推荐答案

选择过滤器最方便，

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每 33 秒保留前 30 秒.如果您的文件没有音频，请删除 -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.
