Negative map is very powerful!ДЄctually, in the previous section, we learned how to remove audio from your video using -an, right? You can do this using negative mapping as well as follows. By saying -map -0:a:0 you are telling FFmpeg to ignore the first audio track. If you have 5 audio tracks and you want to select all but the first one, then you can use the negative map command. ffmpeg.exe -i videoWithAudio.mp4 -map 0 -map 0:a:1 -copy videoOutput.mp4 So, basically, you are selecting everything and then de-selecting the audio. In our example, if your file has 1 video track and two audio tracks, then you can use -map 0:a:1 to only select the second audio track and copy it to your final output.ДЄlso, -map 0 selects everything from the first input.

So, you could select the 2nd audio track of the video by saying -map 0:a:1 because the numbering starts at 0. The general syntax of the map command is -map input_file_index:stream_type_specifier:stream_index.
