I am opening another issue that could probably be a discussion, but you will have to activate the discussion functionality for the repository on GitHub. Or point me to the best place to have such discussions.

Recent versions of EasyDCP have now a setting to change the validation method used to validate the DCP, there are three methods: Fraunhofer, SMPTE ST 429-2, SMPTE RDD52. I was wondering to which method/profile does the default ClairMeta configuration is the closest too?

@robin-francois Unfortunately I cannot activate discussion for now so let's discuss here.

Thanks for the note, I was not aware of this update, I think the equivalent in ClairMeta would be the check profile JSON file, which allows control over what checks are executed and their error level. The defaults are in https://github.com/Ymagis/ClairMeta/blob/develop/clairmeta/profile.py#L12.

I'm not sure where we stand exactly and what the "Fraunhofer" profile does differently. SMPTE RDD52 should be a superset of constraints over SMPTE ST 429-2 if I remember correctly and ClairMeta should be somewhere in between. We started adding some RDD52 related tests and already had implemented others before the document was published but don't support everything in that document.
