you’re kind of stuck. With file based formats, you really need to determine ahead of time what your edit and mastering rate are going to be based on your one or more deliverables and priorities thereof. for example, NTSC broadcast first, protect for a film-out versus NTSC and PAL deliverables, etc.
It also depends on how the files were shot when on the HVX. If shot native at 23.976 you would have had to edit in 23.97. Since the files were most likely shot 23.976 but within a 59.94 file with pulldown you had the choice (before editing):
1. Edit at 59.94 (which you did)
2. Use MXFX tool from DVFilm to extract the 23.976 from the files and edit naively at 23.976.
For productions that cannot go back to redo a native 23.976, the usual path is to take the master output (59.94) with all the cadence breaks and run it through a Teranex or similar device from other vendors (Snell & Wilcox, etc.) to do the conversion back to a native 23.976 submaster.
