Comments.Text: It seems that you extracted correct video streams (you may omit the `v:` part as the all 3 first streams are video streams). What's your problem?

Comments.Text: When I am extracting the stream, the stream information gets changed for all the streams. For example, `Original` Stream #1 info: `Stream #0:1(eng): Video: rawvideo (b16g / 0x67363162), gray16be.....,` and after extracting the stream, it changes to `Stream #0:1(eng): Video: rawvideo, rgb555le, 640x576,...` I do not want to change anything.

Comments.Text: It would be nice from you to append your comment directly to your question. The stream properties are changed because it will be *transcoded* (i.e. decoded and then encoded with **ffv1** codec, as you specified in  `-c:v ffv1` option). Use `-c:v copy` instead, but without other options for changing the stream's properties.

  I am using this command to extract the first stream:
  
  ```
  ffmpeg -i output_master.mkv -c copy  -map 0:v:0 out_1.mkv
  
  ```
  
  For the other two streams, I am using this command:
  
  ```
  ffmpeg -i output_master.mkv -c:v ffv1 -pix_fmt gray16be -allow_raw_vfw 1 -map 0:v:1 out_2.mkv
  ffmpeg -i output_master.mkv -c:v ffv1 -pix_fmt gray16be -allow_raw_vfw 1 -map 0:v:2 out_3.mkv
  
  ```
  
  I do not know if I am using the right commands to extracting the video streams.
