Legality of mixed Interop and SMPTE assets #227

Open overlookmotel opened 1 year ago

overlookmotel commented 1 year ago

We recently received a DCP to be presented at a film festival which is Interop standard (Assetmap etc use Interop XML schema) and has the audio MXF in Interop format, but the video MXF is SMPTE.

ClairMeta does flag this:

CPL assets labels / schema coherence check.
MXF Label incoherent, got SMPTE but expected MXFInterop

However, by default this is flagged as a warning, not an error, which surprised me. Am I wrong in thinking this might well not play back reliably on all projectors?

Does anyone have an opinion on this?

This strikes me as being a messy, unpredictable dcp!

Unfortunately I don't remember the rational for it being a warning, I assume it was from feedback in the field. If anyone has experience with such an issue producing an error on playback, we can surely raise it as an error.
