FFmpeg video metadata change

Question

I am trying to change the video stream metadata. See (Change This Metadata) below. I can change the title of the movie ok but not any others. What is the ffmpeg line to change this.

This line below changes "Title Of The Movie" only

ffmpeg -i Input.mkv -metadata title="New Title" -c:v copy -c:a copy -c:s copy Output.mkv

Input #0, matroska,webm, from 'Input.mkv':

Answer 1

Ok I have found this which works:

ffmpeg -i Input.mkv -metadata:s:v:0 title="H264 Video" -c:v copy -c:a copy -c:s copy Output.mkv

I think :s:v:0 some of the comments stands for:

:v = Video stream :0 = Use first video stream
