Улучшение скорости транскодирования в aws mediaconvert

Question

Я использую AWS Mediaconvert для добавления водяных знаков и создания миниатюр из видео. Процесс транскодирования занимает около 7 секунд. Вот мой файл JSON

Входное видео - файл размером 480x848 с размером 3,35 МБ и общей скоростью передачи 1600 Кбит / с. Я хотел бы улучшить скорость транскодирования. Где можно настроить вышеуказанный JSON-конфиг для достижения лучшей скорости с минимальной потерей качества
