Cvs 2002-02-27
Changes:
- Foxer's asymmetric curve compression file size fix (should be very very accurate now). - Separate I-frame and P-frame quantizers for fixed-credits-quantizer mode. Be warned, file sizes will change when credits-i-frame-quant != credits-p-frame-quant. Difference shouldn't be huge, however. -h |

Hey, just a little more patience.
You can't imagine how ODD it is to apply the same modifications over and over again and the next day again because there is some real bullshit in the code etc... *GNARF* Koepi

Anyhow:
XviD-27022002-1: - fresh checkout of the CVS sources with curve treatment bugfixes - reimplemented quantizer type modulation Follow the XviD link in my signature. Regards, Koepi

Ahh, I knew that i could trust you
I will get right on donwloading it. I just made a quick test using Nic's build, using the asymetric curve parameters (240;15% low, 25% high) and just this: my target file size was 10466, and i got 10460. Good stuff, heh? Quality was good has always.

By the way...
Why isn't the modulated quantization option already placed in the codec by default? Like me and Franko30 (right, Franko30? , i believe that there are out there lots of users who like it too. And the other options are still there for the ones that don't like the modulated quantization. Then, poor Koepi wouldn't have to read the anoying screams from guys like me asking for a new mod of the latest build

There's going to be an API change from Isibaar ("soon" *lol*), which incorporates the framebased quant type modulation.
Btw., there is still some serious bug within the actual builds. Directly after first pass started a second pass and got horrible scales/quantizers. (e.g., filesize already reached was half size of the overflow.... it used less bits than the sound!) Looked like the "scaled to" variable got stuck within the range 1079-1082 (always fluctuating in that range), and the actual frames got something like 100 bytes, 500 bytes,... totally wrong. Stopped that, checked my values, started again - now it looks ok.... thats so weird and annoying :-( Regards, Koepi

Adding quant modulation to the code would be nice; although I'm going back to h263 only, as stated in my post to the CVS 2002-02-26 thread. Now it's time to download the newest fixed builds and encode a few more movies. Cheers Franko |

But you're not alone, I guess a lot of other people like Quant Modulation, too . And I would be using it still - if I would do DVD backups. But my source material just looks better with h263 only. Frank |

I#ve to agree there, for more noisy sources like TV captures it's unlikely that quant type modulation looks as good as for DVD encodings...
Regards, Koepi P.S.: you're definatly not alone, since I like quant_type modulation and use it all the time.... P.P.S.: I'm doing a third encoding with the new build and that bug I experienced seems to be gone. Dunno where it came from, maybe wrong values in the registry for the first time after installing... (hopefully)

I ran once more into the second pass trouble.
I solved it by using the open-dialog for the stats-file... Seems like the error is located there, some filehandle not cleaned up or something... Regards, Koepi

Settings 576*240 Soft Bicubic with T.Smoother 2,1 before resize M.Search:6 H:263 MainQ Min:1 Max:6 I-Frame Min:2 Max:4 S.Quantizer: ON No L.Masking No Creditfunction(encoded manual Q:16) Payback:240 C.Compress High:25% Low:10% First pass size:718 LOL DivX DSfilter Well i dont have any luck with this movie it look worse and blocky as hell in some scenes(Low motion).I have better result with this movie in the builds with no Curve compression even with out T.Smoother. Is there something to try? I can send a clip or some pic's if you want But the filesize was very good 50KB oversized
