+== Example 4 ==
+
+If we want to re-encode just the video streams, but copy all the other streams (like audio, subtitles, attachments, etc), we might use something like this:
+{{{
+ffmpeg -i input.mkv -map 0 -c copy -c:v mpeg2video output.mkv
+}}}
+It will tell ffmpeg to:
+- read the input file 'input.mkv'
+- select all the input streams (first input = 0) to be processed (using "-map 0")
+- mark all the streams to be just copied to the output (using "-c copy")
+- mark just the video streams to be re-encoded (using "-c:v mpeg2video")
+- write the output file 'output.mkv'
