Replacing the audio track or simply deleting it can be done with any program that is capable of editing video. For example, if several audio tracks are embedded in a video file, while significantly increasing its size, you can easily "throw out" unnecessary ones with just a few operations.
Necessary
Video editing software Virtual Dub, MKV Toolnix or TSMuxer
Instructions
Step 1
The simplest video editing program that can handle a lot of operations is Virtual Dub or Virtual Dub Mod. It is a free, small but functional program with its own set of codecs.
First, through it you need to open the required file (menu "File" - "Open"). Then you need to go to the "Streams" item (also in the top menu), and select "Stream List" (the item responsible for editing streams). Then, with the left mouse button, those audio tracks that need to be deleted are selected, and the "Disable" button is pressed. Inactive audio streams are highlighted in gray, and now you can press the "Ok" button.
Step 2
Then you need to go to the tab "Audio" - "Direct Stream Copy", and "Video" - "Direct Stream Copy", after which you can save the file ("File" - "Save Video"). Tracks are deleted.
Step 3
If the video file is in mkv format, then Virtual Dub will not always be able to cope with it. Then the MKV Toolnix package comes to the rescue, which includes the mkvmerge GUI program. It perfectly and quickly copes with deleting unnecessary tracks from the selected file.
After downloading the file ("File" - "Open") the program displays a list of all video parameters. Then you can simply uncheck unnecessary items. After selecting the directory to save the target file, press the "Start" button.
