Я пытаюсь вырезать видео 4K @ 60fps, используя FFMpeg 3.2.4 (x64) для Windows без перекодирования:
ffmpeg -i D:/video/qc_01.mp4 -c copy -ss 00:27:00 -to 00:56:00 D:/video/01.mp4
Я получаю почти пустой файл (290 байт), и он выводит это:
D:\video>ffmpeg -i D:/video/qc_01.mp4 -c copy -ss 00:27:00 -to 00:56:00 D:/video/01.mp4 > output.txt
