I just successfully encoded a DCP from a ProRes file with a frame rate of 29.97. I ran it through the Player's verification process, and it returned the following error under the SMPTE Bv2.1 tab:
The video asset ***.mxf uses the invalid frame rate 30/1.
Isn't that bit misleading? I know 30fps used to present a greater possibility of playback issues on some projection systems, but is that still the case in 2023?
Conversion to 23.976/24fps for this project won't be an option.
Why does Player report an "invalid frame rate" error for 30fps?

The SMPTE Bv2.1 standard (that these warnings are taken from) only allows 24, 25 and 48fps (for 2K) and 24fps (for 4K). I don't know what the real-world likelihood of 30fps working is these days.

Thanks Carl. Is this version dated May 18, 2020 the most recent:

Yes. There haven't been many revisions of that document. 30fps will work on most systems (but not all). The verification in DCP-o-matic player, though, has to complain about this.
