we're having an emergency session right now because you know we're about to see it just very strange it's just very weird it's like technically it's actually totally fine it's just really weird but we're not here to delve into reviews of cats the broadway musicals gandolf the cat gandalf the gray cat now beat the white cat who shot Hey, I'm just trying to get some cheese, wait, so some cats wear jackets, but other cats don't wear anything and I can't tell if Judy Dench's jacket is her fur or it's a jacket.

Is it dead cat skin? Dead cat, right? a dead cat, where did they get the first one? It's an interesting question though, so I think it's important to note that almost no one knows much about this movie, so most of what we're saying here is pure speculation based on the actors who are on set, they actually had costumes and the only thing they were going to add were whiskers, tails and ears, so one person's job is just the tail lord, just adding tails to everyone, so most of the effects we're watching right now they are actually unfinished, they are in the final 80 to 90 stage and honestly some of these shots look

great

from a purely technical point of view, the visual effects are totally fine, none of the

ions here it's oh the lighting sucks so this looks so fake and cg looks cg but it doesn't look like they made a mistake in their appearance, everyone is reacting to what they should be reacting to which is the decision to make human animal hybrids.

They have human-animal hybrids. Why are we debating yes? the earth is flat dude, they have human animal hybrids, it's like the character itself is scaring people, not the technical achievement like sonic, it was the character itself that was kinda weird looking, uh meow, no They look good and many people have been attributing this to the uncanny valley. I'm getting an uncanny valley, sure all their faces are covered in hair. Yes, the entirety of his cheekbones and cheeks are all covered in hair and yet he still retains a very human facial quality. Judi Dench, for example, looks like a real photograph of her face on a computer-generated cat because they almost seem to like them cropped out, like the eyes, nose, and mouth.

I think that's what baffles me, yeah, and they're getting stuck. on the model, definitely yes, it definitely feels like that, it's well integrated and they're doing a good job, but like that it definitely lends itself to a little bit of a weird reaction that everyone has because you're getting very raw pieces. from human cut off and trapped underneath this character, the weirdness always comes down to the face, but also the way she ran towards that door, apparently everyone had to go to what's called a cat school, where they learn to act like cats. I'm not kidding so part of the weirdness comes from the way they walk isn't like a normal walk, they're all like humans acting like cats, that's why I think the whole movie is weird, I just like it, I can't, I'm not.

I'll say anything. This is a very strange movie. I don't disagree with you. Tom is combining them with a kind of level of technology that I don't think has been used before. So what I'm gathering here is that the jackets are real. the faces are kind of real and then the body and that kind of stuff has basically been replaced by cg fur and a cg body. We have used digital fur technology to create the most perfect fur coverage. They wore the costume and did all real choreography and I think Taylor Swift even said there was no motion capture, which means they're basically matching a real CG animation of a person with the actual performances on set, okay, that's a big door, that's a big door, that's a big door.

So when putting this together, the sets are real, I assumed the sets would be real because like the real play, they built like oversized sets so everyone felt small, everyone has these headbands, oh yeah, look what's there a person in the background using motion tracking. markers, so they definitely have a lot of tracking markers, so it's absolutely a form of motion capture. If we take a look at their monitor there, you can see that someone is wearing a suit, but I bet you it's just for lighting. reference, that's motion capture, yes that's motion capture, well it's definitely evident that they are using a variety of methods to capture the movement of the choreography.

You know, we're looking at motion trackers, but these days you need what we've been doing with our accent suits uh, you guys can see this project that we did. Sam created a video game that we can control with a motion capture suit. It was the video before this one so check it out if you haven't seen it yet because it shows a really cool piece of technology that also questions why they wouldn't make the actors wear one of those if they're going to replace them anyway, they're people but They are cats and this leaves me speechless. they've erased the person one hundred percent now and he's a completely CG character, he's simple, he's a weird monster.

You are watching strange monsters dancing on the screen. I feel like it would be more valuable to have people in costumes than the person is still there, yes all the reactions here have nothing to do with the technical execution, this isn't about the visual effects, it's about the art direction, but that's part of the overall visual effects, the overall art direction is certainly part of this, this trailer. it's like glass blowing art like what who who nobody asked for this that's what it's the worst musical of all time it's not a very good musical that's for sure we're cats for wonky here's a song about a cat and then it's what same for two hours hey, you know what?

If you want to go see that movie, good for you, I'll probably watch it. You might also like to blow glass. What is that blown glass? Who wants this oblong marble? Who wants this skinny marble like me? I don't want that, what is this croissant donut thing? Let's jump to the scene decided by our clients. We make a scene where our customers can vote and this is the winner. You know, it's a little crazy to think there was all this fuss. 2012 at the end of the world which was so long ago that as if I had completely forgotten about it this looks very good, very good role in Denmark, right, the same guy who did independence day, he is the master of things of the end of the world, look how good it looks, look at all the plants moving all the physics in all of that there are so many problems one tree is enough to crash my computer the crazy thing here is how to put it all together it's crazy grab those legs how much of this do you think what is it really? practical except for the mud, I think this is 100% computer generated, that's right, this is a full animation and they made it in 2009, watch out John Cusack, the building is collapsing, although I've never seen a building collapse from this way.

I've never seen a building collapse as well as this because I don't think any movie has that slow structural feeling of everything falling apart oh that's a good one look at those trees and it's the same as the Harrison Ford golf course itself . crashed there oh in real life crashed there yeah not for a movie yeah oh wow look at that guy that's cool whoever wrote this scene it was like the plane was flying over us , the city falls below, look at all that guy. look at all this there are so many physics objects just having so many objects is hard for a computer let alone physically simulate everything on top of it like smoke and dust and plants waving in the wind oh the train I love it the train. flying out from under him, I mean they could stop at this point but that wouldn't be fun, look at the water man, what a sequence, this whole thing happening is simulated, the building collapses, the street and road comes closer. the grass sinks in on itself, it's not like a person comes in and moves each brick, they know they want a bridge to collapse, it's like a successful play and you let it simulate and then you let physics do its job, but a person it has to animate all these events to start and stop at certain points essentially they do it like the macro view the amount of computing power to do this shot just like I can't even comprehend there's a lot of technology that you now see in every movie that was kind of of film was the first to do it, so this shot here blows my mind, obviously you have a lot of physics and stuff, the reason this surprises me is because it brings everything in the world of visual effects into that moment, at the height of its full potential, in a single shot, you're looking at a bunch of different software and a bunch of different programs brought together for a single shot and probably a bunch of things rendered in different places. and that mastery of putting all of these things together is where roles like visual effects supervisor come in handy because you need that director, that coordinator to make all of this software talk to each other and make sure that all of these pieces line up as a simple plant. with leaves that look realistic and move with the wind it is difficult for a computer to do there are hundreds of palm trees hundreds of plants in the shot there are yards with grass a house that collapses it is difficult to do there are like 20 houses that collapse in this Take not to mention the crumbling street, the cars falling into it, the dust, the smoke, all that stuff, it's just a masterpiece of things coming together, I think it would be cool to talk a little bit about how some of it is achieved. of these physics and how could you achieve some of this physics now?

The physics engine they use in this movie is called bullet physics. That doesn't mean it's bullet physics. It's just the name of the physics engine. Bullet Physics is actually an open source physics engine. and one of the things that bullet physics does that other physics engines didn't do at the time was some sort of internal friction, so what I mean by this is let's say you have a stack of blocks, wooden blocks, now the wooden block at the bottom. of that stack is under the weight of that entire stack, which means it will have more friction because it's under all that pressure.

You need this internal friction for large structures to collapse accordingly because large structures have weight and pressure inside them, so this is a

great

demonstration of bullet physics, this is exactly what is happening in 2012, except that those little blocks of wood are being replaced by concrete and glass. There you see how it did not collapse due to the internal pressure and internal friction of the blocks on top. one of the other is to prevent the blocks inside from being affected, that is something that only bullet physics could do in the past, so this here is physics and notice that when the ball reaches the top, the bottom immediately shoots out of this tower and that's because you don't get the eternal friction that bullet physics gives the moment an object in that tower moves, that movement translates to everything and suddenly the bottom explodes and everything falls down and it's not stable if your physics simulation is not like that.

It's not exact, we can still detect the fake movement, but here the movement is very true to life and looks very real. We looked at the year 2012 and that was because you guys chose it on Patreon, so thank you for voting there and you can convert. a sponsor and vote for the next one also link in the description below ooh jonathan wick johnny wick jonathan wiggle i think they are going to try to hurt john wick but john wick don't take any nonsense who is that i can't tell who it is there is a shadow on his cara could be the same guy who was going to get in the shower oh he's a pretty smart black bad boy john wick is a little smarter a little smarter but also let's not rule out that keanu's heart rate is probably not exceeding 80 a 82, in fact, low, Kyano Reeves' lowest resting heart rate is when he's fighting, because that's when he's most relaxed. dead dead everyone is dead so you might be wondering what we are reacting to in the shot the muzzle flashes it's a great movie and I love these fight scenes but the flashes are a little disappointing in motion they look good In fact I think they could look even better in motion.

There's one thing we're particularly good at here at the racer and it's flashes. muzzle flashes we've been making for 20 years, a long time, perfecting our muzzle flashes because there's some physics to how muzzle flashes work and they don't quite stick to it for john wick, so these are not real weapons Obviously, we're not going to shoot blank guns, but blank guns are frequently used in productions, in fact, we have to use blank guns for our battlefield series. Blank guns are deadly, they are basically real weapons, yesDo you remember Brandon Lee from the Raven, they killed him with a blank bullet. shoot a gun in fact, several people have been killed by blank weapons on set, you won't be able to use blank weapons in a situation like this, it's just too dangerous, they are probably using airsoft guns, gas airsoft guns, so some What you notice right away is that you have the muzzle flash, that muzzle flash puts light into the scene and the muzzle lights are quite bright, the light is not bad, they are adding more light to the scene.

Basically, just painting it by hand, you can see it in front of Kiana Reeves, you can see in front of that stuntman, the blood looks a little weird, but it's just for one painting, so it's usually not a big deal, but there is an immediate flaw what catches my attention the flashes do not exist for two frames, they also do not recoil in the gun, you fire the gun, the gunpowder in the shell expands, the gunpowder basically becomes expanding gas in the initial stage that gas is glowing and that It's the flash that is the fire, so sometimes you won't capture any muzzle flash, sometimes you will capture the tail of a muzzle flash, in fact it depends entirely on your camera, most cameras these days have shutters rolling, which means it is scanning. top to bottom and a truly real muzzle flash is sometimes only captured halfway so this is a real m249 shooting real blanks so it is a real muzzle flash.

Notice how bright it is in the scene around you. Overall, he did a good job. with john wick it's lighting his face there's a reflection in his glasses it's also huge also notice we're only capturing the top half the star doesn't come out from the bottom because of the roller blind now notice on the ground beneath it kicking up dust on the ground that it's a real shockwave from the front of the gun and that's not fake camera movement, that's us, ah, you're firing the gun, the next problem is the smoke, there's no smoke, you want to know how to give a power of the gun, you show the power with the expelled gases, you show it with the smoke, the smoke is just the cooled gases that the muzzle flash was made of, so if those hot gases in one frame expanded to this size and then in the next frame, that's just smoke and they're the same size, which doesn't make any sense for the physics of the scene.

Now notice that the smoke coming out of this weapon is as large as the muzzle flash. The general rule is that if in one frame you have gone from here to here, how far should you go in the next frame from the same distance from here to here? So if your muzzle flash is this big and in the next frame the gases should be this big, the size of the smoke coming out of these weapons should be Jumps and leaps bigger than what you're seeing in these shots and that expansion of the smoke and that quick puff coming out of the gun gives the impression of that hit and that projectile just shooting out of that gun at mach 1 and they don't have that here at john wick, once you throw the smoke at the right scale and at the right speed, suddenly your gun looks powerful, but you know what i would like to see what john wick would look like with realistic muzzle flashes and i think we could fix john wick's muzzle flashes, so if you remember how he fixed the scorpion king, I would love to try to fix the flashes and John Wick, so if you want to see us, try to fix John's flashes. wick and a couple more movies also subscribe to the channel, it will be coming very soon.

I really like John Wick. I'd love to see it true to real weapons if you've seen any movies or TV shows you want us to remember. tv shoes yeah that's what I said, if you've seen any tv shows and damn if you've seen any movies or tv shows with visual effects that you want us to watch leave a comment below who knows it might come to that in the next
