I'm trying to replace just a segment of audio in an existing video with another piece of audio.
Goal: I have a video w/ audio, and want to replace just the audio in a middle segment of the video without affecting the rest of the video and audio. The closest I've come is using this: ----- ffmpeg.exe -y -i "Video.mp4" -i "AudioToReplace.mp3" -filter_complex "[0:a]atrim=0:316,asetpts=PTS-STARTPTS[aud1];[1:a]atrim=0:172,asetpts=PTS-ST ARTPTS[aud2]" -map 0:v -map "[aout]" -c:v copy -c:a libmp3lame New.mp4 ----- It results in the audio being replaced in the beginning of the video and the rest of the audio shifted. I'm having a difficult time understanding what the 'filter_complex' and 'map' parameters are doing but I think I'm getting close. Can someone please explain these and help me adjust my command above in order to achieve my goal?
