Dear Alexey, >From our current (but also mid-term future perspective) referring to the Table >2 in BT.2020-2 (see https://www.itu.int/rec/R-REC-BT.2020-2-201510-I/en ) >would be more than sufficient. Certainly due to associated complexity, for now we may want to limit the frame rates requirement above 60fps to be only supported let's say for up to 1080p resolution, since we're already listing:
| 2160p (4K),3840x2160 | 24, 25, 30, 48, 50, 60 | RA | and the codec levels in the Table 6 already much higher than that? Alternatively, any frame-rate higher than 60fps could be placed into the section 3.2.1 as an optional requirement.

Is my understanding correct that you want to keep fractional frame-rates just for IPTV/OTT/VoD applications? Could you please specify a set of such fractional frame-rates that you would like to include into draft-ietf-netvc-requirements? Thank you in advance! -- Best regards, Alexey Filippov
