I couldn't find how the DVD screenshots were taken - with the volume of pictures in this thread it was impossible for me to find, if it exists!

Anyways, the DVD screenshots look excessively soft. My upconverting DVD player does a much better job (upscaling to 1080p) and looking at 1.0x screenwidths distance. Maybe they should be resized using Photoshop's Bicubic filter?

FFDShow's upscaling is better too - LanczosResize() in an AVISynth script. Significantly better than the shots here I think. What am I missing?

DVD screenshots were taken from a MPC using DScaler upscaled to 1920x1080 resized using Photoshop Bicubic filter saved as PNG.

Having SD and HD in a side by side comparison, the softness or lack of details is more apparent on DVD. You guys are welcome to post a DVD screenshot using some other software to make it sharper but at the end of the day it wont change the result.

Xylon, thanks for the info.

Hmmm, so the native resolution of playback in MPC is 1920x1080, and then re-resized to the same resolution but with the bicubic filter? Strange. It still doesn't look right to me, but then again I use FFDShow, which I assume you're not using in MPC. That could explain it.

It will be a few days before I can make tests with other DVDs. I have very few HD-DVDs and I don't have DVDs for most of those titles to compare against.

Maybe someone who uses FFDShow with the AVISynth scripts that 8:13 posted in the HTPC Forum Sticky can do us a service and take the same screenshots of the DVD versions?

I definitely agree with you - even my early screenshots of the first HD DVD releases from my 1080p DILA projector with my Canon 12 mp camera could never get a true pixel for pixel match and connot hold a candle to a true digital capture.

It's ironic that we have the hackers to thanks for our newfound ability to make VERY good comparisons.

I'm interested of course. I probably have those versions already. I will let you know if I need a particular screenshot from a movie that I don't have.

Yes, I suspect that you are an HD techno-connoisseur just like me! Still, I have access to some satellite material for a few relevant films should you need it, such as:
Blade Runner
Underworld Evolution
Fifth Element
Into The Blue
The Brothers Grimm
The Perfect Storm
Poseidon
Mission Impossible II
Syriana
RV
Hitch
Million Dollar Baby
Etc etc etc
...some of this material is in AVC also.

I would also suggest that you capture some "hi action" frames as well, from the respective sources, to demonstrate how these codecs react to stress. I still remember my amazement when I first saw The Last Samurai in VC1, after having watched it on a DVHS for so long.

The extra dollars I spent on it is worth it. The PQ is consistent unlike some HD titles I have seen.

Again I agree - I bought Harry Potter HD DVD when I was last in England. Superb PQ and contrast all the way through.

Your work in helping folks see the full image of these releases is much appreciated - your captures are incredibly helpful in these comparisons.

Ahh... F1 in full HD 3D with

To clarify further, the DVD original capture file is 850x480 BMP 1.60 MB upscaled to 1920x1080. The HD meanwhile is 1920x1080 BMP 8 MB file size reduced and converted to PNG same rez.

Lots of work. Who's up to it? I'm interested to see the difference as far as DVD upscaling is concerned.

Also that last wide shot of Fantastic Four looked like a bit of a struggle for Mpeg-2.

Batman did look a bit soft in that shot but on my monitor the HD DVD looks much sharper during playback .

Batman and Superman looks soft and I don't have a problem with that. It has the same "soft look" when I saw them in the movies. Soft but everything else as far as PQ is concerned is superb, details, saturation, blacks etc., etc.

Just look at the SD versions, YUK!

Even at 50% magnification the dvd shots are still lifeless and flat. Sure, you can scale them via ffdshow, sharpen and denoise the hell out of them but they'll never be more than SD.

Yeah no kidding - I can't take the screenshots you made because I don't own the DVDs. In fact, I don't own DVDs of the HD-DVDs I have! Ooops.

Great idea. What about creating a real SD <-> HD comparison page. I'm sure there are lots of other titles a comparison would be great.

The whole battle scene with Doom looks like that. It gets worse when the Human Torch starts flying around. You can verify this yourself by watching it again but this time look closely at the crowd or buildings surrounding fast motion objects. The colors and details stands out fortunately over DVD but the rest is sub-par to me at least.
