I know this is kind of late but I have been having the same problem with individual clips, not an XML. I import a .cine file with 24fps, and I want to export 23.976 (don’t ask me, it’s the editor’s required frame rate). Everything in Davinci is set to 23.976 until it is exported, but the resulting .mov is 24fps when opened in quicktime, or any editing software.
Thanks,
Jackson
