A comparison of the difference between the recently released Blu-ray edition of Index-tan anime A Certain Magical Index (on the right) and the digitally broadcast version (on the left) emerges.
The difference is as night and day… In fact it seems a little extreme? Poor encoding, perhaps?
Those who are still not convinced can view the full (same resolution) 10mb png here.
Sure, there are differences, but anybody who really cares is a BluRay fag.
It’s quite silly to show screenshots of Blu-Ray at such a low resolution. The entire point of the format is to look good at high resolutions. If you compare DVD to Blu-Ray at DVD resolution, of course there’ll be no difference. If you compare it at Blu-Ray resolution on the other hand..
Still, Japan has been known to be awful at mastering shows for home release, and when given the source to other places, like Madoka and the Italian release, they will do a better job than they did in their home country.
10MB PNG FTW!!!! =3
The quality difference on the full quality image does seem fairly apparent to me except on the fourth example (though you can still see it in the background there), though I would say it’s almost certainly not as noticeable when the video is actually in motion. That’s not really why I’m posting though.
My main point of commenting here is that the full quality PNG seems very badly optimized to me. The original, as hosted here, is approximately 10.9MB, making it a very large file. After sending the same image through OptiPNG (http://optipng.sourceforge.net/), I got an image of exactly the same quality that was only 7.4MB in size. That’s a reduction of nearly 32% over the original.
The exact options to produce this (at least on OptiPNG 0.5.5) are “-zc9 -zm9 -zs1 -f5”, I could also upload this optimized image somewhere if Artefact wants to use it instead of the original. Low bandwidth users are sure to appreciate it, as is the server.
It’s ok – I doubt many actually used it as the 90% jpg is pretty much identical for most aspects of the image…
Ohhh the difference is ENORMOUS….. no… I just…. no…. Untill they stop selling normal dvd’s…. I won’t bother with blu-ray…. I’d have to own a full-hd tv for it to make any real difference anyways….. I wouldn’t get it for anime at any rate. For HD Tennant/RDJ/JDM maybe.
