                Скрипты для сжатия видео с GoPro и ковертирования RAW в JPG
              
          
    Как сжать GoPro видео с помощью ffmpeg (инструкуция для windows)

Расскажу как круто можно ужимать видео с гопрошки без потери качества.
Видео как правило жмется очень хорошо, мне удавалось сжимать ролики до 70% безо всяких на то проблем.
Для windows-пользователей приложу инструкцию, linux-пользователи и так разберутся, все скрипты приведены ниже.
Установка
