· One min read

Setting up#

First make sure you have FFmpeg installed. Follow this guide if you haven't already:

Running the CLI#

You can use the map command to remove streams from media files with FFmpeg. The stream index begins at 0, so, for example, to remove the first stream in the file you would use -map -0:0, to remove the second stream you'd use -map -0:1:

ffmpeg -i "C:\Transcode\input.mkv" -map 0 -map -0:1 -c copy "C:\Transcode\output.mkv"

You can also remove streams by type. For example, to remove the second video stream you'd use -map -0:v:1, to remove the second audio stream you'd use -map -0:a:1 and to remove the second subtitle stream you'd use -map -0:s:1. You can use these commands together to do them all at once:

ffmpeg -i "C:\Transcode\input.mkv" -map 0 -map -0:v:1 -map -0:a:1 -map -0:s:1 -c copy "C:\Transcode\output.mkv"

You can automate this process on your files using the following Tdarr Plugins:
