I have a video AVI file, "Video.avi", consisting of a video and an audio track, and a separate audio file, "Audio.mp3". I want to do the following two things:
(1) First, I want to produce a version of the video, "OutputSilenced.avi", which would be identical to the original video except that the first 90 seconds of the video's audio are replaced with silence (to clarify, I want to REPLACE, as in overwrite, the first 90 seconds, NOT insert 90 seconds of silence to push the audio back 90 seconds). (2) Second, I want to produce a version of the video, "OutputReplaced.avi", which would be identical to the original video except that the first 90 seconds of the video's audio are replaced with the first 90 seconds of "Audio.mp3" (again, to be clear, I want to REPLACE, as in overwrite, the first 90 seconds, NOT insert 90 seconds of audio to push the original audio back 90 seconds). How commands would I use to do this with FFmpeg? Ideally, I would like to just remux without doing any re-encoding. Thanks in advance. _______________________________________________ ffmpeg-user mailing list [email protected] http://ffmpeg.org/mailman/listinfo/ffmpeg-user
