[FFmpeg-user] Remove chapters when cutting a part out of a video

[Cecil Westerhof]

I need to cut a part out of a video. This video contains chapters and
I want to remove this data. I try this with:
    ffmpeg -y                               \
           -ss ${startTime} -to ${endTime}  \
           -i ${inputFile}                  \
           -map_metadata -1                 \
           -fflags +bitexact                \
           -acodec copy -vcodec copy        \
           -avoid_negative_ts 1             \
           ${outputFile}

But this only removes the name of the chapters. They all become
unnamed. And the chapters are not even part of what I cut out of the
video.
What do I need to do to get a video without chapters?
