“This film may not be the one, but someone somewhere has got to advance cinema forward, otherwise nothing changes.”

If it ain't broke...

I honestly don't understand the need and fascination with all of this HFR business. Reading that article gives me the shivers.

Or "infected", as I would put it

What they need to do is abandon 24 fps as the standard format and adopt 30 fps. It's enough of a change to improve on pans and judder but not enough to cause the images to look like TV.

The original 70mm format (Todd-AO) was 70mm @ 30 fps (projection format - 65mm @ 30 fps shooting format)

Speaking of which, I recall it being floated in one article or another that they were doing this on Gemini Man, that it wasn't actually 120fps all the way through? Yep: https://www.screendaily.com/features...140383.article

I think this is what I was thinking of. They tested it but chose not to do it.

The filmmakers also had the option of alternating the frame rate between scenes but chose in the end to maintain a consistent 120 frame rate throughout.

“We learned in tests that if you start out looking at 24 and switch up frame rates the change takes you out of the movie. You get used to it after a few minutes but if you switch back down to 24 then it’s distracting. There are all sorts of creative reasons why you might want to do this for a particular story. Ready, Player One, for example, might work since you are moving between different worlds. But it wasn’t right for a more conventional drama like ours.”

They made the wrong choice. This thing looks like a soap opera the whole way through.

Thanks, fair enough, but the point remains that they can do this within the HFR 'container' by duplicating frames without actually physically changing the playback rate of the 'container' itself (which is not the same as actual VRR tech), so it won't be an issue for Cameron on the Avadahs if he wants to do it. As he'll likely be using 60p at most then the difference between the 24 and 60 stuff won't be so pronounced as on Gemini Man in going from 24 to 120, though Cameron shot T2: Battle Across Time in 30fps (on dual strip 65mm!) so it wouldn't surprise me if the dialogue stuff had a touch of extra temporal resolution to start with so that the transition to the actual HFR shots is less jarring.

good to see the author (https://collider.com/avatar-sequels-...james-cameron/ ) agrees visually with what I posted the day before his interview with James C. was published - https://forum.blu-ray.com/showthread...b#post16969054

Phoenix Model Market, DS Broadcast Team on HFR 120 Hz ATSC 3.0 Broadcast

PHOENIX—DS Broadcast has announced that it recently conducted an over-the-air broadcast of High Frame Rate 120 Hz video, working with the Phoenix Model Market project to do so. The company says the video was encoded by its BGE9300 encoder, received by its BGD4100 integrated receiver decoder, transmitted via a NEXTGEN TV transmitter from the Phoenix Model Market and displayed on UHDTV screens in the Phoenix area.

Typical TV video is transmitted at 30 frames per second, which DS Broadcast says can create a blur for high-motion activity like sports or scenes of waterfalls and ocean surf. NEXTGEN TV is expected to deliver 60 frames per second, but Dave Folsom, consulting engineer for the Phoenix Model Market project, says that 120 Hz is the “holy grail” for sports fans.

“This combination creates an exceptionally immersive experience, even with 2K video sources,” Folsom said. “It’s even more impressive than 4K video to the average viewer. And the combination of High Frame Rate with High Dynamic Range is also very efficient for broadcasters, consuming little additional bandwidth.”

It's sad and embarrassing when publications continually make mistakes like this. Yet again, peddling the canard that interlacing "splits up" only 30 images into 60 "half-frames" of a mythical 30fps original.

Whereas in FACT, for live broadcasting in the majority of cases, there are 60 DIFFERENT pictures per second, producing super-slick motion. 60 FIELDS per second does NOT mean 30 frames per second.

There are 60 different moments in time which are captured by the camera and displayed by the TV. Leave interlacing artefacts out of it for a moment, the motion is smooth because of this, and to imply that it's only 30fps is just a wrong

Michael Balderson should be thoroughly ashamed of himself for making such a fundamental error.

[sapiendut]

That’s a VERY bad mistake.

Possibly me, as I was speaking about the technical difficulty in performing it vis-à-vis the projector systems at the time (2016) - https://forum.blu-ray.com/showthread...e#post12781379

and in previous posts prior to 2016, as opposed to achieving the same outcome vis-à-vis the new introduction of TrueMotion software by Tony Davis.
