If using something else like mkv or mp4, they do not appear. In both cases (output to .thd audio only file or mkv/mp4 container) the Atmos is stripped. I guess this is normal when outputting to .thd ? -- Ticket URL: <https://trac.ffmpeg.org/ticket/11307#comment:3> FFmpeg <https://ffmpeg.org> FFmpeg issue tracker

If the user has set a timestamp precision, then that should be honoured; **but if not, then we might use a different value than 1/1000** (in the future; I know that currently no code path that makes use of this exists). I doubt this will be implemented. -- Ticket URL: <https://trac.ffmpeg.org/ticket/11307#comment:7> FFmpeg <https://ffmpeg.org> FFmpeg issue tracker

It only occurs when output to .thd audio. I never have a use for this since my outputs are in mkv where it does not occur. I accidentally came across this when I was testing something else. -- Ticket URL: <https://trac.ffmpeg.org/ticket/11307#comment:9> FFmpeg <https://ffmpeg.org> FFmpeg issue tracker
