Re: [Avid-L2] 29.97 and HD / RANT

Well, of course that's absolutely true. For me, I've never concerned myself with whether or not a BD I had was 24 or 23.976. Modern players and displays handle the variations with ease and aplomb!

As well, I only ever escort a show up through DPX files for use in making the DCP. Whatever masters they derived for home video and other markets haven't been an overriding concern of late, not with playback and display technology being what it is today. Needless to say, I'm sure there is still specific work being done to accommodate 24fps originators  when prepping for broadcast in PAL-land.

But the issue at hand was whether or not BD's were mastered at 23.976 or 24.000. I have seen both, and to the best of my knowledge there is no reason to prefer one over the other. Most of the films I worked on had European BD releases at 24.000 while the US BD was 23.976. Most likely that is because they can use the same 23.976 master file to encode for BD and DVD.

I don't know about statistically true, but anecdotally from personal experience, with the many features I've done, including all of the foreign language movies, including all of the Eastern European/Russian-language films, most all of which were mixed here in L.A., the sound post people always deliver two distinct sets of audio deliverables — 24fps and 23.976 fps (and of course in 5.1, in LtRt, etc., etc., plus M&E's, etc.).

All of these movies were shot at 24fps, including the Russian-language films, as that's how they're exhibited in Russian cinemas, in spite of their 25fps PAL TV standards.

I have no idea if this is statistically true, but my BD collection has tons of titles, both at 24.000 and at 23.976. Typically, if a movie is shot and posted at 23.976, the video master used for the BD release will be 23.976. If the movie is shot and posted at 24.000, the video master will be 24.000, and the BD release will be 24.000. The latter has been the case for 90% of the stuff I worked on for the past decade.

Bottom line: they are two different playback rates, and therefore require different audio deliverables to match.
