Now I'm curious how the film would look if it was rendered in Cycles, there are some lighting aspects that really feel "off". Perhaps now that the film is acclaimed they could release a remaster done in Cycles.
deng
First off, switching to Cycles is probably quite a bit of work. While the renderers are supposed to be interchangeable, since AFAIK Cycles supports more features than Evee, options that previously did not matter with Evee rendering now have to be set for Cycles.
Also, having seen the film, I found the "unrealistic", cartoonish look very much to be a creative choice. Evee can produce much more "realistic" renders than what you see in the movie, but this requires also much more investment into things like assets and textures, otherwise you quickly land in the uncanny valley. So I think switching to Cycles probably would not matter much, unless the creators would also change their creative choices, which would result in a different movie, but not necessarily a better one.

What's odd in Flow is the contrast between the near-realistic non-animal rendering, and the non-realistic animal rendering. It didn't bother me much - it was clearly an aesthetic choice - but I know people who were bothered by the contrast.
CSSer
This is arguably true for all director’s cuts and remasters ever released.
Fluorescence
I kind of hope they don't. I like the humble, democratic, FOSS spirit - it's like Dogme 95 / "Vows of Chastity".
"rules to create films based on the traditional values of story, acting, and theme, while excluding the use of elaborate special effects or technology. It was supposedly created as an attempt to "take back power for the directors as artists" as opposed to the movie studio."
https://en.wikipedia.org/wiki/Dogme_95
I had a negative initial reaction to the animation style but it hooked me in and blew me away. It had virtues far more vital than render quality. In contrast, I bailed on "Inside Out 2" and have no interest retrying. I hope more people are encouraged to create lofi meaningful movies instead of thinking it's the preserve of billion dollar studios and sweat-shop animation factories.
jancsika
It could be revelatory.
Like the first time I played Super Mario Bros. on an LED screen. Finally I could see each pixel clearly, exactly the way the original artist didn't intend!
Edit: in all seriousness, this makes me wonder: has anyone ever re-orchestrated Beethoven's Fifth? Say, in the orchestration style of Ravel or Strauss? Someone must have done this, even as a joke, and I'd love to hear it. (I know about the "Fifth of Beethoven" disco tune which is great, but that's not what I'm asking about.)
alanvillalobos
Somewhat in this vein is Recomposed by Max Richter: Vivaldi – The Four Seasons. I liked it, but I am definitely not a purist.
Neywiny
Haven't watched yet but that was my gut reaction. When the engine first got stable released I tried it and was impressed at how quickly it got to a 90% solution, but the now complicated lighting scenarios that it couldn't handle took me back to cycles.
eurekin
Cycle's renders are beautiful, but 10 minutes per frame can be a hard sell... I wonder, if anybody tried rendering in cycles to output eevee's primitves. I remember that was one of the tricks that architecture rendering community used - just paint with lights in places that a full blown global rendering/path tracing would do.
Joel_Mckay
That is a common assumption, but there are ways to get your PC to do better:

Blender has a lot of other problems, but CUDA/Optix support is there for reasonable hardware =3
teruakohatu
I am out of touch with the latest and greatest Blender features. If best/highest fidelity renders are required, can Blender scale with a render farm?
Last I heard that was the advantage of the propriety/in-house alternatives.
hamaluik
Yup! https://www.sheepit-renderfarm.com/home Is a great community example of this.
ad-astra
I made my own distributed render orchestrator that supports Cycles + custom plugins. It uses Modal’s cloud compute APIs to spawn jobs on up to 20x containers with an L40S GPU (like 80% as fast as a 4090 with tons more VRAM) each. It ain’t cheap but it’s absurdly fast, and much easier in terms of cash flow than outright buying the equivalent GPUs.
https://github.com/stoicsuffering/distributed-blender-render...
orlp
An 1.5 hour movie at 24 FPS has ~130k frames to render. As long as you have less machines than that the parallelization is essentially free.
zoky
Any embarrassingly parallel task can scale almost infinitely by throwing more resources at it.
touisteur
I think I've seen some amazing Blender hacker put Cycles to the test on a machine with both NVIDIA and Intel GPUs. Love it that their API seems that portable and able to parrallelize on heterogeneous hardware. Amazing software work.
sangnoir
IIRC, the Blender Foundation's Open Source movies have been rendered on render farms from the very first one, produced over 20 years ago. This predates Cycles/Eevee, but I don't think it's something they'd regress on.
sznio
a stupid-simple approach would be to split up the render betweeen machines by manually starting it on each one and setting different frame ranges to render
diggan
Once you feel like that isn't enough anymore, you can also start dividing each frame into a grid of N cells and distribute that :) As long as the rendering is deterministic, you'd just join the cells into a complete frame on the coordinator.
pier25
Weren't Blender working on a more efficient cycles renderer?
pilaf
You're probably referring to Cycles X [1], which if I'm not mistaken has already been released.
It will never be on-par with Eevee's performance though as they are fundamentally different approaches to rendering: Cycles is a physically-based path-tracing engine, while Eevee uses rasterization through OpenGL.
pier25
You're right.
I think I confused it with the Eevee Next project released last year.
https://code.blender.org/2024/07/eevee-next-generation-in-bl...

I just had a look at the trailer, and I'm trying not to poo on it's parade, but this thing looks... disappointing - worse than most in-game cut-scenes these days. It doesn't even feel "Artistic", and I'm definitely not a snob for "hyper realistic" types of looks.
The distant and "landscape" views look very nice, and in stark contrast to the game-like and amateur rendering of close up scenes with the animals. They don't even have anti-aliasing and the things look "blocky".
I hope this thing won because of the story and characters, and not its visuals.
snowwrestler
There are incredible visuals in the movie, but not because of their realistic details. They are instead incredibly evocative of a mysterious depth behind the relatively small story being told in the movie.
The movie doesn’t look real, but it also doesn’t act real either.
sepositus
With the amount of utter trash that modern Hollywood puts out, combined with the Oscars always feeling like a "pat on the back for rich snobs," I am just genuinely happy to see something like this win anything at all.
Seems like a fluke, though.
billin
I watched Flow in the theater. On the big screen, the less-polished look definitely comes across as an artistic choice, enhancing the otherworldly quality of the world and scenes it depicts. Combined with the great animation of the animals and the audio, you leave the theater in wonder. I suspect the visual roughness becomes more jarring in a less immersive environment.
ChrisMarshallNY
The look is scruffy.
The story is not, and the visuals are sufficient to tell the story.
Funes-
I agree, but mainly for some other reasons I won't be listing just now. As much as I find it all very cute and I'm a sucker for this kind of shit (I can already sense I would cry my heart out watching this at some point or another--I know, I'm very sensitive), it kinda looks like a long-winded tech demo or video placeholder.
raverbashing
Honestly yeah it won't be "perfect" but neither is a videogame being rendered in real time and it looks pretty good
Since they're not going crazy with effects it seems like a good compromise

legitster
I did not find Flow to be a technically impressive movie. The animation was very imperfect. The rendering (especially shadows and textures) were off. The whole movie looked like a video game cut scene.
But oh boy, what an amazing cutscene to watch. I'm worried that the story the media is putting forward is that this was an innovative and cutting edge movie - based only on a superficial appreciation of the (stunning) art design. But the real story is how the director worked within his limitations to make something equally enjoyable and meaningful as the other guys.
Most importantly, this movie passed the Actual Kid (TM) test. My 7 year old and his friends sat raptured through the entire movie without any slapstick, pop music numbers, or even dialogue! Not once, but 4 times now!
brundolf
A takeaway may be that cutting-edge rendering doesn't really matter for cartoon-stylized films, especially for kid viewers
stvltvs
Yep, grew up on cartoons like Transformers, GI Joe, Thundercats, etc. Looking at them now, they are laughably bad in most respects, but they sparked our imaginations and didn't need to be sophisticated to do it.
ChrisMarshallNY
But some of the really old (like 1940s) cartoons were very smooth and well-done. I have DVDs of old Tom & Jerry cartoons, and they are excellent.
My experience, is that the ones made in the 1970s and 1980s had crap quality.
I watched this movie, and think it very much deserved the Oscar, but the character rendering was a bit “scruffy.” The environment rendering was great, and it looks like they optimized for movement, in the characters, which was a good choice. Once I spent some time, watching, the rough rendering didn’t matter.
I had a similar experience, watching Avatar. At first, it seemed like a cartoon, but I quickly became immersed, and the fact it was rendered, didn’t matter.
I read, somewhere, that the movie is being re-rendered. I think they may have the money for that, now.
Hoasi
If the goal is sparking the imagination, these flaws are often a feature, not a bug. You have to do a little bit of work to complete the picture. That's also why the original book is almost always better than the fully rendered movie inspired by the book. No matter the budget.
bombcar
You have things like Homestar Runner that were animated in Flash.
Animation tools are just part of the story-telling tools, and just because something is visually beautiful in stills (or even animated) doesn't mean that the story is well told, or the tools well used.
And often 'bad graphics' or whatever you want to call it can actually help with the story, just like low-def TV, because it covers up things that are unimportant without drawing attention to it.
agumonkey
yes, there's a balance to get and visual "perfection" is nothing real, even star wars had blunders and visibly lesser tricks, but the whole created a deep sense of wonder and you got along
kevinventullo
I think Nintendo figured this out years ago. Their games are not graphically cutting-edge, but they still sell like crazy.
Liquix
nintendo has distilled their own flavor of "disney magic". their flagship games are polished beyond belief, the art direction is a careful choice. they hit the borderlands bullseye over and over - not particularly cutting edge to a gfx professional but unique, cohesive, and beloved.
brundolf
A key there (and it sounds like in the OP) is that art direction is an order of magnitude more important than graphics technology, especially these days
Rendello
A lot of the cartoons I watched as a kid had excellent animation, and a lot was very primitive 3D rendering that looks horrible in comparison. As a kid, I didn't even notice!
crooked-v
I feel like it kind of fits in the same category as Hundreds of Beavers (also a fantastic film), as something using the roughness of low-cost methods as a genuine part of the artistic style.

Recently I reminisced about Blender foundations first(?) effort, Tears of Steel, with the script like "Look, Celia, we have to follow our passions; you have your robotics and I just want to be awesome in space!" - "Why don’t you just admit that you’re freaked out by my robot hand?!"
It's not about the textures and shadows.
seba_dos1
"Tears of Steel" was the fourth Blender Open Movie project. The first one was 2006's "Elephants Dream", then "Big Buck Bunny" and "Sintel".
From the more recent ones I highly recommend "Sprite Fright".
UncleEntity
I don't know what they've been up to after Tears of Steel but the primary mission of the older Blender Foundation movies was to further the tech, e.g. motion tracking.
deskr
The shaky camera is a deal breaker for me. Doesn't matter if it's animated or not, TV series or film. Shaky camera is an instant switch off for me.

That's kind of surprising. Academy members are not required to watch all the nominees for Best Animated Feature before voting. In fact they are not require to watch any of them.
Several years ago I remember that after a year where the movie that won best animated was not the one that those in the animation industry overwhelming thought was sure to win some animation industry magazine survived Academy members asking which movie they voted for and why.
What they found was that a large number of the voters thought of animated movies as just for little kids and hadn't actually watched any of the nominees. They picked their vote by whatever they remembered children in their lives watching.
E.g., if they were parents of young children, they'd vote for whatever movie that their kids kept watching over and over. If they no longer had children at home they would ask grandkids or nieces or nephews "what cartoon did you like last year?" and vote for that.
Another factor was that a lot of these people would vote for the one they had heard the most about.
That gives Disney a big advantage. How the heck did Flow overcome that?
Inside Out 2 had a much wider theatrical release in the US, was widely advertised, made $650 million domestic, is the second highest grossing animated movie of all time so far worldwide, and streams on Disney+.
All that should contribute to making it likely that those large numbers of "vote even though they don't watch animated movies" Academy members would have heard of it.
Flow had a small US theatrical release at the end of the year. I didn't see any advertising for it. I'd expect a lot of Academy members hadn't heard of it.
As a guess, maybe Moana 2 is the movie that the kids are repeat streaming. That was not a nominee so maybe those "vote for what my kid watched" voters didn't vote this year and so we actually got a year where quality non-Disney movies had a chance?
CmdrKrool
Interesting. I loved Flow and I'm glad the stars aligned for it on this particular occasion. This article [1] lists a bunch of other Oscar-related firsts:
* Gints Zilbalodis, who is 30 years old, is the youngest director to win the Oscar for best animated feature.
* Flow is the first fully-European produced and funded film to win the feture animation Oscar.
* Flow is the first dialogue-less film to win the feature animation Oscar.
* Flow, made for under $4 million, is by far the lowest-budget film to ever win the category.
It also says the winner of the animated short category, In the Shadow of the Cypress, was unexpected since the Iranian filmmakers couldn't do any of the usual in-person campaigning of Academy voters due to visa problems.

chillee
A couple things:
1. The academy has had a significant increase of young voters in the past 10 years or so. Generally speaking, young voters are more likely to take animation as a "serious" medium.
2. These interviews were always somewhat overstated. Of course some voters have stupid rationales, but I don't think this dominates the academy.
3. Disney's Inside Out 2 was nowhere close to winning the award this year - Flow's biggest competition was The Wild Robot, which did gross far more than Inside Out 2, but far below Inside Out 2.
If you look at the past couple years, The Boy and the Heron (Studio Ghibli) won over Across the Spider-Verse (with Pixar's movie Elemental nowhere close) in 2023, Guillermo del Toro's Pinocchio won over Across the Spider-Verse (with Pixar's movie Turning Red nowhere close) in 2022, etc.
I'm curious what year you're thinking about above. Perhaps Toy Story 4 over Klaus in 2019?
zimpenfish
> Flow's biggest competition was The Wild Robot, which did gross far more than Inside Out 2, but far below Inside Out 2.
Exactly the same as Inside Out 2 then?
(I'm guessing it was far more than Flow but less than Inside Out 2?)
brookst
4. The results can still be valid if there’s a lot of random noise in the sample. There are about 10,000 voters here. If 9,000 vote at random and 1,000 watch the films and vote on merit, there’s about a 2% chance of getting a different result than if all 10,000 watched and voted on merit.
stuart78
I would guess this is, to some degree, a generational shift. The Animated category has only existed for ~30 years and was born from the resentment many in the academy felt toward Beauty and the Beast being nominated alongside supposedly serious films for Best Picture. Each generation following that one has grown up with a more diverse slate of animated films available.
The Oscars are the slowest possible reflection of social change, and I’m sure the perspective you share is still held my many members, but this win holds out some hope for sure.
dmazzoni
The Grammy awards for music are the same thing. Members aren't required to listen to the nominated albums, and every member gets to vote in every category.
I had a friend who was a Recording Academy member as a classical musician. He thought it was strange that they asked him to vote for the best hip-hop album since he doesn't listen to hip-hop at all.
So for many of the categories that are a little more niche, it basically turns into a popularity contest, rather than the opinion of true experts.
SoftTalker
Reminds me of when Jethro Tull won best Hard Rock/Metal category, beating out Metallica and AC/DC.
tootie
I adored Flow. It's hard to say it was truly "better" than Inside Out 2. I think part of the calculation has to be that everyone expected Pixar to deliver something top notch so it only really met expectations. Flow was made by a no-name team from Latvia and was really something unique and interesting. I went into it kinda blind with no expectations and was blown away.
riffraff
I didn't think inside out 2 was a very good movie.
It had good ideas but didn't do very well with them (contrary to the first movie, which was great). I'm not surprised a movie which wasn't "just a sequel" managed to beat Moana and IO2.
brookst
The title of the movie is perfect. It’s more of the same. Which is still very good, but lacking in anything novel.
autoexec
I was also disappointed by inside out 2. I thought it followed the story beats of the first one a bit too closely. Flow was the better film.
lukasb
Flow was a critical favorite, sometimes that matters at the Oscars.
jfengel
They aren't required to watch them, but the voters do all get screeners. They at least have the opportunity to watch it, regardless of whether they've seen it in the theater. They don't vote just for what they've heard of.
The Academy has a reputation for seeking "artistic merit" even at a cost of good entertainment. They're hoping to advance something that didn't do well at the box office. Sometimes that means giving awards to films that turn out to be dogs, but sometimes they manage to promote things that deserve attention.
A lot of Oscar-bait gets a small release at the end of the year, to qualify it for the Oscars. If it gets a nomination, they'll use that as part of a wider campaign later. That's why they send out screeners: they know that many members won't have had a chance to see it in the theater.
Timwi
Could they have heard of it en masse because of its success at the Golden Globes?
dkh
Historically the Golden Globes are the biggest predictor of the Oscars, so, yes, but then you have to ask how it won the Golden Globe lol
bombcar
I suspect as I said elsewhere that "feature length movie with no dialogue that's actually good" was enough to get people watching it, even seeking it out. We're more than a hundred years out from silent movies, so it's a curiosity by that metric alone.
And then it turns out to be actually good!
It's similar to the Lego Movie in that respect, everyone had assumptions about what it was and then it went and was well done and hit you right in the feels.
lucideng
For me, Flow's greatest strength was the complete lack of voiceovers, almost like a silent film. No overbearing narrator coercing you. Flow allows you to feel on your own terms without interference.
With most media since the dawn of Hollywood, the internet and now AI, we are accustomed to being told exactly what is happening. Think about how 'laugh tracks' tell you to laugh. The search for an answer or meaning of something is largely taken away from you. Without that instruction you are left to make your own interpretation of things, no delivery of a specific message or theme. This means the movie is experienced differently by everyone. That why it's so great.
fosterbuster
Almost reminiscentof Hitchcock only using intertitles sparingly, instead letting the images convey the story.
viccis
As someone who started using Blender before 1.8, posting on the old blender.nl forums before its move to BA, it's just been pretty insane to watch it reach this point. Back then it didn't even have ray tracing, and all of the attempts to make long form videos with it were very very rudimentary.
owenpalmer
I remember being a little kid learning Blender, rooting for it to become the industry standard. It's amazing to see how much the project has grown.
kylecazar
I heard him thank Blender in the first few sentences and had to Google it to see if he was talking about THAT Blender!
I remember doing all the tutorials when I was younger and considering game dev.
bombcar
"I would like to thank Blender, and Flexo, and Fry."
maxglute
It shows, Blender has come a long way, but FLOW doesn't look technically incredible. On the otherhand, I just rewatched Shrek recently, and complex graphics isn't everything.
raxxorraxor
What do people mean with technically impressive? There are Blender renders that look quite incredible though and you just cannot differentiate it from real picture anymore
Example: https://images.squarespace-cdn.com/content/v1/58586fa5ebbd1a...
There are probably some flaws here as well, but you need to study the picture in detail. And Flow used the fast renderer of Blender, not the quality one.
Still, it does have a unique style that is much more interesting than many other animated movies. So what is technically impressive, just throwing more compute at it to make it photorealistic?
I think art style will have a larger impact. In a way it is technically impressive as it didn't need a lot of compute power.
WhatThisGuySaid
I think people are specifically referring to the movie not looking technically impressive, not that Blender isn't capable of technically impressive renders at all.
null
raverbashing
No kidding, Shrek probably had to do with 100x less computing (per hour) than a modern production. First Toy Story probably something like 1000x less computing
We did come a long way
pbronez
Great example of how accumulated technical innovations unlock unexpected opportunities. Flow, Shrek and Toy Story have roughly similar technical quality but vastly different price tags. That cost reduction allows more experimentation, which delivers more compelling outcomes.
bombcar
It's kind of surprising to go back and watch Toy Story in 4k today - the rendering really is quite rudimentary compared to what even video games put out now.
But - you have to be paying attention to see it, because Pixar knew the limitation of their systems. For example, rendering of the time made everything look plasticy, so they rendered ... plastic toys as the main characters! The most noticeable graphical issues are with the rendering of people, but those are put in the background.
Clamchop
Blender comes with two renderers: Cycles for production rendering, and Eevee for near-real time preview.
This movie was rendered with the latter.
Like any 3D package, you can also install other renderers.
So any perceived deficit in picture quality here is more to do with budget than some limitation of Blender.
maxglute
Yeah, the real time stuff is pretty solid in blender but for very high image quality / realistic prerendering, blender is still missing a lot of the professional/proprietaries tools that gives the last 10% of polish in big budget productions (photorealism). The community has done a great job in last 10 years but there's still a lot of technical tools locked behind something like max/maya ecosystems professional paywall that most people eventually transitions to for "serious" industry work because pipelines are hard to change. At least that's the state a few years ago.
bolognafairy
Take a look at the earlier concepts / renderings for Shrek! Before the studio gutted the team(?) and told everyone to pull their heads in. Absolutely off-putting.
j3s
there are parts of Flow that definitely look incredible imo

Also thanks to Ton Roosendaal. Creating the Blender Foundation and starting the "Free Blender"-campaign with the hopes of getting Blender to where it is now is something I was doubting if it would ever work out. And it did. Blender is one of those gems in the OSS ecosystem.
neoecos
This is the first movie I took my 3 yo kids to watch in a theater. My wife and I are FOSS enthusiasts.
FpUser
I could not give a flying fuck what it was rendered with , tech level is not impressive. But what a story and presentation. I find Flow beautiful. I, my daughter and my grandson watched it and could not take our eyes away from it.
dkh
You may not care, and you don't have to, but certainly it means a lot to the Blender Foundation, who for 23 years have been actively working on something free & open-source, and now finally it is in the big leagues.
Just as Flow's win looks even more impressive when you look at the films it competed against, who produced them, and what resources they had, Blender has been a project competing for parity and to be taken seriously while remaining totally free, and going up against systems that are either wildly expensive or not available outside the studio that made it at all.
Flow is not good because it was made with Blender, but Blender is proven to be very good and in that top echelon because Flow was made with it. For those who make or use Blender, this is big. Those folks have already believed for years/decades that Blender was great and serious, but now a lot more people outside that circle will know this, too.
FpUser
Look, I am in no way trying to diminish work developers put in Blender. It is great product. I saw videos made in Blender that looks way better than Flow from the tech point of view.
My point was that the value of Flow is in its story, both written and visual and far overshadows any technical aspect. Avatar for example is totally opposite from that point of view in my opinion. Great graphics and absolutely meh, story.
null
elaus
And the value of Blender (or any 3D rendering software) is not only the fidelity of the rendered result, but the tools it gives artists to transform their vision into something that can be rendered by a computer.
PaulDavisThe1st
The point is that this amazing story could be produced, as a finished movie, by a team that only needed to raise about $3M. Precisely how much of that is because they used Blender is still not clear to me, but the importance of Blender's use here is that it opens the door to equivalently great (or even better!) story telling on (relatively) low budgets ($3M is still a lot to raise, it seems to me). This story would never have been made if it needed $30M or $300M to make.
autoexec
> I could not give a flying fuck what it was rendered with , tech level is not impressive.
It's pretty impressive to me that something of Flow's quality could be created with free software that's avilable to anyone with an internet connection. There are a lot of highly creative people out in the world without massive amounts of money for expensive hardware/software. It's exciting for the future of animation, and I hope all the news stories talking about Flow being made with Blender will inspire more people to give it a try and see what they can do with it.
Not only was it made with Blender, the final renders were done with Blenders semi-realtime Eevee engine rather than its max-fidelity Cycles engine. That reduced the compute required by orders of magnitude - the director said a render farm wasn't necessary because his local workstation could produce final-quality 4K frames in 0.5-10 seconds.
"Proper" production renderers like Cycles do look better of course, but having an alternative which is viable on a shoestring budget is very valuable.
