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.

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)

And frankly, Jason Momoa fatigue may also be a issue. Jason momoa playing Jason momoa, playing Jason momoa. Its like with The Rock playing the rock, ... Like guys, acting ranges?

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.

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.

This is entirely because of deepfakes.
Apparently Seedance has a version without guardrails if you are a licensed production company. I suspect Google Omni would too, but I don't know anyone who uses that model.

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).

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.

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).

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.

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.

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.

OpenAI has completely shifted focus, Google still is working on various toolings/models but ultimately most people are unwilling to pay for these generations, whereby code, can easily be burned (and paid for) by businesses.

Comment by chrysoprace 1 day ago
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.

If the concept of art one has in mind limits creative endeavour and acts as a gatekeeper to art, then it is probably better not to have a concept of art at all.

Generating large training video datasets for robotics is going to be huge. Google used generative AI to make training data for self-driving cars (Waymo). This is by far the most promising facet of this tech, IMHO, and hugely underestimated in potential future impact.

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.

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.

Look into photo editing where ai based tools can remove subjects, do generative fills and even transform 2d to 3d/video. Same will come to other ai art too. And this will again differentiate amateurs “prompt 3 lines” and pros “I have vision and I will pursue it using tools available to me”. AI is secondary here.
As I said before - ai helps to raise the floor, not ceiling.

> This is the same level of arguing that only painting is the real art and photography is just clicking the button
And my point was that these two comparisons aren’t the same. They aren’t the same because photography is an art form and so is painting. They both have essence that I think AI generated art won’t capture.
For example, if someone showed you a photograph of a buffalo that had a bird also in the frame on a fence post. How would you react?
Then let’s say they go “oh well, I actually photoshopped that in from another photograph I took.”
You might be a little less impressed but they still took this picture of a bird.
Then instead of them saying they cut and paste the bird in they say “Oh Photoshop generatively added that in.”
I think many if not most people would think that’s far less interesting than the other two scenarios. Maybe you don’t, and that’s fine.
https://www.nature.com/articles/s41598-023-45202-3 is a good read on this with regards to the “value” of art.
Comment by galkk 21 hours ago
If a director during montage or review will say: “that shot will be better if camera was 2 feet higher, we need to reshoot” or “that extra takes too much attention from main character, can we remove it digitally”, and the author will prompt the same to ai, for their generated videos (that I’m quite sure will be enabled in next years) - this is the same art. creative process is constrained by available tools, but they don’t define it.
Do you think that people posed for medieval family paintings at the same time?
I see your reasoning a lot in many areas, and in my pov it’s just a final, conceding attempt of gatekeeping.
Painters telling photographers that there is no soul in photography. Film photographers telling the same to digital photographers. Woodworkers telling that cnc’s are not woodworking. Musicians telling that only live music matters and recording doesn’t capture all nuances 100 years ago. Guitarists owning and used hundreds of pedals and amps telling that to digital modeling.

For painting, realism was really what made works great for a long time. Then photography came along and realistic depictions of things were no longer novel, so painting became about representing things in a more surreal way, and novel representations of perspective and emotion became great. Meanwhile with photography initially just capturing a clear image was impressive but now you need to capture something truly rare to have a great photo.
With AI I'm struggling to imagine what will be hard enough to achieve that it remains novel.

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.

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.
Comment by userbinator 1 day ago
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.

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.

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.

Such models will have fascinating use-cases. But "generating realistic content" is a comedic resemblance of realism movement in painting.
Comment by Cyan488 1 day ago
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.

(note that it's made by Bytedance; on iOS the search results seem to be copycats only) Doubao is https://www.doubao.com / Dola https://www.dola.com in English. There seems to be no way to find out how much a subscription costs without making an account.

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.

This feels like the serious inflection point for high quality full length feature film productions using this tech.

IIRC they give Seedance 2.5 yesterday. Byteplus API is the official way to access it as an API but I am not sure if they serve 2.5 yet.

I think the emphasis on using them for ads & monetizable slop is because they’re currently too expensive and thus usually need to be part of a revenue generating pipeline.

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.

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 ...

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