Answer 1

重置 PTS，然后使用 drawtext 过滤器和 concat。

ffmpeg -i Vidos1.mkv -i Vidos2.mkv -i Vidos3.mkv -filter_complex \
   "[0:v]setpts=PTS-STARTPTS,drawtext=text='Good ':x=0:y=h-th:fontsize=24:fontcolor=white[0v];\
    [1:v]setpts=PTS-STARTPTS,drawtext=text='God ':x=0:y=h-th:fontsize=24:fontcolor=white[1v];\
    [2:v]setpts=PTS-STARTPTS,drawtext=text='Go ':x=0:y=h-th:fontsize=24:fontcolor=white[2v];\
    [0:a]asetpts=PTS-STARTPTS[0a];[1:a]asetpts=PTS-STARTPTS[1a];[2:a]asetpts=PTS-STARTPTS[2a];\
    [0v][0a][1v][1a][2v][2a]concat=n=3:v=1:a=1" ...
