Using ffmpeg to copy metadata from one file to another
Use -map_metadata
.
In this example the global and stream metadata will be copied from in0.mkv
. The video and audio streams will be stream copied from in1.mkv
:
ffmpeg -i in0.mkv -i in1.mkv -map 1 -c copy \
# copies all global metadata from in0.mkv to out.mkv
-map_metadata 0 \
# copies video stream metadata from in0.mkv to out.mkv
-map_metadata:s:v 0:s:v \
# copies audio stream metadata from in0.mkv to out.mkv
-map_metadata:s:a 0:s:a \
out.mkv
This will result in something like:
Output #0, matroska, to 'out.mkv':
Metadata:
title : Global Title
AUTHOR : Global Author
Stream #0:0: Video: h264
Metadata:
title : Stream 0 Title
Stream #0:1: Audio: vorbis
Metadata:
title : Stream 1 Title
By default global metadata is copied from the first input file, so -map_metadata 0
could probably be omitted.
