Conversion from 24.000 to 23.976
I've just recently seen a BTS video of the production for Dune (2021) with the cameras shooting at 24.000 frames. The Web version (HBO Max) that is now available shows up on my receiver as 23.976.
It seems (after a bit of googling) that this is quite common and indeed most of my Blu-rays are also in 23.976. As far as I can see the DCPs are kept at 24.000 and then the conversion is made for Streaming/Home releases, is that correct? If so, where is the conversion made and how? Is the film just played back 0.1% slower (resulting in it being slightly longer)? And is the audio time stretched by 0.1% and then kept at 48kHz or do we get a weird kHz number as well? Does the pitching usually happen after the final mix and is just made from the stems with Serato PnT or similar? And regarding current big productions: How is this done in Atmos? Can the Dolby conversion tool do that or is there rerendering going on? (Maybe from the cinematic mix in the RMU to the 7.1.4 or similar HT version/renderer?) Any (also partial) inputs are appreciated, thanks :) |

Personally I don't bother with pitch change with 23.976 deliverables from 24fps as the difference is so small.
I think its better than adding artifacts with pitch changing plugins. 24 to 25 is a different ballgame.

I use an app called Time Factory 2 that does both speed and pitch adjustments with very little amount of artefacts. Deliverables for a film of that caliber will include common frame rates as default. |
