Removing Right Audio Channel in MKV file

[yuzu28]

Hello, everyone!

I need some help from you guys. I would like to remove the right channel of a MKV file. This video files has 1 audio track, with different language in left and right channel. That's so irritating! Could anyone help me with the command line to remove the right channel? I just need a video file with the left channel and duplicates it to the right channel or mix down to mono is fine.

TIA!

With that type of audio you're supposed to use the stereo balance control (on your TV, amp, player) all the way to the left or right to hear only the language you want.

Could anyone help me with the command line to remove the right channel? I just need a video file with the left channel and duplicates it to the right channel or mix down to mono is fine.

Command line for what program?

ffmpeg -hide_banner -i "in.mkv" -c:v copy -af "pan=mono|FC=FL" "out_monoFL.mkv"

I haven't tested this exact command-line, but I use something similar to downmix fake stereo to mono (lossless).

I am using a HDD to watch the video file. My TV cant select the different language if the source is a USB. Just too bad...

The command line will be for ffmpeg.
