That's what I got the 70% on. I got ~50% with some other clips though, like anime and Akiyo.

Cool to see something that could achieve similar results without manual ROI and with moving images.

It does even better than that, because, for example, when a bullet passes a background area, it will instantly restore the quality of said background area once the bullet leaves.

It naturally does a whole lot of these sort of things in addition to the obvious effect of locally optimal qcomp.

Would this help in scenes with foreign dialogue subtitles on moving background too?

That's one area I can see macroblocking issues with the current version of x264 on my encodes.

Sorry for my noobness

I use AviDemux so I need to compile libx264 DLL with this patch ... Can somebody point me to the right direction ?

Edit : Found It !

Your best bet there is to just lower AQ strength, but this might help there as well; I haven't tried it though.

Or do it right and use softsubs

It's some foreign dialogue hardsubbed in the source (BDRip).

And, it's only for a few seconds of the movie.

Is this patch going to be incompatible with vbv-buf max / b-pyramid etc. or is it only temporarily as they get implemented?

Doesn't seem to increase ssim on this test.

source = ep 5 of band of brothers. Blu-ray source.

B-pyramid should not be too hard to add, but it won't really work ideally until we get MMCO. Which should be soon, Trahald's working on it.

VBV may be a trickier issue; it technically "works" but the row-based prediction completely falls apart with MB-tree despite the support code I wrote for it, causing serious quality loss, especially in 1-pass VBV. It'll take some investigation to figure out exactly what's wrong and whether it could be fixed or not.

This sounds like the best thing since sliced bread!

Love sliced bread

Have to test this, will edit.

Seems wonderfull, perfect for stand-up shoots ;-) Thanks !

Same source as ssim test.

I guess the test is invalid, the non mbtree test has vbv and the mbtree one no ....

Is normal ? final ratefactor smaller by 4 almost ?

Also the mbtree build seems to ignore

param->rc.f_qcompress = 1.0f;
param->rc.f_pb_factor = 1.1f;

Does not show up in the mediainfo window, ipratio does.

Yes, because those parameters don't apply to mb-tree ratecontrol.

Yes, read again what I said about CRF in the original post.

If you want to make a meaningful comparison, at a minimum compare SSIM or something like that?

tetsuo55 · 3rd August 2009, 10:57

Does any other h264 encoder have a feature like this?
Does this have any influence on the decode difficulty?

EDIT:

And that really low bitrate anime example is simply amazing...

Almost surely not.

Here is a silly question!!

How fast does the motion have to be, to be affected by this patch?

EDIT: And that really low bitrate anime example is simply amazing... __________________ MPC-HC, an open source project everyone can improve. Want to help?
