The HD-DVD version is slightly more detailed. Debris on the floor, flashlight beam, badge, etc.

Everything else is typical: mpeg-2 is more noisy/grain, vc-1 is more smooth.

On the second set of frames, the upper left hand corner (especially along the pipe) is pretty blocky on the Blu-ray frame.

BTW, it would be nice if these pictures were labeled. I don't have a clue as to which movie this is from.

not seeing that- looks pretty much identical to me, especially if you check the waggles- I thought I was seeing differences until I checked those.

I forgot about the set of pictures on the previous page, so I really meant the last set of frames. The ones with the two women in them.

it just looks like noise to me rather than macroblocking . . . .the mpeg 2 is definitely noisier overall in this comparison

You are pretty forgiving. But then I'm an encoder designer, so it's possible I have an eye for this stuff. Here's close-ups of the area of interest.

Blu-ray



HD DVD

Yes. Even before the comparisons we already know the end result on this one.

Honestly the transfer is not consistent to begin. Its basically outdoor scene = clean and sharp then indoor scene = grainy and some details gets lost.

Not to get too analytical but the mpeg-2 version of the 2nd capture has more shadow detail if you crank up the brightness in the 2nd pic. The vc-1 encode seems to clip directly to black whereas the mpeg-2 is more gradual:



The mpeg-2 encode has a little bit of a red push in it for some reason. Maybe it stole it from the Flags of Our Fathers comparison.

I used Haali renderer on both for Silent Hill. Is it the same level as Flags?

The HD-DVD of Flags had a red tint. The BRD was kind of green. I have no idea what was correct. The red push here is much much less and can only be seen if the gamma is increased.

Personally I wouldn't use the Haali renderer. From the tests I've run it doesn't display grayscale images correctly. It introduces some red push but I don't think that's the problem here.

I am thinking of redoing the Flags again. That red and green tint bugs me. I have a different video card and drivers since then so I think I may see some difference.

Weird. I didn't much care for the movie but always figured it'd be nice to own since it'd at least look great and has a few cool parts, glad importing is an option. Thanks for the screen shot comparisons (any word on a Blu re-master? I can't imagine it was a particularly huge movie).

I can't say I'd notice the difference while watching the movie with absolute certainty (I watch movies on a 109" 720p setup) but the difference is definitely noticeable here.

The only real difference in the last image is the BRD is noisier in the shadow areas and HD-DVD is slightly clipping out detail. You probably won't even notice if your display is decently calibrated.

Is that an antenna near the bottom right hand side of the rear window on the MPEG shot? I do not see that on the VC-1 shot at all.

Also, are the bitrates of each of the encodings known or is that info that is not available? It would seem that the bitrate would make more of a difference than what type of encoding is used anyway.

Samsung SMT-H3272 - Nav.7.1.2.1
SA 8300HD (no C) *AZiO ENC311SU41* eSATA- WD black- 1TB - it works!-
-8300HD no more because TWC deliberately made it unusable in my area! :-/ :-(

I think the VC-1 encode is slightly bigger than the mpeg-2.

I don't see any antenna, just noise. I still think the mpeg-2 version has better detail though, or at least better contrast. The smoothing effect of vc-1 is really annoying. Is there any way to turn that off?

I have a difficult time believing that those images are from the respective discs. For one thing aren't they both the same encode?

The contrast/gamma/colorspace looks completely off between the two images.

One is from the HDNet broadcast, the other is from the HD-DVD/BRD. The 4k mastering is worth every penny. Too bad 2001 didn't get the same treatment.

Yeah, I don't get it. Why the huge black crush? And why the green tint too? Feels like the Matrix all over again.

It does blow away the HDNet in terms of detail though.

The HDNet version has the typical MPEG-2 RED cast which is replaced by crushed blacks and green tint on HDM. Why on earth are there people who want to deliberately take-off some essential picture elements !!!
