У меня есть сотни видеофайлов в формате m2ts, полученных в результате легальных записей с телевидения. Теперь я хотел бы сохранить их, но они огромны.
Есть ли какой-нибудь формат, в который я могу их преобразовать, и в который желательно без потерь? Контейнер MKV был бы хорош, но не обязателен, как и читаемость на iPad.
Linux или Mac решения в порядке.
