May you upload somewhere a 2sec lossless clip (1sec before and after the frame you have chosen for the comparison)? I'd like to make an experiment... (^^,)
A question: did you use Infognition SuperResolution plugin? If not, may you post comparison also using that? Thanks!!!

Handbrake uses lanczos3
Thanks for the info!

@LaserDisc Master I used handbrake to downscale the 1080p original using the h264 codec at 8000kps.
But which kind of filter? Bicubic? Spline? Lanczos? Other?
DrDre, which algorhythm has been used to downscale the BD?

It would be interesting to try it on something that already looks good, some very well mastered DVD release. (Avatar maybe? Wasn't that one considered one of the best?) And then comparing it to a simple Spline64Resize in avisynth.
Yes, we should start an "upscaling war"! (^^,)

I've now done lots of still comparisons with WOWOW vs. grade-matched BD and I can honestly say that the WOWOW, surprisingly, has more detail.
Good to hear that... I thought to be completely crazy... (^^,)
Great results, You_Too!
A question: did you use the NTSC GOUT DVD as source?
Forgot to mention I added also a grain plate...
Agree, less small details, but more precise borders and less artefacts... for example, look at Obi Uan's cap profile... it's full of "jagged lines"... different methods, different results, subjective quality! (^^,)
SuperResolution Vs BasiClean+MagicUp:
Needed improvements on fanres done:
We are ready...
Really interesting; I prefer the HDTV color grading.
But I'm curious to watch also the 1080i version, and possibly make a comparison between it and the 720p.
It will be great to see some examples using very good DVD, and compare the result of superresolution with the same title in BD (that, of course, should be of high quality, too).

To me it looks like it has some standard up-scaling artifacts the way you do it. The superres one looks softer but cleaner, and generally more appealing.
Indeed, I used one of the most simple upscaling filter, but have you noted the problems on the superresolution version? OK, I must admit they are very tiny - infact you have to zoom in a lot to see them - but they are there... look in particular the eyes...
I expected much more quality, according to comparison examples...
Don't know if this is due to compression artifacts (even if I don't think so, because 20Mbps should be enough to avoid them), but it seems that the superresolution algorhythm you are using is not that effective... a simple avisynth bicubic upscale, using the compressed MKV SD video you provided, sharpened a bit, seems very similar...

what do you think?
What NeverarGreat told is true; take a look for example at the two pinkish tubes on the left over the stormtrooper's shoulder, at Leia's hair, both troopers "eyes" and "noses"...
There is something wrong in the upscaled video... don't know if it's due to encoding... just take a look at frame 100:

may you post the same frame, but lossless?
First: thanks to AntcuFaalb for the idea of using the grainplate; kudos!
I used a grainplate on The Arrival, and final result is good, in particular because there were almost no grain in the BD I used as source...
I added a grainplate also for the replacing shots of AVP:R taken from the DVD, to be similar to the BD.
Visit fanres.com and sign up; there are very interesting topics there, and I don't exclude to write an article about grainplate sooner or later!
Advice: you should use NTSC DVD for EP IV and V, and PAL for EP VI, to have the best quality.
May you post somewhere five consecutive, lossless frames of the source before upscaling, and the third frame upscaled? I'm just curious to see the difference between the process you are using and mine! :D

I should test a newer version of TSmuxer along with MultiAVCHD... someone would like eventually to download a test disc, and waste a BD-R?
Still need to find some time to do it :)
MY FAULT, MY FAULT!!! Sorry, with all these screenshot comparisons, I exchanged images by mistake... so, what I presumed contrast problem in the 4K BD, is indeed in the pre-4K BD... apologies to everyone...
Let's say that BD 4K has the "right" color grading, but it has also contrast problems, while the BD pre-4K has the right contrast, but not the color grading... well, as the contrast problems could not be completely solved, we could just regrade the BD pre-4K using the BD 4K as color reference...

Spoiler: GB2 is almost ready, I need some time to finish current projects, so can't say when it will be released...
What do you have planned for GB2 Andrea? The black crush on the 2014 blu-ray does look bad in those comparison pics, particularly the one in the sewer with the pink slime...
