Yes, smpte S268 refers to field 66 as "Temporal sampling rate or frame rate (Hz)".

I find AJA cards generally seem to "do their own thing" when it comes to metadata, some of their .mov fields are way different to everyone else's (like not setting the aspect ratio on HD ingests) > > Best Regards > Christoph > [...] -- Tim.
