DivX 6.2.5 now available

[DigitAl56K]

DivX 6.2.5 has just been released and features much enhanced post-processing and playback performance.

You can see benchmarks and an interactive demo of the new post-processing here:
http://www.divx.com/divx/windows/codec/features/

This point release is decoder-centric.

rock on dude, that post processing sharpening feature rock, by the way, how can i make my dvd to divx encodes sharper during encoding, using mpeg-2 quantization, or that enhance texture feature, or both?

DigitAl56K is this somekind of SeeSaw implementation ?

@ DigitAl56K

Can you make a update patch from DivX Pro 6.22 to DivX Pro 6.25. I can't download 14.2 MB.

"Full Deblocking with Sharpening"

Perhaps special PP4 with very better high frequencies preservation. If yes metric would be better. If not it's just post process sharpening filter like xsharpen or msharpen in ffdshow. Anyway "sujective quality improvement" seem really good.

[CruNcher]

Sagittaire yep it definately looks better for High Bitrate this appears to me to be somekind of H.263 Matrix Blur workaround. DivX Inc seems to fear AVC, it doesn't seem to work on the DCT level tough, so only a post pro filter in the Decoder, nevertheless it seems it doesn't really preserve details, so it's a trick :P
calling this Sharpening hmmm not sure maybe Blur On/Off would be a better name for it ;)

[Warrex]

The interactive demo looks absolutely spectacular!

Unfortunately I do not get the same results when using the new decoder. The frames look even more blurred when using "Full Deblocking with Sharpening" compared to "No postprocessing". Tried several 720x400 files (1500kb/s-2500kb/s). Film effect was turned off.

Is there a way to test "Sharpening" without "Automatic Deblocking" turned on?

[DigitAl56K]

Warrex - Make sure you rebooted after installation if prompted so that your DirectShow decoder is updated. You should definately see the effect.

Sagittaire: It is a post-processing effect. You will find metric to be lower but subjective much better, as you're seeing :)

CruNcher: I haven't heard of SeeSaw before, I'll take a look at it.

P.S. Hah! @ Blur on/off ;) The decoder is enhancing details on playback, so we can do this for any DivX video.

[Warrex]

Actually I did reboot twice since I installed 6.2.5. However for some mysterious reasons I had to un-/reinstall DivX to get it working.

Looks sweet! Great job!

same here

[DigitAl56K]

Sure, I can work on that. Time allowing, I'll get something up on DivX Labs tomorrow and post the link.

[Soulhunter]

Lol, thats the first time I installed DivX since 5.2 ;D

Hmm, slight ringing... >.>

But better than conventional sharpening it seems!

New 6.2.5 decoder is 29% faster here.

Comparing it with old measures http://forum.doom9.org/showthread.php?p=813278#post813278

MPEG4 video (no GMC no qpel)
Divx decoder custom+full deblock - 54.2 - 54.5 fps
Divx decoder full+sharp - 39.2-39.3 fps
ffdshow mpeg-4 decoder PP2 - 72.0 - 76.5 fps

AVC video ( encoder: x264 full featured High Profile)
CoreAVC decoder (standart deblocking) - 54.3 - 55.2 fps

New sharp feature rings a lot.
Sharp of the details isn't the same thing with the sharp of edge contrast.

Looking at screenshots it is impossible to see ringing and another issues of this kind of sharp. I didn't test it at high bitrates but at 650-700 kbit/s it had too much contrast.

[CruNcher]

Yep it's got faster but CoreASP is still the fastest :)

see that's no fair if you've used it already because it's not public yet lol

[DigitAl56K]

For those bandwidth afflicted folks who asked, here (http://download.divx.com/labs/DivXcodecUnofficial625Patch.exe) is an absolutely unofficial and unsupported update patch from codec 6.2.2 that I whipped up tonight. Hope it helps :)

[Kostarum Rex Persia]

DigitAl56K, just one little question fot you: that update patch which you so kindly provided, is it update to 6.25 or 6.25.17, which is bugfixed version.

[DigitAl56K]

6.2.5.17 :)

[Dyolfknip]

I opened an AVS script in lastest version of VirtualDub (1.6.15 stable) and selected DivX 6.2.5 as video codec. Codec properties window opened as it should. Then i decided to use presets and I set the slider to far right (quality 10). Then I wanted to change max keyframe interval and un-cheked the presets checkbox on main tab. Then I set max keyframe interval to 240 frames and clicked OK (settings seemed to be OK at this point). After that I decided to check the settings once more and noticed that encoding mode was set to Balanced (it was insane before i clicked ok) and quantization mode was set to h.263 (was h.263 optimized). Other options like bitrate were just fine.

CruNcher... play nice ;-)

[CruNcher]
