推荐答案

选择过滤器对此最为方便，

The select filter is the most convenient for this,

ffmpeg -i in -vf "select='lt(mod(t,33),30)',setpts=N/FRAME_RATE/TB" -af "aselect='lt(mod(t,33),30)',asetpts=N/SR/TB" out

视频和音频选择过滤器使前33秒保持为每33秒一次.如果您的文件没有音频，请放下-af ..选项.

The video and audio select filters keep the first 30 seconds out of every 33 seconds. If your file doesn't have audio, drop the -af .. option.
