I barely got a few things out of it since it uses so many technical words and describes the process in a way that you have to be an animator to understand it.

Anyway, i was wondering, why do they need so many hours to render one frame? I thought that they could render the robot in 3D and then make it move the way they want. Is it because they have to colour and light it realistically?

Also, the hardest thing for me seems the combination of the shots of the background and the CGI. Bay has to shoot precisely the shots precisely so that they fit with the fight ILM has made.

one second in the movie is build from 24 pictures.

so if you have 24 pictures moving you get one second. now imagine if OP is running on the street for 1 minute. thats 60 seconds. thats 1440 frames. so 1440 pictures. and one takes more hours to rende.
it takes a lot of time because the 3d models are very complicated(not because they are robots). then you have smoke,water,shadows. plus they are reflective. this also takes a lot of time.

when they animate they dont use shadows and tehy dont use realistic materials.all is in real-time. its basicly grey,whie,blue,red. after they are finished with the animation they add ligts,materials and then they render.

sometimes they prepare the fights on the computer before they film the scenes on location . they do this so that they know how the camera should move and where it should stand. but animation is done after the filming is done.

Thanks dark_b!

"Michael didnt want the robots to be. He wanted them to move like alien ninjas."
Great decision!

''Michael told us it was Spielberg’s favorite character in the movie. He’s funny, genuinely funny in the film.”''

Why Just 2 Seconds of Transformers 2 Took 3 Months to Complete

Yea, in agreement with dark_b. They model the thousands of individual pieces, using all real car parts for reference in a 3D app. They usually look pretty bland in the application window, they then rig it, making it able to pose, animate it and then render it in passes. Rendering is what makes it look real-ish. Passes are basically separate rendered images such as reflections, lighting,etc. They then take it and pop it into an editing program and composite all the images together, touching it up as they go.

They render in passes to cut down on rendering time and to keep their systems from freezing and crashing.

I think I am about right, anybody feel free to correct me or touch up on it.

 

[dark_b]

you are correct. also one of the reasons they render out in passes is so that they can do changes all the time.

for example 2 months after OP was rendered they can reduce the reflection on hes arms and legs. and belive me directors change their mind on this stuff all the time.

why the transformers are dirty when in robot mode and clean in car mode. ''artistic choice''
