    As with many things concerning TVs I'd like them to be dumber. They shouldn't be interpolating frames in the first place. Just display the picture with the best dynamic range, and viewing angle you can at the appropriate frame rate. TVs shouldn't be smart. The article says the origin of motion smoothing was to counter the "judder" of the mismatched framerate of the TV and source. If they really wanted to fix it they should have developed variable framerate monitors like we now have with gaming monitors.

      TVs shouldn't be smart

      AMEN! 🙌

      Not only is there the absurdity of the fact that "smart" functions will certainly age way way way waaaaay faster than your actual display does. But I have yet to find the "smarts" in my smart TV to work very well at all. Plus the damn thing has to reboot every time it does a system update, which takes forever and leaves me TV-less the whole time. If my AppleTV is updating, I can just watch off an antenna or play a video game or something. If my TV is updating, ANYTHING plugged into it is useless.

      This then introduces the inanity of regular software updates for my TV. The idea of having my TV get bricked because the power went out in the middle of an update is a failure state I haven't had to deal with before, but thanks for introducing this fresh new risk for no additional benefit. Plus all these other fresh failure states we can have. Suddenly we gotta worry about hard-drives failing, software going corrupt or reaching end of life, compatibility issues with peripherals. They've introduced many of the headaches of owning a computer to something that used to be simple and straightforward.

      What's worse is, nobody is buying a TV with these computer features in mind, so we're not even bothering to vet the quality of the computer inside when we buy it. Who knows what sorts of long term impact this is going to have on the reliability of these things. I used to just have to worry about the power supply and the panel. Now I have all the headaches one has with maintaining a shitty computer. I would pay extra to have a dumb TV at this point.

      And don't get me started on the fact that my TV's OS now serves me ads and has spyware/bloatware pre-installed on it that I need to do extra work to remove. Whoever decided this was the next big thing needs to be dragged out into the middle of the street and shot.

It's the same problem with car infotainment systems, which is only now getting solved by auto makers supporting CarPlay and Android Auto out of the box.

        Why not just buy a 40"+ computer monitor? Most of the major brands have proper monitors that go above 40". The only downside of doing that is you will usually have to pay a bit of a premium for a monitor over the same sized TV though, since the panel standards tend to be higher and they come with more features, e.g. better colour gamut, contrast ratio, response time, frame-rates+frame-sync, multiple input types/ports, etc. However the mounts for TVs and monitors are usually the exact same (VESA) so you can just as easily mount a monitor to your wall as you can a TV, and most monitors still come with HDMI as an input option.

      This was solved over a decade ago with support for 24hz signals over HDMI. Any media player should be setting the output to 24hz whenever playing 24hz content. I can't fathom why this isn't used more widely. About the only consumer devices I see that use this by default are blu-ray players.

    I would have liked some examples, demonstrating the difference between higher and lower frame rates. The article contains a video, with a few seconds of a scene from one movie (and it wasn't a good scene). I want to see this effect with both versions side by side for comparison. Because I don't know what they're talking about. I don't know if I've ever seen it - and, if I have seen it, I don't recognise it as this "motion smoothing".

    That said, I have noticed something off about televisions on display in shops. When I watch them, the pictures just seem wrong. I compare what I see on the screen with my normal vision of reality, and the images on the screens seem less real than reality. They're too clear, and too bright, and too artificial. I'm not sure I'd want to watch TV like that at home.

        It's not so much that they are changing the settings to do that so much as TVs are coming set this way by default now. Motion smoothing is not the only feature I have to turn off whenever I buy a new TV. Almost every single one of them has a whole host of 'enhansement' features like 'dynamic color mode' or denoising or sharpening algorythms and the like. They also tend to have BS adjustments like "color" and "brightness" which exist only to degrade the picture.

        Some higher end TVs don't have these defaults, but will start off in a demonstration mode instead, which at best will show you the difference side-by-side and at worst just turn all of those features on until you disable the setting.

        Manufacturers keep putting these features in their TVs because they think that it will help them increase the price of their products. In the meanwhile, I am perfectly willing to spend an extra $100 on a TV with analogue inputs that don't display like complete garbage.

      That demonstration video actually made me feel physically ill and made me feel strangely anxious.

      Honestly, I get it for live action. It makes sense to want to see it like reality. But animation in particular seems to be a bad choice for it. Animation is a medium where every frame is ordered in a specific point in time - an artistic choice. The varying framerate of animation is used as a creative tool. Just take a look at Triangle Production's animation; they use 3D CG throughout their production and could just as easily produce a 60FPS version of their shows for a relatively minor investment, and it would have also cost them less manhours since they are no longer worrying about which frames to render and how to put them together.

      That being said, I've seen my share of poorly transcoded anime releases with choppy camera pans, so the effect is not completely lost on me.

            I see, I'm not denying that it can be used as a creative tool, but I do believe that in a lot of cases there is a factor of cost involved. With 2D, hand drawn animation, the animators would need to animate like 2.5x the frames, which would certainly be expensive and difficult.

            The benefit of fluidity that I see from frame interpolation is more important to me than preserving artistic choices made using variations in framerate, which I would hardly notice anyway.

            Also, I'm not sure if frame interpolation actually impacts those variations to the extent you might think. Since video files can only have 1 frame rate, 12 fps in a 24 fps video is usually done by duplicating frames, so frame interpolation wouldn't completely remove the effect, as it wouldn't interpolate between identical frames.

        Yeah, animation is weird. One example I thought was really interesting lately was Netflix's The Dragon Prince series. Exactly like you're talking about, it's created with 3D animation, so they could have had any framerate, but they specifically chose to use a low framerate to try to emulate hand-drawn animation:

        Animating in CG allows us to have more dynamic camera angles and lighting, and much more detailed character models (which I'm super happy with)! But one of the dangers of animating in CG, especially when you're moving at a break-neck TV schedule is that the characters can look "floaty." To correct this, we looked to lots of anime (including Miyazaki) and noticed they draw 8-12 frames per second (instead of 24 fps, which is closer to Pixar, or Disney feature.) We asked our animators to emulate this approach. The result can look staccato (or choppy), but offsets that "floaty" feel.

        We're aware not everyone loved this decision. The good news is, this kind of thing can be "dialed in" if people felt we went too far. That is assuming of course, we make more episodes one day.

        (source)

        It bothered me regularly while we were watching the show, because many of the animations would be choppy in a weird way and I'd feel like I was watching a show on a poor connection where frames were being skipped. My wife didn't even notice it though.

          Personally I think lowering the framerate of CGI to look like hand drawn animation is a crutch. If it doesn't look enough like hand drawn animation at 24fps (or interpolated up to 60), it's not going to look like hand drawn stuff at 12 fps, it's just going to look like choppy CGI. At least in my experience.

I feel anime just looks so much better with interpolation that makes things so much smoother and removes a bunch of the coppiness.

    Motion smoothing is awful but every time I’ve turned it off on someone’s TV, they’ve just complained about it and wanted it switched back on. Most people are, as the article points out, just used to seeing content that way.

    One thing I disagree with the author about is Billy Lynn’s Long Halftime Walk. I haven’t seen it in 120 FPS, but I do have the 4K Blu-ray, which has a 60 FPS version. It’s absolutely incredible. I loved seeing such fluid action (that wasn’t interpolated from other frames). So I can only imagine what 120 FPS must have been like. One of the reasons I’m so psyched for Avatar 2 is that I want to see a 120 FPS movie in theaters.

    Good write-up on motion smoothing and I agree that it's a problem. Mainly I'm just posting to say how heartened I am I to see how many in this thread are dissatisfied with the "smart" TVs on offer today. The industry-wide practice of selling only those, with no "dumb" alternatives, is one of the most anti-consumer practices today that I am aware of. I really hope the sentiment I'm seeing here indicates a growing trend that might lead to change.

    If just one manufacturer experimented with a line of stripped-down, offline-only TVs, I think the market demand would speak for itself. I'd pay a premium for one, if the price were uninflated and reflected the cost of the hardware vs. what you pay after adware subsidies.

    The thing that gets me is, TV display tech has come a long way. You can get a gorgeous 4K OLED with HDR in a (very thin) 55+" form factor. These are screens meant for living rooms, with multiple input ports and remote controls. Sorry, but a fancy computer monitor is not a perfect substitute. There needs to be a way to purchase a great screen like this, with none of the added junk.

    Motion smoothing is considered a plus for watching sports, and, in a time where we consume more and more of our media via computers and smartphones, that's what companies are focusing on. Regarding the soap-opera effect on 24p/30p films, most people simply don't care. If I changed my mom's 4K for a 720p that is identical in everything else, I'm convinced she wouldn't even notice it.

    In the old days, we used to complain about the aspect ratio, a much worse issue because it was impossible to revert it on the consumer's end. It literally took chunks of the frame away from you, ruining entire scenes. I'll be happy as long as I can disable all digital enhancements. The Godfather doesn't need any simulated frames, thank you very much.
