HCenc 023 released

Major changes:
- added adaptive quantization
- added panscan

And as usual some bug fixes.

Thanks to the beta testers and those who provided sources to tackle some nasty bugs.

Awesome news! And thanks for great encoder!

I am quite curious about the new AQ. I will test it soon.

Btw, does your AQ have anything in common with VAQ used in x264? Or does it use completely different algorithm?

Regards,
Irakli

Thanks,

Hank,
Thanks for the release of HC023, also for adding the button to specify the lossless file location. An additional donation on it's way.

I really appreciate and applaud your efforts. Keep up the excellent work.

Sincerely,

rcubed

Thanks very much Hank!

And I already need some advice concerning the new "Adaptive Quantization" feature.

To avoid blockiness in flat scenes I so far have used "Lumgain 3" quite successfully. Now it looks like I can get the same effect by using adaptive quantization. Which one of the two methods is the preferred one? Or should both methods be used at the same time for optimum results?

Cheers
manolito

Yes, the links are dead ATM.
Already mailed them, will be fixed soon I hope but the link provided by smok3 does work.

I don't know exactly how it is implemented in x264 but IIRC it uses a variance based decision method, something similar is also used in HC023.

Hello hank315,
Good work..

Why have limited the number of B frames to 2 (in GOP Structure)?
Can you adjust the AQ Strength decimal (0,2; 1,3...)?

Bye.

Thanks for the info.

Probably because DVD Video standard supports up to 2 consecutive b-frames only.

from HC PDF documentation

Quote:
*B3
parameter - type -
Status not required
Default -
Example *B3
This command allows 3 consecutive B-frames, NOT DVD-COMPLIANT.

Thanks Hank!

Will *AQ > 0 use *MATRIX or *CUSTOMMATRIX as the baseline matrix, or will it instead use a hard-coded one?

hank,

i would like to say that your encoder is the best to hit higher ssim and psnr value...it manages really well HD clip and it is really tunable ( just i would like also 1pass vbr as in CCE beacuse i need for some test i'm doing...) and its second pass it is amazing to goal the exact size i want!!

big work.
thanks!

ciao
