我在更改视频文件元数据中的时间代码时遇到问题"mov"；
ffmpeg -i input.mov -ss 0 -map 0 -acodec copy -vcodec copy -timecode 01:20:10:00 -metadata:s:2:0 timecode=01:20:10:00 -metadata:s:1:0 timecode=01:20:10:00 -metadata:s:0:2 -metadata:s:0:2 timecode=01:10:10:00 output.mov
我需要把我自己的时间代码放在文件中，但这个命令不起作用。
控制台给我：
mov @ 00000225287fdc00] You requested a copy of the original timecode track so timecode metadata are now ignored
Output #0, mov, to 'convert_A019_02230134_C186.mov':

我不明白为什么它不修改mov文件中的时间代码。旧的时间代码仍然存在。
使用负映射排除原始时间代码数据。
ffmpeg -i input.mov -map 0 -map -0:d -c copy -timecode 01:20:10:00 output.mov
