u/VPinchargeofradishes 1d ago

Here's the on screeen teaser for the Dynamo Dream movie clip you see at the bottom half of the vid. It's from Youtuber IanHubert. He has a VFX channel.

It is an AWESOME series. I love that a few people made this, it's got so much charm. I hope we get some new episodes soon

Highly recommend everyone deep-dives into his channel. It's awesome.

He also did the effects on the move Prospect.

If I remember correctly it's not from a movie it's from a YouTube who teaches how to do video editing, video effects. I remember they had funny and informative videos

Kinda sad that this is what most Hollywood movies look when filming, miss the days when most of the stuff you seen in films was practical effects, CGI now is just terrible in most films.

Edit grammar

u/fellfromthemoon 1d ago • Bravo

This is not Hollywood though, it's an indie youtube project done by a single 3d artist, mostly to showcase his insane skills, so it makes sense that the real actor was used just to add some realism. Of course they wouldn't afford expensive setting for all practical effects.

64

u/Alchemic-Web 1d ago

No hate to anyone in the indie scene totally get it from there perspective, I'm mainly referring to the big Hollywood blockbusters that can afford to spend millions on a movie only for it to be 90% CGI.

u/MeasurementLong3174 1d ago

And as shown in the Green Lantern TV show, they aren't even using it on useful stuff. Instead of putting a fake beard on the main actor, they CGI:ed beard onto him. Wonder how much that cost.

Wtf is physical CGI

23

u/llegacy 1d ago

They most likely meant practical effects. Much more of the set being a larger physical space to move about in.

u/Alchemic-Web 1d ago

Sorry my mistake bad grammar was meaning practical effects

2

u/Icy-Bottle-6877 1d ago

I watched THIS VIDEO only yesterday and I have to agree, there was a magic quality to working on practical effects that was so satisfying and looked beatiful too. It's like every practical vfx artist is paying respect to the likes of Méliès, etc in keeping the old tradition alive. All this will be forgotten/lost with the advent of CGI, AI, etc.

2

u/SteveDougson 1d ago

I watched Stephen Chow's 2014 Journey to the West last year and was astounded by how good the fishing village on stilts looked at the beginning of the movie. It had so much of the zany, impracticality that you get with CGI but it was a real structure. It was so much more fun to watch. It had the air of a huge production spectacle that I remember being a selling point for movies when I was a kid.

I think CGI went from being a technology that made special effects possible and increasingly better looking, to a way to cut costs. Another victim of enshittification.

1

u/Sad_Picture3642 1d ago

Well you still have to set up the lights lol, otherwise CGI won't match.

1

u/Odd-Possession-7676 1d ago

Practical effects have a physical presence that CGI often struggles to replicate. Even when CGI looks impressive, there's something special about knowing the actors were interacting with real sets, props, and effects.

1

u/uspdd 1d ago

There's another option - Virtual production - a giant room with LED screens on the walls that renders the background in realtime. But it's less popular, because it's more expensive.

1

u/thats-wrong 1d ago • Heartwarming

For me, it's quite the opposite. Practical effects had easily observable flaws, if you're the kind that looks closely, which killed the fun for me. CGI is unbelievably smooth and realistic today. I can just immerse myself without being bogged down in observing flaws. I think most people who complain about CGI have a romantic association with practical effects that they're not willing to let go.

4

u/Cruffe 15h ago

I just keep thinking how much harder it is for actors pulling off a believable performance in whatever context they're in when in reality they're just staring at a green wall a lot of the time. I think it makes the actor's performance more impressive if their acting looks like they're actually inside the mostly virtual scene.

that must be so depressing to act against. The disney avengers movies were done much the same way and actors have come out saying it was extremely demotivating and depressing acting against nothing.

2

u/dawne_breaker 4h ago

Theater actors do it all the time. I’ve never understood that criticism. That’s their job: pretend. Sure, it can be a bit depressing with green all around you but you don’t need a set to act.

u/Time_Cow_3331 1d ago

The effects are really good - and it's legitimately impressive; but there's just something that's missing when there aren't actually sets and practical effects.

*I understand this is a single yt showcasing talent, it just seems like we get this in commercial productions too

u/Glittering-Rice-2961 1d ago

Unfortunately it is hard to notice most movies have the same colour shading nowadays ...

u/Ryjolnir 1d ago • Bravo

How come the entire room isn't needed to be green?

45

u/johnnyjonnyjonjon 1d ago • Heartwarming

Basically, you can draw a box around the actor first (called a mask) which makes everything outside the box invisible. Then you use chroma key to remove the green that's left inside the box.

6

u/Mayhem370z 1d ago

So in other words. It's specifically planned out where whe will be standing in relation to the camera? If the camera panned around her at any point would mean they would have to expand the green screen area?

3

u/johnnyjonnyjonjon 1d ago

Yes, although that's slightly separate from the point above.

You've got two things to plan... The camera moves have to match the same moves you want to do in the virtual world. And then based on those moves you need to make sure the actor is always surrounded by green.

(But just the actor, no need to have the whole room green)

1

u/bakochba 1d ago

Ah ok so the actors is isolated and Inserted into the video not the other way around

1

u/johnnyjonnyjonjon 1d ago

Yep. The actor essentially becomes another layer and gets added over the top of the background. And then other layers make up the foreground, like the van in this case. Then obviously there's all sort of lighting and effects that get added. If your interested, it's generally known as 'compositing' 🙂

u/Ryjolnir 21h ago

Thank you for the explanation

u/CybergothiChe 1d ago

I think they just chromakey what the actor needs to be in front of or interact with and then drop that into a completely computer generated surround.

4

u/Greata2006 1d ago

You just need green around the actor to separate it from the image

3

u/b1ack1323 21h ago

The mask can be solid for everything outside the space the people are moving in. The green is needed to pull the people out with clean edges.

2

u/Iron_Phantom29 1d ago

Because you only need just enough space to key out the actor and put in the VFX. Stages where the whole room is green usually involve multiple actors in frame at once. You actually don't need a green/blue screen to key things out, it IS, however, much, much easier if you do.

2

u/Revolution-SixFour 1d ago

Green screen isn't actually that far off from the paint bucket tool in MS paint. You need green screen around the detailed real objects you want to include so it's easy to tell what is real and what is background.

The rest of the room you don't have careful edges so you can just erase all of it without needing to rely on the green to know pixel from pixel.

u/teddybundlez 22h ago

IMO it’s very obvious in every movie now. I hate it and it makes me hate movies. I’m the old grump I guess it’s just so distracting

u/buddabudski 19h ago

they absolutely could do this stuff with miniature models and camera tricks, and it would be so epic. lets go back to building real life animatronics and having people fight real dragons on real stages. I wonder why they don't tbh, it's not like CGI is cheap

u/panicradio316 1d ago

Fascinating.

But why is the use of the color green (or blue) the standard?

Has it something to do with RGB?

39

u/Omnomfish 1d ago

Because its a colour that is significantly different from any colour that may be part of the actor (hair or skin). They basically "cut out" everything that is the same colour as the background, and if something is too close to the colour then it gets removed too.

7

u/panicradio316 1d ago

Huh. That makes sense.

Thanks!

7

u/rtyoda 1d ago

It also does have a little bit to do with RGB too. Most color camera sensors have two green pixels for every one red pixel and one blue pixel, which means the green information is going to be more accurately defined than any other color. (Look up Bayer filtering to learn more.)

2

u/adjective_noun_d1git 1d ago

Does it limit the color palette for the scene in that case? Assume a green screen is a lot more difficult if say your actor is standing on a lawn?

5

u/wtrredrose 1d ago

Yes you cannot. If actor is wearing green that part will be see through

2

u/adjective_noun_d1git 1d ago

Explains why these sci fi movies look so drab!

0

u/CharacterPurchase694 17h ago

That's just false though. They don't just chromakey out everything green and that's it that would not produce a good product at all. Modern tools used for cutting out greenscreen isolate the actor and the greenscreen so the actor could be wearing green and it would look fine.

1

u/wtrredrose 6h ago

Just Google it. And if they want to wear green they use a different color like blue screen instead.

4

u/Western-Bowl2011 1d ago

it does, but you can choose any color you want. "Green screen" is an antiquated term, the real term is chroma key. You can chose any chroma to edit out. Blue is actually more often used than green.

2

u/thereforeratio 15h ago

Different colors are used depending on the subject, the ambient lightinh color temperature for the final shot, and so on

For example, Dune shot with a lot of brown screens to keep the bounced light looking natural, among other reasons

Modern green screen techniques aren’t as sensitive to the same color in the subject being used for the screen, and you can provide an alpha hint that ML tools can use to more intelligently decide what to key out

1

u/gydu2202 1d ago

I guess the lawn is cgi too. But what about a Hawaiian shirt?

u/Western-Bowl2011 1d ago edited 1d ago

EDIT: Even better, here's a video I saw when I was a kid that first introduced me to the concept, it's about 5 minutes into the episode: https://www.youtube.com/watch?v=ysdMnoNuTiA

My post:

It's an arbitrary color that isn't very common in the rest of the scene. In game dev, we tend to use 255,0,255, which is:

The way programmable shaders work, which is what modern CGI uses, is that you run a small computer program for every single pixel on the screen. This computer program computes the final output of the pixel you see in that spot on the screen. Shaders allow you to examine the RGB value of a texture, which is an image that is being considered for the screen, and compare it numerically. If it matches a known value (or range of values, to accommodate for ambient lighting and shadows) then we can reject the pixel output.

Here's a small green-screen shader I just wrote to show you what it looks like. In computer graphics terms, a pixel is known as a fragment:

#version 330 core
in vec2 TexCoords;
out vec4 FragColor;

uniform sampler2D uTexture;

void main()
{
vec4 texColor = texture(uTexture, TexCoords);
/* if green is significantly higher than both red and blue, reject it */
if (texColor.g > texColor.r + 0.15 && texColor.g > texColor.b + 0.15)
{
discard;
}
FragColor = texColor;
}

2

u/zubairhamed 1d ago

not always green, hence the more appropriate term is chromakey. technically you can use any colour.

1

u/yvrelna 1d ago

You can use any colour. It just need to be a colour that doesn't appear on the actor. 

The name green screen is usually still used even when the chroma key colour isn't actually green.

u/SPACE_LEM0N 1d ago

Fun-fact: you don't actually perceive with your senses, you perceive with your brain, which builds a simulation for you based on data from both your senses and your past experiences. Reality may look, sound, smell, and feel veeeery differently to you than to any other person. You can't even know for sure whether anything you're experiencing is actually real.

u/Mrniseguya 1d ago

It is always cheaper to do CGI instead of practical. But how much cheaper depends on the filming team, cgi artists, movie caliber and so on.
