Sounds like a smart compression technique that will especially improve the quality of anime encodes (if the animator won't add something like grain, like you mentioned). I don't think that it will really improve live-action encodes, though since they probably won't contain that many static scenes.

It reduces quality for the parts that are referenced the least. In a nutshell, this means the static parts of a frame can remain high quality, and only the more expensive (bit-wise) parts take a quality hit. Since our target was to get something that would be as close as possible to the Blu-ray, this is sort of nullified. There are still some relatively grain-free areas in Mouryou, but probably not enough to make a real difference for the file size. I was aware of mbtree while it was still in early development, but decided not to wait for it for the aforementioned reasons. You can see mbtree in action at http://mirror05.x264.nl/Dark/Flash/lowbitrateanime.html This is an extremely low bitrate clip. Notice how whenever something moves, everything in that area falls apart, while the perfectly static backgrounds remain beautiful.

If we had kept to scene quality standards, it would be about 600MB, and look nothing like the Blu-ray. I was going to link to about a million examples (screenshots from scene releases), but I'm WAY too tired for that right now. I'll do that when I wake up. Did you know: most scene groups copy paste x264 settings from some document published two years ago. Some even use very old versions of ffdshow to encode.

I also forgot to thank you in my original post, so thank you very much for this show! It's been a long time since Fall '08 and it's sad that a show like this hasn't been subbed (completely) yet, so it's great to see a group changing that. Sounds great.

Would using that make the size less than about 1 GB while keeping the same quality and if so, is Norikumi going to use it?

The grain was meant to be there and taking it out would detract from the feel of the show. We decided to leave it in for purist's sake and we ended up getting a 1GB episode. Sorry, but that's the way it is. And also… yeah, I guess I may have went a bit overboard, but I still think all my points stand.
