here we go guys battle stations right now to the couch we got a vfx emergency get up here get up here all right welcome back to vfx

we're having an emergency session right now because you guys know we're about to watch it's just very strange it's just very strange it's like technically it's actually totally fine it's just very strange but we're not here to like dig into the critiques of cats the broadway musicals gandolf the cat gandalf the gray cat now gained off the white cat that shot hey just kind of trying to get some cheese wait so some cats are wearing jackets but other cats aren't wearing anything and i can't tell is judy dench's jacket her fur or is it a jacket is it dead cat fur dead cat is it a dead cat where'd they get the first that is an interesting question though so i think it's important to note that almost no one really knows much about this movie so most of what we're saying here is pure speculation according to the actors who are on set they actually had costumes and the only thing that they're going to be adding were like 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 are seeing right now are actually unfinished they're at like the 80 to 90 finish stage and honestly some of these shots look really good from a purely technical standpoint the vfx are totally a-okay none of the

ions here are oh...

the lighting sucks so this looks so fake and cg like it looks cg but like it doesn't look like they made a mistake in how it looks everybody's actually

ing to what they should be

ing to which is the decision to make human animal hybrids they have human animal hybrids why are we debating whether the earth is flat dude they have human animal hybrids it's like the character itself is freaking people out not the technical achievement of it like sonic it was the character itself that was a little weird looking uh meow they don't look right and a lot of people have been attributing this to the uncanny valley i'm getting some uncanny valley for sure all of their faces are covered in fur yeah the entirety of their cheekbones and cheeks it's all covered in fur and yet it still retains a very human face like quality judi dench for instance it looks like an actual photography plate of her face on a cg cat cause it almost looks like they like cut out like the eyes and the nose and the mouth i think that's what's throwing me yeah and they're being stuck back onto the model it definitely yeah it definitely feels that way it's it's well integrated and they're doing a fine job of it but like that definitely lends itself to a bit of this strange

ion everybody's having because you're getting just very raw like pieces of human cut out and stuck under this character the weirdness always comes down to the face but also the way...

she was running up to that gate apparently they all had to go to what's called like cat school where they learn how to act like cats i'm not kidding so part of part of the weirdness comes from their walking is not like a normal walk they're all like humans acting like cats that's why i just think the whole movie is weird i just like i can't i'm not gonna say anything this is a very weird movie i am not disagreeing with you there tom's pairing them with a kind of level of technology which i don't think has ever been used before so what i'm gathering here is the jackets are real the faces are kind of real and then the body and that kind of stuff has basically been replaced by a fur and a cg body we've used digital fur technology to create the most perfect covering of fur they did wear the costume and they did all the choreography for real and i think taylor swift even said there was no motion capture which means they're basically matching an actual animation of a cg person to the real performances on set okay that's a that's a big door it's a big door that's a big door so the sets are real from gathering this i assumed the sets would be real because just like the actual play they built like oversized sets to make everybody feel small they all have these headbands oh yeah look at that there's a person in the background wearing motion tracking markers so they definitely are having a bunch of tracking markers on them...
vfx artists react to bad great cgi 7
so that is absolutely a form of motion capture if we get a glimpse of his monitor there you can kind of see so somebody is wearing a suit but i bet you that's just for lighting reference that's motion capture yeah that's motion capture all right well it's definitely apparent they're using a variety of methods to capture the motion of the choreography you know we're seeing motion trackers but these days you need what we've been doing with our accent suits uh you guys can actually check out this project we did sam built a video game we can control it with a motion capture suit it was the previous video to this one so check it out if you haven't seen it yet because it showcases a really interesting piece of technology which also kind of calls into question why they wouldn't just have actors wear one of those if they're going to replace them anyways these are people but they're cats and this is kind of blowing my mind they've erased the person a hundred percent now and it's a complete cg character it's just straight up it's a weird monster you're watching weird monsters dancing around on the screen i feel like it'd be more valuable to have people in costumes that there's still the person there yeah all the

ions 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 umbrella art...
direction is certainly part of it this this trailer is like glass blowing art like what who who nobody asked for this that's the thing 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 the same thing for two hours hey you know what if you want to go see that movie good for you i'll probably check it out you'd also like glass blowing what is that glass blowing who wants this oblong marble who wants this thin marble like i don't want that what is what's this like croissant doughnut thing let's jump into our patron decided scene we do a scene where our patrons get to vote and this is the winner you know it's kind of crazy to think that like there was all this hubbub about 2012 in the end of the world that was so long ago that like i totally forgot about it this looks so good really good role in denmark right the same guy that did independence day he's the master of world ending stuff look how good that looks look at all the plants moving all the physics on all that there's so many problems one tree is like enough to crash my computer the crazy thing here is like bring all of it together it's nuts hold on to those legs how much of this do you think is actually practical except for the mud i think this is 100 computer generated that is correct this is a full animation and they did this back in 2009 watch out john cusack the...
building's collapsing though there i've never seen a building collapse up this way i've never seen a building collapse look as good as it did in this because i don't think any movies got that structural slow everything falling apart vibe oh that's a good one look at those trees is that the same is that the same golf course harrison ford crashed in it is oh in real life he crashed there yeah not for a movie yeah oh wow holy crap look at that dude that is cool what whoever wrote this scene was like the airplane flies over us the city falls underneath it look at all that dude look at all this that's so much physics objects like just having that many objects is hard for a computer let alone physically simulating all of it on top of like the smoke and the dust and the plants waving in the wind oh the train i love the train coming out flying under it i mean they could pull up by this point but that wouldn't be any fun look at the water man what a what a sequence all of this stuff going on is simulated the the building's collapsing the street and road coming up the grass caving into itself it's not like a person going in and moving every single brick right they know that they want a bridge to collapse right it's like a hit play and let it simulate and then you let the physics do its job but a person has to animate in all these events to start and stop at certain points essentially they're doing like the macro view the the amount of...
computing power to do this shot alone like i can't even comprehend there's a lot of technology that you now see in every film that was kind of this film was kind of the first one to do it so this shot right here blows my mind obviously you have a bunch of physics and stuff going on the reason this blows my mind is because it's bringing everything together in the visual effects world at that time at the height of its full potential into one shot you're seeing a bunch of different software and a bunch of different programs being brought together for a single shot and likely a bunch of things being rendered out in different places and that mastery of bringing all these things together is where roles like a visual effects supervisor comes in handy because you need that that director that coordinator to make all this software talk to each other and make sure all these pieces line up like just a plant alone with leaves looking realistic and moving in the wind is hard for a computer to do there are hundreds of palm trees hundreds of plants in the shot there are yards with grass a house collapsing is hard to do there are like 20 houses collapsing in this shot not to mention the street falling apart the cars falling into it the dust the smoke all that stuff it's just it's a masterwork of things coming together i think it'd be really cool to talk a little bit about how you actually achieve some of these physics and how like you could even achieve some of...
these physics now the physics engine they use in this movie is called bullet physics that's doesn't mean it's physics for bullets it's that'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 a kind of internal friction so what i mean by that is let's say you have a stack of blocks wooden blocks now the wooden block on the bottom of that stack is under the weight of that full stack meaning it's going to have more friction because it's under all that pressure you need this internal friction to have large structures collapse accordingly because large structures have weight and pressure inside of them so this is a

great

demonstration of bullet physics this is this is effectively exactly what's happening in 2012 except those little wooden blocks are being replaced with like concrete and glass right there you see how it didn't collapse because the internal pressure and internal friction of the blocks sitting on top of each other is keeping the blocks on the inside from being affected that's something that only bullet physics could do back in the day so this here is physics and notice that when the ball goes to the top the bottom immediately kicks out of this tower and that's because you're not getting an eternal friction that bullet physics is giving the moment one object in that tower...
gets motion that motion translates to everything and suddenly the bottom blows out and the whole thing falls over and it's not stable if your physics simulation isn't accurate we can still pick up on the false motion but here the motion is very true to real life and it looks very real we looked at 2012 and that was because you guys chose it on patreon so thank you for voting there and you can become a patron and vote for the next one too link in the description below ooh jonathan wick johnny wick jonathan wiggle i think they're gonna try to hurt john wick but john wick don't take no guff who's that can't tell who it is there's a shadow on his face could it be the same guy who was to get in the shower oh it is black bad guy pretty smart john wick he's a little bit smarter a little bit smarter but also let's just like not discount that keanu's heart rate is probably not exceeding 80 to 82 in fact it goes down kyano reeves lowest resting heart rate is when he's fighting because that's when he's the most relaxed dead dead everybody's dead so you might wonder what we're

react

ing to in the shot the muzzle flashes it's a cool movie and i love these fight scenes but the muzzle flashes they're just a little disappointing in motion they look fine i actually think in motion they could look even better there's one thing that we're particularly good at here at corridor it's muzzle flashes muzzle flashes...
we've been doing for like 20 years a long time perfecting our muzzle flashes because there's certain physics with how muzzle flashes work and they don't quite adhere to it for john wick so these aren't real guns obviously you're not going to shoot wheel guns but blank firing guns are frequently used in productions we actually got to use blank firing guns for our battlefield series blank firing guns are deadly they are basically real guns if remember brandon lee from the crow he was killed by a blank firing gun actually multiple people have been killed by blank firing guns on set you're not going to be able to use blank firing guns in a situation like this it's just it's too dangerous they're probably using airsoft guns gas powered airsoft guns so some things that you immediately notice is you have the muzzle flash that muzzle flash puts light into the scene and muzzle flashers are actually pretty bright the light's not bad they're adding more light to the scene basically just painting it in by hand you can see it on the front of kiana reeves you can see in front of that stunt man the blood's looking a little weird but it's just for one frame so it's usually not that big of a deal but there's an immediate flaw that stands out to me muzzle flashes don't exist for two frames they also especially do not go backwards into the gun you shoot the gun the gun powder in the shell expands the gunpowder turns basically into...
expanding gas in the initial stage that gas is glowing and that's the flash that's the fire so you'll sometimes capture no muzzle flash sometimes you'll capture the tail end of a muzzle flash in fact it depends entirely on your camera most cameras these days have rolling shutters which means that it's scanning from top to bottom and a truly real muzzle flash is sometimes only captured halfway so this is a real m249 shooting real blanks all right so that's a real muzzle flash notice how bright it is in the scene around it it generally did a good job of that with john wick it's brightening his face there's a reflection in his goggles it's also huge also notice that we're only capturing the top half of it the star is not coming out the bottom because of the rolling shutter now notice on the ground below it it's kicking up dust on the ground that's an actual shock wave from the front of the gun and that's not a fake camera shake that's us going ah you're shooting the gun the next issue is the smoke there's no smoke you wanna know how to give a gun power you show the power with the ejecting gases you show it with the smoke the smoke is just the cooled gases that the muzzle flash was made out of so if those hot gases in one frame expanded to this big and then the next frame now that's just smoke and they're the same size that makes zero sense for the physics of the scene now notice the smoke coming out of this...
gun is as big as the muzzle flash the general rule of thumb is if in one frame you've 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 the next frame the gases should be this big the size of the smoke coming out of these guns should be leaps and bounds bigger than what you're seeing in these shots and that expansion of the smoke and that fast puff that comes out of the gun gives that impression of that punch and of that projectile just rocketing out of that gun at like mach 1 and they don't have that in john wick here once you drop in the smoke at the right scale at the right speed suddenly your gun seems powerful but you know what i would like to see what john wick would look like with actual realistic muzzle flashes and i think we could fix the muzzle flashes in john wick so if you guys remember how he fixed the scorpion king i would love to try fixing the muzzle flashes and john wick so if you'd like to see us try fixing the muzzle flashes from john wick and a couple other movies too subscribe to the channel it's gonna be coming real soon i like john wick a lot i'd love to see it accurate to real guns if you've seen any movies or tv shows that you want us to remember tv shoes yeah that's what i said if you've seen any tv shows and god dang it if you've seen any movies or tv shows with visual effects that you want us to look at leave a...
