I would like to place the audio from a video to another video without an audio (in one command): ffmpeg.exe -i video1_noAudio.mov -i video2_wAudio.mov -vcodec copy -acodec copy video1_audioFromVideo2.mov I guess "-map" is the correct way to do it but I got confused with it. Can you suggest how to resolve it?
