Why did nay-sayers dislike HFR on Hobbit: An Unexpected Journey? First off, many felt that the higher frame speed looked too real, revealing production flaws and ruining the suspension of disbelief. Worse, purists compared HFR to a cheap TV effect and called it vastly inferior to time-tested 24 fps. Though Jackson claimed to be unfazed by all the criticism, he did take it into account for Hobbit: The Desolation of Smaug. What audiences actually disliked about the first film, he felt, was not the HFR but the extra sharpness that resulted from filming digitally in 5K with Red's Epic cameras instead of film. To remedy that, he told Variety that actor-friendly "Pro-Mist" lens filters were used during filming to apply a slight blur and remove any harshness during certain shots. In addition, each scene was carefully color corrected to "take the (video-like) HD quality away" and he deemed the final results to be "reasonably successful."
To my eyes, those improvements did succeed in improving the oversaturated, oversharpened look of Hobbit: An Unexpected Journey. I was fine with action scenes in the first film, but often disappointed during slower dialogue parts thanks to sets, props and makeup that didn't stand up to HFR's unflinching gaze. Jackson's tweaks mostly allayed those concerns for me and I didn't notice any production design clunkers as I did in part one. Meanwhile, the 3D was magnificently integrated into the film and caused me no headache or other undue effects -- which was the primary goal of the filmmakers with HFR.
So what's the problem? The latest tinkering for Smaug can't change the fact that a lot of cinematic sleight-of-hand gets tucked under the rug by the older film tech. With all its motion blur and flickering, 24 fps projection adeptly hides the styrofoam, plywood and even digital effects used to create film magic. If you crank up the reality quotient by spooling more frames, however, such fakery is easier to spot. Though Jackson succeeded in smoothing much of that over in the second installment, at times I still felt I was standing around a movie set rather than watching a film.
Part of this problem lies in the nature of 3D itself, which invites you to look around the frame and "step into Middle Earth," as Jackson put it. During more ponderous scenes, I occasionally noticed sets or props that looked like, well, sets or props, that probably would've nicely passed for a sword or forest at regular speeds. In fact, Jackson and the studio elected to screen the film to critics and press at 24 fps so that they'd not get hung up on the technology -- an apparent drop in confidence on his part. As a result, few reviewers ended up catching the 48 fps projections, but one who did felt (a bit harshly) that he was watching a behind-the-scenes video, and not the movie itself. Would other critics have had the same reaction had they seen the HFR screenings? I believe there would have been more than a few rants, and Jackson likely thought so too.
Perhaps because of these follies, Peter Jackson and pal James Cameron are left as the main proponents of HFR. Bryan Singer, for one, thought about it for the next X-Men film but took a pass, telling THR he had "concerns about how certain sequences would look, and (the)... cost factor in rendering visual effects." On top of money issues, doing CG at 48 fps can dramatically increase the time it takes to finish a movie -- an ugly combo for filmmakers. If anybody was willing to take the plunge, extra profits are far from given, since many theaters screening Desolation of Smaug are charging the same amount for HFR as regular 3D viewings -- with no proof that it draws extra viewers. The net result is that the cash and time outlay for high frame-rates isn't worth the effort for filmmakers who don't have their own digital effects workshop.
From what Peter Jackson's said so far, the main reason for the existence of HFR is to make 3D better, which it undoubtedly does. Since he and James Cameron have played a large part in promoting 3D and getting theater owners onboard, it's therefore easy to see why they're also firmly behind HFR. They no doubt hope it'll help boost 3D audience numbers, which have declined steeply since the salad days following Avatar. Given the waning audiences, bad press and steep technical hurdles, I believe Jackson's last Hobbit HFR act will need to be as dramatic as the finale itself to save the fledgeling format.
