы отмечены галочкой):
Вкладка «Сводка»
- Оптимизировано для Интернета
- Выровнять A / V Start
Вкладка «Размеры» без изменений
Вкладка «Фильтры»
- Резкость - LapSharp, предустановка : Средний
Вкладка видео
Код видео c - H.265 (x265)
Частота кадров (FPS) - 30 - Пиковая частота кадров
Качество - Постоянное качество - 28
Предустановка кодировщика - Средняя
Настройка кодировщика - Нет
Профиль кодировщика - Авто
Вкладка «Аудио»
- Аудиодорожка - AA C, битрейт: 128
Вкладка Субтитры - Без субтитров (удалить, если есть )
Это команда ffmpeg, которую мне пока удалось скомпилировать:
ffmpeg -i input.mp4 -c:v libx265 -crf 28 -c:a aac -b:a 128k -max_muxing_queue_size 400 -movflags +faststart output.mp4
У меня есть следующие два квеста ion:
- Предоставляет ли команда ffmpeg список всех параметров, кроме пиковая частота кадров , фильтр повышения резкости и удаление субтитров единицы? Как включить эти три элемента?
- Немного не связаны, но имеет ли
-max_muxing_queue_size 400 отрицательное влияние на размер файла или качество видео? Я включил это только потому, что сталкивался с ошибками кодирования в прошлом.
Спасибо.
Мой журнал Handbrake с указанными выше параметрами, если это помогает:
