I went that route to be most compatible with foobar2000, which is using a similar approach (at least at the time). It's basically a representation of the chapters in Nero form — your original chapters are still there. > [@markf](#): > > Is there any way to suppress the addition of the Nero tags? No, it's currently not possible. > [@MotleyG](#): > > By "Apple gapless data" are you referencing the legacy ITUNESGAPLESS pgap field that needs to be set to 1? This was a different issue that has been fixed with v2.93a. Back then, Mp3tag created the `chpl` atom in that case no matter if chapters were present or not. > [2019-01-29] CHG: chpl atom was created if Apple gapless data was present. ([#44323](https://community.mp3tag.de/t/44323)) > [@MotleyG](#): > > In the case of the OP's concern, is the indication of "MP4 NERO" just a change of format based on how mp3tag handles chapters in m4a? I don't think there are other specific tags added, just the format change, correct? It's an addition of the Nero representation. No change of the existing format. --- _[View the full topic](https://community.mp3tag.de/t/nero-tag-created-when-making-minimal-change-to-m4a-file-with-chapters/56259)._
