These movies are done with the actual engine, and are almost certainly un-edited direct feed videos, as they don't have as good image quality or motion blur, as GT3 intro. You can see some shimmering, some aliasing, etc. especially in the videos that show gameplay point of view.
If anything, motion blurring appears from downsampling 60FPS footage into a 30FPS video.
Both tracks look really gorgeous, btw.

The trick where the current frame is blended with the last rendered frame is cheap on the PS2 but it's NOT motion blur.
It's pretty clear from those movies they used the same trick used in the GT3 intro. Each frame is taken from the realtime engine and post processed offline (so you have the same texture flickering from the realtime engine..). To perform 'real' motion blur one have to render a frame N times for all the time the camera shutter is open, not just blend together N frames from previous rendered frames. (that's just a low pass spatial/temporal filter)

What's with no head lights? Do you think PD are going to do them right in GT4 because in GT3 they were weak.
Frame rate is not determined by the camera shutter speed.V3 said:
Given a sampling rate of the image, N samples fit in one frame.
How big is N? it depends on lot of parameters, like cel/ccd sensitivity, shutter opening end closing time, total amount of light in the scene, objects maximum speed, etc..
Making it simple you just sample N images and accumulate them in one image

Which is exactly the same as "fake" PS2 motion blur when
shutter speed == frame rate...
Not really, if shutter speed is frame rate then you simply get no motion blur with the scheme nAo is talking about.
The motion blur nAo is talking about will not reuse temporal samples, each sample only contributes to a single shown frame. That is not to say there can be no artistic use for effects which do reuse samples ... but personally I would call them motion trails rather than motion blur.

Er, I must be blind, but these videos don't have anything even *resembling* the high quality blur from the GT3 intro. Not to mention they have other image quality flaws here that GT3 intro didn't have... It looks exactly like any video from GT4, as far as image quality goes, no better and no worse.
The only blurring that I see here is made from motion artifacting due to compression, and 60-30FPS squeeze :?

I can see it, but as I've said, that is the exact same kind of blurring you get due to motion artifacting while compressing a video stream, and by bringing the 60FPS footage down to 30FPS video, where frames get interpolated.
It confuses me why certain individuals automatically assume that the presence of texture aliasing automatically equates to realtime...
I don't know about some people, but I have seen texture aliasing in prerendered CG FMV.
On a similar note, CG using in game models and textures does not equate to realtime either ie GT2 intro.

Agreed. And also in REALITY while watching DVDs........
