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

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,
