Still would like some working multithreading up in there.

What's the problem? Works fine here...

maybe whining that it's not as fast as b-adapt 1?

just use a sane number of b-frames.

[Soichiro]

Of course it's all my fault if it's being slow. Of course I'm just whining and being stupid. -_-;

I am using a sane number of b-frames. It's set to 6. And while it's better than before, it still doesn't use all of both cores with --b-adapt 2, which is something ideally I would like to see fixed. It's not too crippling on a dual core (though 70% CPU usage isn't something to be happy about either), but I imagine the new method would cause much more of a slowdown on a 4+ core system.

[Sharktooth]

6 is not sane... 3 (or 4 maybe) is...
and as Dark_Shikari said, even 2 with b-adapt 2 will look better then 16 with b-adapt 1.

[Soichiro]

Well my tests show that 6 is a good balance between speed and quality for animated material. Almost all my anime encodes have shown large (10%+) b-frame usage in up to 6-frame sequences, while beyond 6 frames is below 1%. I would call that "sane".

[Sharktooth]

not with b-adapt 2... using 6 b-frames will kill the encoding speed, so it's not a good balance.
use 3 b-frames with b-adapt 2. also for animes, maybe you better stick with b-adapt 1 and 6 or more b-frames.

Has b-adapt 2 shown bad results on anime? o.O

No, I haven't done much testing on anime.

The question is whether you lose more from the lower --bframes than you gain from b-adapt 2, and I highly doubt that is the case.

[Sharktooth]

no, but since anime encodings will be happy with more b-frames, b-adapt 1 is faster and probably will be not much different than b-adapt 2 with less b-frames.

We don't know this for sure Some testing will have to be done.

I have some anime clips that benefit tremendously from b-adapt 2. Though it might be because they're full of fades.

[Soichiro]

Ah, that makes sense, then. So I should keep using the old method until the new method is more optimized/properly multithreaded, then (unless I have extra time to kill ).

Thank you. ;D

[Quark.Fusion]

AFAIK --b-adapt 2 can't be multithreaded as it relies on it's previous result (correct me if I'm wrong). Get process explorer and see how much cpu b-adapt thread uses, if it's greatly lesser that 100%/(num of cores) — try thread-pool patch.

Thanks

If the next 21 builds come as quickly as the last 21, we will be at r1000 in 2 weeks...... wow....

It's not the quantity changes, but the QUALITY of the changes that impress me though! Thanks Devs!!
