I had the same thought, but why would ffmpeg, when remuxing, re-insert the original id3v1 tags? Perhaps they're considered part of the stream, *then* they would survive "-c:a copy". You may want to try adding "-write_id3v1 1", as hinted in the docs: https://www.ffmpeg.org/ffmpeg-formats.html#mp3 In both cases, that should either drop the metadata or insert both versions. (I didn't manage to test, because I don't have any tools at hand which expose both/all types of tags in MP3 files. exiftool should manage.) Other suggestion (never confirmed): https://lists.ffmpeg.org/pipermail/ffmpeg-user/2011-June/001365.html Actually, there are so many forms of tags (incl. EXIF), metadata, and so on, that other tools may be much more suitable for such operations. Cheers, Moritz P.S.: I found "-map_metadata -1" on lists and superuser.com, but neither in the docs nor the wiki.
