They did say during the conference that the new chip had a new video encoder/decider, so that sounds plausible.

Maybe just more efficient since the A14 already had AV1 and HEVC support.

The cinematic mode is done by recording a depth map (calculated using the ISP and Neural Engine?) alongside the regular video. On older phones you could do this using the SDK, but iirc it was a much lower resolution depth map (like 480p or less?).

Given that they've also added ProRes encode/decode, it's likely fair to assume that they've redone the entire codec hardware.

So yeah, this is my long-winded way of agreeing with you that it is indeed more efficient.

Uh, I'm gonna need to see a reputable citation for that claim.

Yeah I tried to find another source and could not find anything. Does anybody else know? I just see a lot of posts complaining about CPU usage with AV1 on a M1 macbook.
