    The quality is quite high, but an observation is the direction they're taking these models correlates heavily to the usage demand of China vs the West. Specifically, they're immensely focused on t2v for action / high effect shots. There's one human reference shot in the entire release page, and that one doesn't focus on dialog at all.

    For filmmakers I've talked to in the US, one of the biggest demands they have is v2v where they can carry over an actor's performance and insert it into whatever world they want. The movie market in China is somewhat different though - it's heavily oriented towards high action / high special effect movies. Consider this list of hollywood movies that have flopped in the US, but did great in China:

    Warcraft (China: $225m box office, US: $47m)

    Resident Evil (China: $159m, US: $27m)

    xXx: Return of Xander Cage (China: $164m, US: $44m)

    Pacific Rim: Uprising (China: $99m, US: $59m)

    One read of this is that action movies / visual spectacles translate more universally than dialog-based movies. Another read is culturally China prefers that type of content in general. I suspect that for Bytedance, their focus is on action / special effects because thats where they see the demand.

      China has a population 4 times bigger than the US, and the films you cite did roughly 4 times better in each example.

        The countries' box office markets are about the same size, though:

        https://en.wikipedia.org/wiki/Film_industry#Largest_markets_... ("Largest markets by box office revenue")

            United States and Canada $8,870,000,000  2025[175]
            Europe                   $8,200,000,000  2024[176]
            China                    $7,400,000,000  2025[177]

        But how much does ticket cost in China compared to the US? (Genuine question)
        • Sayrus 1 hour ago
          Anywhere from ¥20 ($3) to ¥100 ($15) in large cities. Depending on the city, type of ticket and whether it's China-exclusive or worldwide release. Looking at prices, ¥40 doesn't seem like a bad deal.

      It's not about cultural difference but simply what's easier.

      Action sequences are forgiving. There's lots of motion and shiny vfx to fudge things over. Rapid cuts mean each shot can be short enough that the inevitable accumulation of AI hallucinations from frame to frame doesn't get distracting. Sets can be generic: if you're generating robots attacking New York, the viewer isn't going to have time to track if the bodega on the corner is in every shot, or if the Chrysler Building switches place around town. Shots can be practically from different cities and nobody will notice.

      Carrying over an actor's performance is the opposite. You want long shots and impeccable scene stability. You can't just throw some additive-blended particles on the actor's face to distract from its generation deficiencies, like you can do for the Marvel scenes.

      Bytedance is a corporation looking for clout, not to help filmmakers. They're releasing a model that makes them look good, and action sequences do that.

      It's a counterintuitive thing to viewers who have long been told that vfx is the most expensive kind of moviemaking. With gen AI, these somewhat convincing Marvel pastiches are trivial to produce, but a sitcom episode is utterly impossible.

      I hear this a lot, but I observed this is no longer that simple.

      Like Green Book (2018) made over US$70.7 million in China.

      And one of the most popular films in 2021 was Hi, Mom (2021), made over US$785 million.

      Obsession (2026) is another one that is doing amazing in China, absolutely beating high action films like Supergirl ($12 million and going vs less than $1 million)

      • HlessClaudesman 7 hours ago
        Supergirl is basically a lazy slob who is born with godlike powers, I can see why that doesn't play well in a culture that prioritises hard work and self-discipline.

        I haven’t seen the movie yet but I’ve been a subscriber to the YouTube channel of Curry and Cooper [1] for a long time. I’m looking forward to watching the movie.

        I wonder how many of the other people that went to see Obsession were already fans of Curry and Cooper.

      hong kong films is the mirror image of hollywood and fantasy/action are a lot more popular than american.

      But you're probably just blundering with value comparison since just per capita, your numbers arn't that' extreme, still the point stands.

      • DiscourseFan 12 hours ago
        I think it makes sense that historically American film focused on narrative based dramas and slow burn horror. Think of classic Hollywood hits such as Citizen Kane and Psycho. This is even apparent in the recent success of Obsession, which really follows strongly in the trend of Hitchcock, magical realism, human drama, psychological horror.

        Compare this with historically successful Honk Kong films: Kung Fu Hustle, Police Story, Ip Man. I mean there are examples of Hong Kong films that are slow burn human dramas, like Chungking Express and Eat Drink Man Woman, and successful American action films like Diehard, but I think its clear that Hollywood film didn't start out with action movies, and Hong Kong film didn't start out with slow burn dramas, but adopted these genres afterwards; you could even claim that successful Hong Kong films like the Bruce Lee films of the 70s fueled the American appetite for action in the 80s, which was the most prominent era for that genre in the US.

        As a corollary to this, it becomes clear that the Korean and Japanese film making industries are not as culturally distinct from Hollywood as Honk Kong film making is. For Korean film, the reason is obvious: Koreatown in Los Angeles is right next to Hollywood, in some respects is a part of Hollywood, and there are deep ties now between the Korean and American film making industries for that reason, and Korean-Americans have an overly high degree of representation in American media, and Korean productions often come to America to shoot (think of the end of Squid Games: it's almost certainly the case that they shot in LA because a producer has a cousin or something that works in Hollywood).

        They have support for long format and the industry is already attempting long shots with Seedance 2.0 which cannot be efficiently done without drift in other leading models like Kling.

    Whenever I see the new releases around video generation (and image) generation models, I get goosebumps, because it just feels so fun to work with them. But then I remember that I spend upwards of $10k on inference generating well over 50k images for storyboards, training models; and probably creating almost an hour of video (I assume). Yeah, I get that things can be economic if you don't use the latest models (ran some case studies on this), but the latest models are the most fun to work with. It doesn't scale as well as "vibe coding" stuff together on the weekend. And when things work really well its almost as if you're seeing an zoopraxiscope come to life for the first time; and you just want to keep going.

    I got a few offers to work with some startups in this space, but it also seems that many startups work on stuff that just doesn't seem to be very worthwhile (like creating masses of spam for YT or TikTok shorts), or even straight out morally/ethically wrong (cloning/deepfakes, etc). But seeing advances in this space; and coming from a filmmakers background, I might just end up being naturally drawn to this space on an engineering level and figuring something out along the way. As you can see I worked on a lot of stuff just for the fun of it, and documenting the process: https://edwin.genego.io/blog (but I stopped at the beginning of the year .... might.. just pick it up again.

      I went to Art Center for film. Loved it. But ended up writing software instead of shooting movies (while still also handling a lot of visual art direction, graphics work, UI, 3D animation, etc). Now I feel like we're starting to be roughly in the same boat as far as using prompts.

      What bothers me is that every piece of content generated this way helps flood an already saturated market for content, while slowly degrading the expectations of what people see, to the point that no one will bother with shooting or animating anything anymore. Even if it's 50% worse, it's 90% cheaper, so the economics argur against producing any new physically made content. Simultaneously, it's cannibalizing all existing content. This points toward a feedback loop, like a snake eating its own tail. And even though Hollywood blockbusters have followed that pattern for a couple decades, it's demoralizing to me to see it enshrined as the future of film (or to hear from someone who makes films that it would be a preferred mode of creation).

        That is an unfortunate pattern I fear is become applicable to a lot of domains (film, software, food, clothing, built environment, electronics, physical goods et al). AI is just accelerating that in a few.

        I feel these tools are destined to be mostly used as content generators - I'm happy to be proven otherwise but they've been around a while now and aside from a few pop videos I've not seen stuff that seems to be infused with the outer edge of quality art direction - perhaps because the model data limits it or perhaps it's the way they're used.

      MiniMax H3 is going to release weights. You can locally run it with definitely less than $10k (and possibly faster than Seedance's queue), and it's fun to train it for whatever you need.
      • pwython 11 hours ago
        H3 results are underwhelming compared to LTX 2.3 so far:

        https://www.reddit.com/r/StableDiffusion/comments/1vciy35/lt...

        Perhaps refined ComfyUI workflows will squeeze more quality out of it, but it's definitely not in the realm of Seedance, and Lightricks is training LTX 2.5/"LTX-Next".

        • dagaci 4 hours ago
          Note: Those results are a little misleading the good LTX results were generated with a good workflow in ComfyUI, and a prompt expanding local model.

          Whilst the H3 result was generated with the raw api using his raw prompt.

          If you ask ChatGPT or other AI model to "improve" your prompt (with cinematic, good lighting) generally, you will get also very good result from H3 also.

          My own H3 test show that H3 (API edition) is undoubtedly better than LTX in prompt adherence ! The real comparison will be with the edition of H3 we get to run locally.

    • weitendorf 12 hours ago
      I've been dabbling in this space on the application layer and have spent a few hundred myself experimenting with video models.

      It can be really entertaining/addicting to build with them because you're essentially pulling the slot machine and having TikTok/Marvel/YouTube come out of it. I think that was the bet with Sora but the problem is mostly that the novelty wears off quick, and most people want to just consume content without typing in what content they want to see, or sifting through mass-generated spam "content" with nothing behind it to make it worthwhile (a lot of people engage with content parasocially)

      Once the tools for creators to steer and integrate models in this space get better, it will explode. We've been working on what I think will be one of the first use case for integrating these models, because I think we're approaching a middle ground where they can be integrated in experiences to provide entertainment/engagement/fun experiences without feeling like slop.

      Btw, I'm impressed with some of the AI content on your site but I think you might want to pare down the non-demo pages because it has a different impression me (can I trust that this text is true? / I'm reading a lot of words but not really learning about this person) than you might have intended). I'm a bit of a hypocrite here but also speaking from experience.

      • Genego 12 hours ago
        Thanks for the input! And no I agree with your assessment of the website, I have some plans of a much simpler redesign soon, and I definitely value that critique. I think my "digital garden" has been through at least a few dozen of iterations, and sometimes I just get too carried away with it. The good part being, the next iteration always starts out better than the previous one (or at least I hope so :)).

        There were tons of continuity errors, but I suppose bad film makers make those too and often get away with it. The worst was the gift that was boxed in one shot, then open and containing a gift that didn't fit in the box. Another more subtle one was after they bumped into each other they were standing in front of a wall suggesting she just ran out from the wall.

        • weitendorf 12 hours ago
          Right now we're going through multiple concurrent but slightly non-overlapping transitions where AI is almost good enough for something, and seeing a predictable surge of spam/bad quality crap people don't like, followed by a whiplash effect when it reaches human or superhuman levels of performance.

          I think most developers would agree that the Cursor vibe-code era sentiment towards AI for coding was right in the sense that it wasn't that useful then, and a lot of people did and do stupid things with it, but it really did deliver quite substantially on its promise just a couple years after the "consensus" was often "that's never going to work".

          It's very strange to me how consistently public opinion shifts on this problem. In the long run we're all dead but whether it takes one or five years, you probably will be there to live through it. I assume whoever is downvoting you is just thinking with their consumer-brain or "I don't want that" (the way it is now) rather than that this will be no different than video games, or wasn't a child who watched youtubepoop or other weird stuff because it was funny.

      People are still figuring out the social norms surrounding "deepfakes" and I'm convinced there are some versions of the future where it becomes normalized for content under essentially fair use/free speech doctrine, and many where it's used to restrict free speech in the small number of jurisdictions where public figures would currently be allowed to be featured in this content.

      Obviously there are a lot of ways it shouldn't be used but I want to live in the future where it's something we use to have fun, where reasonable, rather than a dangerous/sketchy taboo

        The lack of creative understanding is astounding: all these generative media AI are fantastic for education applications. Sure, the vast majority want to use them to jerk off, but that's what humanity does anyway. Education is where these are extremely useful, and that is for the aid in conveying understanding to those that need the Jazz Hands of an image or audio or a video presentation to grasp the concept they are not.

      The only "harm" is from the authoritarians wanting to ensure only they have the means to produce propaganda for the masses.

They didn’t have the skill to make a convincing fake video themselves but if tools are at their fingertips… temptation.

        Really not ideal although obviously amazing artists will do incredible things with the technology that many of us will enjoy.

      While I generally think it's balanced against a lot of negative applications (misinformation, deepfakes, etc.), there are some good applications. I think regulation just hasn't sufficiently caught up with the harm they can cause.

      To give a good use case (audio generation specifically), the 2002 game Morrowind has had a resurgence lately and it's a really great game, but it lacks fully voiced lines for dialogue. A community project called Voices of Vvardenfell uses ElevenAI to generate voice lines from the voiced lines that do exist in the game. They don't take away jobs from artists because it was a monumental (unpaid) undertaking from community volunteers to do this before (there was such a big project but it was abandoned last I saw).

      So as with any emerging technologies, I think it just needs to be properly regulated.

            Oh I wouldn't trust myself!

              In his study, "Nearly 2,000 witnesses can be wrong", Buckhout performed an experiment with 2,145 at-home viewers of a popular news broadcast. The television network played a 13-second clip of a mock robbery, produced by Buckhout. ... The people at home could call a number on their screen to report which suspect they believed was the perpetrator. The perpetrator was suspect number 2. ... Approximately equal contingents of participants chose suspects 1, 2, or 5, while the largest group of participants, about 25 percent, said they believed the perpetrator was not in the lineup. Even police precincts called in and reported the wrong man as the one they believed committed the crime.

        Wait, but you compare the cost of animated show or a movie which is in its final, acceptable quality!

        The cost of that $15 per 30sec is NOT FINAL - you'll pretty much end up deciding you want another take - either due to some inconsistencies, non-physical movements, or anything else, which screams "that's fake".

        So the cost is most probably much higher; how much higher? We don't really know, as there are virtually no acceptable shows created by that tool yet (until there is something I don't know about).

          Thats true for grok and other models. You need to generate endlessly and cut endlessly and stitch them up together.

          but for seedance you pretty much get stellar output which is extremely consistent in a single shot. Like there is a very good chance you will like what you see.

          My experience with AI image generation is---

          If you want something vague and generic and don't particularly care about the details, then maybe you can get want you want on the first try, but you'll likely just get what everyone would call "slop".

          If you have something very specific in mind, then expect to spend several dozen generations before you get what you want, or something close to it, and then you may still have to spend more time making final adjustments manually in an image editor.

          ...and this is just for one image. I have not tried AI video production yet but I imagine it would involve considerably more effort.

          $15/30s is $1800/hr, so assuming 1/10 generations are good, that's $18000/hr for final content. A few orders of magnitude below professional movies for sure, but still not trivial.

    This seems extraordinarily good to me, compared to what I've seen before. Their washing machine advert example seems like it's as good as anything else on social media. I'm shocked by the quality and the coherence they're able to maintain, I assume it's really good at using those reference images they mention in their prompts. I think the only one that's noticeably bad is the concert hall, where the first few seconds show almost empty stalls and then toward the end it shows a full audience, and that audience also looks a bit off.

    It has improved a lot, but these demo reels still have all AI video issues. Flash cut salad (including the scenes that should have longer cuts), unnatural motion that looks animated, unprompted YouTube-face acting, etc. Admittedly it's all a lot less pronounced in this version.

    What is much more interesting is how well it behaves off distribution (e.g. how far it can deviate from that movie/trailer aesthetics and still stay coherent)

      Good spot, but the AI tells are getting so so much harder to spot.

      If I had to guess, models have producing content that is, for most of the population, indistinguishable from reality for at least 6-12mo.

      Very few people will watch a video frame by frame to pick up on or check for artifacts, especially in the places most of the population watch video (tiktok, Facebook).

      I have no doubt that, just like the fast corrections to 8 fingers, the final edge cases like reflections are being ironed out in future model training.

    You know what, in my previous life as a filmmaker I could've only dreamed of such a thing. Filmmaking is an art form which you cannot do alone. Outside of a lot of time and money, you need cooperation of a number of people and each day of production you end up accumulating a set of compromises to your vision. Your taste is what makes you tolerate that or not, and it's exhausting. It matters if you're the author since at the end of the day it's your name on it, not the crew (as much).

    Now that we have these tools, I don't know but I am absolutely disinterested in it. Not that it doesn't feel right or anything, but I'm just not excited enough even to want to try to materialize some of my "big game" stuff. Closest thing I'd compare it with is like when you pirate a bunch of games and you play none as a result of abundance.

    Weird-ass times.

    • cautiouscat 11 hours ago
      I think for me it's just missing the "essence". Making a film is hard, but that labor with multiple people who are passionate about the project is just as important as the end result.

      I've been trying to generate concept art for a game idea. I figure, I can't draw so why not have something else bring my vision to life. After dozens of failed attempts and burned tokens I decided to just hire someone. The experience was night and day. They provided thoughtful details to help tell a story in the image. They got to tell me what they added and why, etc. This isn't even their project but their passion for it showed in the end result.

      These models are impressive, but I think people watch movies because of the essence as much as the movie itself.

      • galkk 6 hours ago

          It isn’t. Photographers take the time to seek out things they want to photograph, decide how to compose the shot, maybe pick a subject and have them pose certain ways. Choose their lighting and color grading. That is their essence.

      Was just going to say... Even if all AI gives me is the opportunity to bring my visions to life even somewhat terribly... That's a lot better than I'd be able to do without it. Which is for them to go nowhere. I'll take it.
    • zmmmmm 14 hours ago
      The thing is, it has the same essential property that you don't control it any more. The problem with these tools is the lack of fine grained control means there is no room for you to express your individual creative input. Your total input is a few sentences of a prompt, then the AI did all the creative part. If the creative input is what you enjoyed, it is actually not that much more (or even less) here than it was with traditional film.
      • galkk 6 hours ago
        It will change soon. Ai is enabler. Again, as with photography and especially digital photography- everybody can click button but not everybody is photographer. Ai helps to raise the floor, not the ceiling

        Another aspect is that if you struggle and struggle and create something great, people can see the work you put in, and you'll visibly stand above the rest who don't have the same level of perseverance. But if anyone can create big studio quality visuals with a prompt, how do you stand out? "When everyone's super, no-one will be."
      • BoorishBears 13 hours ago
        I often see this kind of passive-aggressive characterization of the process with AI that's meant to bait people who obviously are expressing their creativity with these models.

        I hope no one will fall for it: even when you emphatically reply "I spent the last year building the pipelines I use" it'll still be treated as equivalent a couple of sentences relative to the old ways.

        -

        At the end of the day, the painful lesson some people are (re)-learning is that creative expression doesn't have to be tied to any specific process. A lot of people fall in love with creative expression + process... but some fall in love with just the process, and some fall in love with creative regardless of the process.

        AI does not favor those of us who loved the process (that's me with coding), but it's definitely capable of allowing new people to experience what it's like to have creative input in your mind and see it expressed outside of your mind.

        • plastic3169 5 hours ago
          Often in making art you need to love the process. Otherwise you’ll never get good enough. Most filmmakers don’t even watch their films after they have spent years with it discussing, planning, shooting, editing etc. There is lots of travelling, new friendships, comradery involved and in a way it becomes the whole scaffolding of your life. Replacing this with prompting is probably not interesting to this particular group of people, but might be appealing to completely new set of people.

          There are people who love coding and really dislike vibecoding, but atleast coding and prompting are the same mode of activity (typing in to a computer) so you don’t have to change your whole life to move from one to another.

        • zmmmmm 13 hours ago
          I completely agree with you. The question is, are we headed to a situation where it is a new process that still allows the same expression, or is it fundamentally less able to facilitate that expression? we have to get beyond the one-shot style prompt shown here to something much more fine grained. The jury is still out for me on this, but I can believe we will get there. We just aren't anywhere close to it right now.

      Speaking of the eighties, special effects were still done without CGI and typically on the cheap. That didn't make the movies and television series any less fun to watch. In the end it's about what people do with the tools, not the quality of the tools. People commenting on how these generated videos are not perfect or are getting some details wrong, look at some blockbuster movies from last century. It's very easy to spot the special effects. And it did not matter.

      But yes 80s science fiction is now science fact. Talking cars like in night rider are now definitely a thing. Some can even drive themselves. The robots in Buck Rogers, Star Wars, etc. look clumsy and fake compared to the real humanoid bots we are now starting to see. More close to I Robot, which when it came out 22 years ago was pure science fiction.

        Unfortunately it doesn’t apply to everybody :( Babylon 5 was mind blowing when I was a kid, and today the space and other sci fi parts from there, when I see them on YouTube, are quite cringe.

      it seems perfect for that - maintaining coherence over 30s-1min type window is achievable and so many ads are built on unrealistic premise to begin with.

      To me, just reducing the cost alone seems secondary, far more important is putting the actual creative and marketing people directly in control of the output. Maybe the end result still gets sent to a pro studio for final production, but letting the true stakeholders directly create what they want could be a killer app. It may also be a terrible idea, like Homer Simpson's car - but that won't stop it being successful.

    Much like the widespread availability of cameras has caused a massive increase in photos of things that would otherwise not have been photographed, I think widespread availability of AI video/image generation will cause a massive increase in media from everyone who wants to show their thoughts to others.

The popularity of AI parody videos is a sure sign of things to come.

      I think that will remain the use case of these tools as long as it is still so easy to tell they don't represent reality very well. Maybe that's a good thing, maybe we're not ready for a world where any video longer than a brief clip is indistinguishable from reality.

      Also, much of the promotion of these tools come from a population of people unhappy with the current state of the real content creation industry that use real footage and real people because AI movie promoters see traditional media as mainly propaganda machines anyway, so these tools sort help level the playing field.

        Unironically, it might be more ethical.

          Only if you don’t think about it for more than two or three seconds. Then you remember deepfake revenge porn and elon musk style child sexual material.

            What about "beefy animal men pin-ups" and "ideal body self-deepfakes"?
    • fursgonemild 14 hours ago
      Of course not. You can use them to make objectively silly fetish fodder, too.

      I belive thats what it WILL be, its heavily used in scammy and poltiical bullshit currently, but its only a matter of time until the cost vs benefit makes sense for hollywood and companies to start using it for actual commercials and tv shows and special effects etc for major videos.

      I get entertainment value out of watching the videos other haves created. I hear of educators creating educational value from the videos they make as it allows them to make higher quality explanations.

      Unlike the coding models it seems like the generative art models do a lot more harm than good.
      • sho_hn 14 hours ago
        I've been having some similar thoughts lately about some application spaces being more harmful than others.

        Coding, for example, seems somewhat benign, because code has to fulfil clear metrics: Either it works or it doesn't. Either it performs or it doesn't. As long as you are able to provide those metrics, you can to some extent treat it as a black box without losing much from a system view (lifecycle, long-term maintenance, keeping things working, broader qualified efficiency like re-use are of course other stories).

        But on the other hand, delegating decision-making and thinking to models feels plain harmful to me. I have so many stories around me from office settings these days: "We have to pre-pone meeting XYZ, and we don't have enough time to prepare, so I made this AI analysis <power point deck>". This was then mis-prompted to fit a foregone conclusion, no one has time to do it or capacity to refute a 2000 word slop deck (except by slopping back), and crazy stuff becomes plan of record. This is really going to be a problem for organizations ...

          > pre-pone

          That is an Indian English word, most non Indian English speakers are not familiar with it. reschedule or bring forward would be more appropriate for a global audience.

            I'm not Indian, and I see it used quite a bit by non-Indians :-)

            I also don't think it's difficult to understand given the prevalence of "post-pone".

      It's just you. Any director, storyteller, or filmmaker can see the potential here to realize scenes that simply wouldn't be possible otherwise. But indeed there's plenty of slop coming out too.
