Я в течение минуты записывал видео на мобильный Android, чтобы обнаружить, что к тому времени, когда я прекратил запись, телефон был выключен. Почему он выключился, я понятия не имею, потому что батарея была "синей", а не "оранжевым" уровнем. Во всяком случае, VLC отказывается воспроизводить файл. Инструменты для восстановления видео довольно дороги, и самый известный инструмент Video Repair показывает только предварительный просмотр в течение нескольких секунд, который, как утверждается, составляет 50% от всей длины восстановленного видео. Таким образом, я пришел к выводу, что он может восстановить только около 10 секунд минутного видео.
Вот журнал VLC на уровне многословия 2:
