I dunno... I actually liked the HFR version of the Hobbit. Maybe it was because I like the hobbit better than any of the LOTR series which all put me to sleep. One problem I had with it was that several outdoor scenes looked way overexposed, I don't know if this was because of the HFR or just a way to balance out the additional dimness from the 3d. I don't think HFR will be the next "cinemascope" fix to change the industry, but I think it'll stick around for a while.

There has never been a film format that supports multiple frame rates in the same feature, that would be technically almost impossible to achieve. Every projector needs some time to accelerate or decelerate from one frame rate to another.

I do believe you are incorrect; if memory serves me, Maxivision 48 did have as part of its design, the ability to change frame rate within the film. Whether or not I am accurate about this, fact is, 35mm projectors are routinely outfitted with variable speed controls so they can properly project silent films at varying speeds, at times within the same film, to mimic the way handcranked projectors of the day sped up or slowed down scenes as Bajsic mentioned, but it's done today as well.

But my question still remains -- wouldn't the 48fps of Maxivision cause the same negative "video" look as digital HFR seems to cause? And if it didn't (Ebert seemed to orgasm over Maxivision 48), then perhaps it is something more going on than just the high frame rate. Same thing with ToddAO -- everyone seemed to gush when talking about what OKLAHOMA! looked like with they ran that 30fps print a few years back. So is it just something about digital PLUS 48fps that causes negative reactions that doesn't happen with film and 48fps?

Then again, maybe Joe is right, maybe Ebert loved it because he only had to watch a 15m demo and not a 3 hour movie.

I was able to find the Maxivision 48 pdf document on archive.org and it doesn't seem like this was a capability. They touted the "switchable format projector" that could show features at either 24 or 48 fps and could also do either standard 4 perf or Maxivision 48 3 perf (not clear if it could do 4 perf 48 fps).

One day I will peek at a HFR film but I think the problem with HFR is the goal is wrong. The goal should not be to make movies look real. 8k shooting/projection at 60 fps would probably be great for a theme park simulator ride where you are trying to make it look "real" but movies have "movie magic" that needs to be hidden.

The only "problem" I've ever noticed with 24 fps is the stuttering or whatever the technical term is on certain camera pans. I don't think it detracts that during a car chase the vehicles have motion blur. In fact it probably helps to hide the stunt driver's faces.

I never liked the look of the Jackson Lord of the Rings trilogy, but now they look like Ben Hur to me compared to the HFR Hobbit.

Many people have said the image looking too sharp and detailed, I cannot complain about that. I saw The Hobbit on a 62 ft. screen from a Barco 2K/RealD setup, and the whole thing looked soft, with less detail and sharpness than I expect from any 2K projection, comparable to a Super-35 originated film in a poor high-speed print (minus steadiness weave).

The first 45 minutes looked unbelievably cheap and ugly, after the dragon attack (video game without interaction)the sequence at Bilbo's home was nothing but bad cinematography, amateur direction and that cheesy interlaced 1970s TV drama look reminding me of The House on Eaton Place or Monty Python's Flying Circus.

The only part of The Hobbit where HFR added something (for me) was the escape from the Orc caves, here the higher frame rate made the flying camera shots and the fast action more exciting, although the business with the bridges and ladders is quite ridiculous and makes the old Indiana Jones lifeboat-as-parachute stunt look realistic.

To me, the combination of HFR and 3D looked best in dark scenes (Bilbo and Gollum in the cave) and worst in bright sunlight (like Radagast with his rabbit sleigh detracting the orcs).
Surprisingly, many battle shots did not have the smooth flow I would have expected from 48fps shooting, they did not strobe, but had a kind of smear - like the artifacts of converting NTSC to PAL, but definitely not the way one sees fast moving objects in real life.

Most exterior scenes had what I consider ugly colors, especially greens looking sick and artificial, highlights burnt out. Maybe the projection setup is to blame for this, I noticed some color fringing on white letters. It all had the look of light valve projection from the 1980s, smooth but always soft and very un-cinematic.

I really wonder if audiences will pay more for this in the long run.

Are they charging more for HFR? I thought it was just the standard 3D charge.

No, I checked it again - the price is the same for 3D and HFR 3D.

€ 13,40 ($ 17,70 / GBP 10,90) for 3D HFR & 3D 24fps
€ 10,40 ($ 13,70, GBP 8,48) for 2D 24fps

Mixed it up eith the added € 1,50 per ticket for RealD glasses because I forgot to bring my own.

Sure, many of those silent films predate any real fixed frame rates. But, the frame rate was not encoded onto the film itself and is at the discretion of the projectionist, following the instructions of the movie maker of course.

Still, I don't believe there ever was a format that allowed the frame rate to be automatically adjusted on the same reel or even feature, especially not from e.g. 24 fps to 48 fps, which essentially means double the speed. How would this ever work with sound? And how would this speeding up/slowing down look on screen? Especially, since every projector would have different characteristics regarding acceleration and deceleration.

Due to the lack of other feature films in 48 fps or higher frame rates, this question is difficult to answer. But have you ever been to Soarin' over California or the Floridian counterpart? That movie is essentially an IMAX film running at 48 fps.

To me, that movie doesn't feel like a normal cinematic feature, but it is not supposed to feel like one. It also doesn't feel like a soap opera. It tries to mimic reality and it comes very close to that.

Did this 62ft. screen have a RealD XL-DP or just a single projector setup? I guess having a single projector for a 62 ft. screen is really pushing it.

That's entirely up to the theater or chain. Most of the theaters around my area are charging extra for HFR actually...

If they are, they're stupid. HFR is a relatively cheap upgrade that requires no upkeep. I can see the extra charge for 3D since it is expensive to install and a lot more work. Charging extra for HFR is just being greedy.

Well, I've done my homework a bit and I found just two theater chains that charge more for HFR, so I'm a bit mistaken:

Kinepolis (from their Belgian site):
Supplement 3D € 2.00
Supplement HFR 3D € 3.00

Pathé (from their Dutch on-line ticket sales):
The Hobbit 3D € 10.50
The Hobbit 3D HFR € 11.50
Disclaimer: The shows start around a different time, I'm not sure if the non-HFR show still counts as a matinee.

All the others seem to charge the same or I just didn't find any relevant info.

I would qualify Kinepolis as extremely greedy. They were one of the first chains in Europe that went fully digital but they also asked an up-charge for a digital presentation. For a time, you could choose between 35mm or digital (It was marketed as HD, not really far off actually [Smile] ), but that choice, off course, went away after some time and the up-charge became the new standard.

It is in no way impossible to have different framerates in the same film. Let's assume you want to have 24fps and 48ps content in the same film. All you do is shoot 48fps and edit in a 48fps timeline and frame drop every other frame in the section that should be 24fps, and then double each remaining frame to fill in the gaps. You could even create a mask and have particular parts of the image run at 24 and others at 48.

That's the thing I proposed a few posts back. It only works for BaseFPS mod TargetFPS = 0 though.

Have you also seen it in a non-HFR version? If so, what did you think about it? Was the video/soap-opera look entirely gone according to you?
Yes, I watched a bit of both 24 fps versions (2D and 3D). The shortened shutter angle was immediately obvious to me. It makes for a distracting stroby look whenever there is fast motion on the screen – and there’s a lot of it in this one. And the problem gets worse in 3D, of course. It’s almost as if they made the 24 fps versions intentionally stroby to highlight the smoothness of HFR in comparison!

So it certainly doesn’t look like they added any motion blur in post for the non-HFR versions. The Benny Hill Effect seems to disappear in 24 fps, though.

Watched on a properly maintained setup, the 24 fps DCP is very sharp, stable and noiseless. But I fully agree with Christian in that a lot of the exterior RED cinematography is just plain ugly, no matter which version you watch. The combination of stroby motion, poor highlight handling, unnatural hues and sometimes flat lighting (check out the first scene with Bilbo and Gandalf) does add up to a cheap video look even in 24 fps. Still, it’s much more cinematic compared to the HFR version.

Anyway, I maintain that it’s the HFR itself that’s responsible for most of the soap opera look. Sure, you could make the colours prettier, but it would still be just a prettier soap opera look.

Sadly, I still haven’t seen any film-based projection faster than 25 fps. Perhaps a trip to Futuroscope in France would be in order one of these days. Since we’ve been discussing shutter speeds, it might be worth noting that any film-based projection will always have a ”shortened” shutter angle by technical necessity – a 360° shutter is only possible in digital. So by all reasoning, Maxivision should unavoidably suffer from the Benny Hill Effect.

Even Trumbull doesn’t seem to think that HFR is suitable for dramatic feature films, no matter whether it’s film or digital. Here’s a 2010 quote from the man:
quote:
I love high frame rates, because I like to make simulation rides and reality-based experiences that are looking to be as realistic as they possibly can, but 24 frames is what I call the “texture” of feature films. And I don’t think anybody’s really ready to see what you would categorize as a feature film shot at 60. And that was one of the tests I did when I was at Showscan; we shot a fully dramatic short film with sets, props, actors, the whole thing at 60 and it was very disturbing. Because it was like live news, or sports, or something.

I would really like someone trying to get that prettier soap opera look for once, just so we have a comparison [Wink] .

Are they still showing something in IMAX HD? I know that Phantasialand in Germany is running Race for Atlantis on an IMAX HD/OMNIMAX set, but that's a stupid animated movie and the picture is very dark and out of focus most of the times.

You could also shoot the 24fps sequences in 24fps, no need to drop frames or "create a mask" which has nothing to do with framerates but rather video with an alpha channel (video editor here, btw). But I would still very heartily recommend against switching framerates during a show. It would be very distracting, much more so than aspect ratio changes. It's a really, really dumb idea and not at all necessary.

You can create masks for all sorts of different reasons, not sure what you're talking about.

In this instance, the 48fps represents your base frame rate and the 24fps is your alternative speed. Lets assume you want to minimize blurring on the subjects in an action scene but what to leave the rest of the image with standard 24fps motion blur. You would lay the 24fps track on top of the 48fps track and create a mask that leaves the 48fps subjects in the frame but keeps the rest of the image as 24fps.

I've actually done this before for fun. You can also see examples of this with Doug Trumball's showscan digital.
