Please note that your choice of codec will only apply to *one* output file, the other will use defaults again. Check ffmpeg's syntax description and how to create multiple files. > Following is the illustration of my ffmpeg command. > > ffmpeg -i input -vcodec x264 -acodec libmp3lame output1.mp4 output2.mp3 > > I am thinking of changing it to > > ffmpeg -i input -vcodec x264 -acodec aac output1.mp4 output.mp3 That won't change anything for output*.mp3, because you are not specifying any output options for it. You are a bit unspecific about what you are trying to (exactly) achieve and what is going wrong. Adding the complete, uncut console output would also help.
