Hi - Thanks for the feedback here. I'll fix that commit message. I believe this is the most relevant reference material regarding the userdata ('udta') tag for Quicktime:
https://developer.apple.com/library/content/documentation/QuickTime/Reference/QTRef_AtomsResources/Content/QTRef_AtomsResources4.html#//apple_ref/doc/uid/TP40004285-DontLinkChapterID_1--udta- https://developer.apple.com/library/content/documentation/QuickTime/QTFF/QTFFChap2/qtff2.html#//apple_ref/doc/uid/TP40000939-CH204-63839 From my reading of this, the 'udta' atom can appear as a child of a 'trak' atom, and can have an optional child 'name', which is how this title is being encoded. I've also verified that this is the method by which Quicktime will encode titles if you set them per track using their user interface.
