Re: [Avid-L2] 29.97 to 23.976 for a Series?

I've had issues delivering anything with split frames because the streaming side can't handle it.  Nat Geo for example would not accept 2:3 and wanted 2:2:2:4.  Even though it diminishes the quality of motion that's what they made me do back in 2015.  I doubt they would accept 2:3:3:2 for the same split frame logic.  I had to take 2:3 film clips and motion adapt to single field to progressive for them.  Halving the resolution didn't bother them but split frames did.  Other networks are different and I've only been delivering 23.976 for a long time too.

I hesitate to jump in on this lively discussion, but my experience has been:

1) Since you are “down" converting from a higher frame rate to a lower one, the artifacting in AVID with motion adapters will be minimal. More likely will be the need to watch out for a lack of smoothness in long slow camera moves (frame dropping).

2) The other issue is wether your source footage is 29.97p or interlaced. A large part of the conversion could be de-interlacing. I have been truly stunned at how well Resolve Studio (NOT available in free version of Resolve) deals with de-interlacing 29.97i footage.

3) 23.98 is the de-facto standard in US post community for all the major network shows and tv spots I have worked on for many years. As mentioned previously, nobody broadcasts in 23.98, but it’s very easy to add cadence (2:3:3:2 has become popular, over the old 2:3:2:3 of the “olden days”, apparently it generates fewer interlaced frames in sets that playback frames, not fields). Blu-Ray and DVD manufacturers will routinely master in 23:98 because the compression quality is better with fewer frames, and the DVD/Blu-Ray player add field cadence in th up-convert to 29.97.

4) Nobody is more covetous of their power than a standards engineer or QC checker at a network or streaming company. I have had some of the most idiotic rejections from Amazon that defy logic. Superior technical knowledge has NEVER helped me there.

Good luck John,
