  1. Hi,

    I have a few mp4 videos where (with headphones) the left eared audio needs to be removed, but I want to keep the right eared audio. On mediainfo it says there is one audio stream, but 2 channels. Here is some info:
    Audio
    ID : 2
    Format : AAC
    Format/Info : Advanced Audio Codec
    Format profile : LC
    Codec ID : mp4a-40-2
    Duration : 1 h 24 min
    Bit rate mode : Constant
    Bit rate : 128 kb/s
    Channel(s) : 2 channels
    Channel positions : Front: L R


    Is there a solution to this? Would have thought the fix is relatively simple but searching online I cannot find one. As you may have guessed, I am not a particulary technical person.

    Thanks very much for your help, and if there is more information required please say so.

  2. With one video and stereo audio you could try

    Code:
    ffmpeg -i video.mp4 -c:v copy -filter_complex "[0:a]channelsplit=channel_layout=stereo:channels=FR[right]" -map "[right]" -map 0:0 One_track.mp4

  3. 1. Extract audio and convert to PCM WAV audio: the free AOA AudioExtractor
    2. Remove the one channel followed by turning the remaining one to dual mono followed by saving as AAC audio: the free Audacity
    3. Replace original audio with the new one: the free MP4Box with a GUI

    Hi,
    Please can you explain a bit more. Where would I enter this code?

  5. @Lol

    This is a Command Line Interface (CLI) command.

    You should have ffmpeg in your path or type the path before ffmpeg.

    You open a command prompt and paste in the command.
