How to change the container of video file using FFmpeg -c copy command.

If you want to change the container of a video file (no transcoding), you can use FFmpeg and the -c copy command.

Keep in mind I keep FFmpeg exes in a folder called PATH_Programs, so I put the video file in the same folder.

Let's say you want to change video01.mkv to video01.webm. I would open the Command Prompt (with Administrator Rights) and type the following:

C:\PATH_Programs>ffmpeg -i video01.mkv -c copy video01.webm

FFmpeg will just change the container from Mkv to Webm.
