DIVX 6.2 beta

[sbp]

Hi DigitAl56k

I would like to try the new codec, but it is stated on the page that it will expire (it doesn't tell when - 3 or 6 months?)

I have a registered DIVX 6.1.1, what will happend with my DIVX pro 6.1.1 when the 6.2 Divx pro functionality stops after the beta period expires? Should 6.1.1 then be installed again?

Steen

[Romario]

Nice, I knew that new beta will show up about this time?

DigitAl56k, can you explain new features to us? And, what's the plans for the final version of DivX 6.2 codec?

[IgorC]

New enhance texture provides more details (especially on low motion) but at cost of little blockness.

" Enhance texture" is a new Psychovisual Enhancement method that improves quality for keyframes and reduces the appearance of stray blocks under fast motion. As with other Psychovisual Enhancement methods, the perceptual quality can be higher, although the PSNR metric RD performance is typically lower.

The step into right direction :)

[fight2win]

maybe digit is not replying seeing what kind of disrespect divx gets here. Cool new features, DivX rocks. Maybe the fools here forgot even their beloved xvid was a mod of divx.

[ChronoCross]

umm....are you high? xvid is the open divx standard. it's not a mod of divx in fact you can be sure that almost none of the code looks the same or is organized the same. It's faster, higher quality, and completely free. I'm pretty sure that xvid is based on the open standard mpeg-4......not on divx.....divx is not mpeg-4...it's simply an implementation of the standard.

On the thought of divx getting disrespect I disagree with you. just because there is alot of discussion on people not liking divx that's simply a product preference, not disrespect. If I like a sony product over a toshiba product that doesn't mean I despise toshiba, it simply means I like sony better....see what I'm saying?

I happen to like their web player, just not the codec itself.

[manono]

Cut it out, fight2win. You've been warned.

No need to take the bait, ChronoCross.

Hello all!

It's good to be back here on the forums! I've been a little absent of late due to some busy times at DivX, but I'll try to check in often for feedback or questions around the beta.

Steen: This particular beta will time-out mid-April. We will either have newer betas or a release version out by then, but if you like you can also re-install 6.1.1 over the top. None of your registration information will be lost.

Romario: We'll have some more feature changes before we go to release with 6.2, but in this beta we've added several performance and quality features.

For older processors, we've added an MMX version of the MPEG quantization method that will improve encoding rate around 22% (when using MPEG quantization).

For HT, SMP, Dual core processors we've added threading optimizations to the built-in resize filters. The gain in encoding rate will depend on your processor configuration and will be most noticable in the faster encoding modes. I see over 40% improvement in encoding rate on my Pentium D Extreme Edition CPU when encoding in Balanced (default) mode.

We also added an "Enhance threading" option whose benefit really depends upon the particular tools and processes you are using to encode, as well as your encoder settings. In the worst case you'll see no benefit from enabling this option, but in the typical case we see around 16% improvement. In the best case on my PDEE box I see up to 35% gain in encoding rate. For this beta, I'm particularly interested in how this option works in your favorite encoding applications. Let me know if you find any that have problems if this option is enabled.

Finally, we added an "Enhance texture" option that improves texture around keyframes and should reduce stray blocks under high motion (which are particularly visually disturbing at lower bitrates). I personally find this makes a large difference to facial texture around keyframes.

As always, thanks for helping us to test the next version of the codec. It is much appreciated.

[bratao]

Thank Divx guys for this version.
In 6.1.1 i get a too variable speed(always 30-50 fps) .
With 6.2 i get a solid 50 fps !
thank for this release !

[DigitAl56K]

Two reminders:

In this beta version Enhanced texture is on by default. This means you will get better quality around keyframes but PSNR metric RD will be lower. Enhanced threading is off by default. You have to explicitly turn it on to use it. This is partly because we have not yet tested it with a wide range of applications (this is where you guys come in!).

[fight2win]

Cut it out, fight2win. You've been warned.

No need to take the bait, ChronoCross.
Warned for what? when u guys disrespect divx, no one warns u. when i say divx is good, i get a warning? Are u George Bush?:sly:

[manono]

Warned for what?

Warned, and now struck, for a Rule 4 violation. If you think you've been treated unfairly, you can take it up with Doom9, following the procedure outlined here:

http://forum.doom9.org/sanctions.htm

If you're the same fellow that stirred up trouble some time back under the name of Neo_andreson, then I suggest you just lay low for awhile.

Soooo.. about that beta.. ;)

[Romario]

I can't download new beta, I don't know why. Probably my slow dial-up connection is guilty for that. But, as soon I download 6.2 Beta 1, I will post results.

[IgorC]

Looks like divx 6.2 came with usefull 3 pass.
Before Divx 6.1.1 didn't make noticeble difference.

divx 6.2 ( Insane 3 passes ) has the approx. same speed as divx 6.1.1 ( insane 2 passes) on onecore.

[Avish]

Hi DigitAl56K, looks like you are a DivX Official.:) So I wanted to ask this one question for a while about DivX that Why your bundles are so big in sizes? Play bundle is 15mb and Create bundle is almost 17mb. Most of the other codecs I know about, are below 1mb. So the size difference it Huge! Is it not for dial-up users? And is it not possible to provide only the Codec without player and any other stuff? I wanted to try this beta, but your site says that it's required to install the Create bundle first but I don't want to download it coz it's 17mb. So any solutions for this?

[Millenod]

An other question to DigitAl56K

is it possible, as in older version, and other codecs, to don't have a icon in the systray when playing a movie?

divx6 looks very "heavy" to play a video...
it's very sad, on a P4c@3Ghz with 1Gb DDR.
I have the impression to use a not finished product. "xvid" looks better and fast to play movies (i'm playing movies with MPC)

but to encode movies, the profile named "extrem" is really good! perfect!
good job for the encoder!
And if you need testers, I hope you'll contact me.

regards

Hi Avish:

Our bundles are a little larger than most codec downloads because they don't solely contain the codec. As well as the VFW codec and DirectShow decoder, there is also the DivX media file splitter, settings manager, update checker, DivX Player, DivX Web Player, DivX Converter [in the Create bundle], localized resources for all products for French, German, and Japanese, and yes, a couple of offers from Google ;)

You need to install one of the bundles from our website to use this beta because to conserve file size I did not package all of the library dependancies with the beta installer itself.

A recent poll (http://labs.divx.com/node/128/results) on DivX Labs revealed that for most people the download size was not the largest concern around our software, but we do agree that a smaller bundle containing the codec would also be nice and this is something Gej is looking into.

Unfortunately right now you will need to download one of the main bundles from DivX.com before you can use the beta.

Millenod: I added a method in 6.1 and later to disable the settings manager for specific applications. Using RegEdit, add the image name of your media player here:

HKLM\Software\DivXNetworks\DivX\SMExclusions

Another tip is that if you want to leave this on, exclude "DivXSM.exe" and "qt-dx331.dll" in your Windows\System32 folder from your anti-virus' real-time protection system. This will speed loading of this component.

Ultimately I also want to re-architect this piece of software to make it much lighter, it is just a case of resources and priorities for our team.

Thanks for the feedback guys :)

We must say that a total of 720 votes isn't really a good statistic. I don't have any problem with 18 MB files, because I have a 6->8 mbit DSL, but a lot of people who already have downloaded all the stuff inside and just want to try the new codec can find this a little disappointing.. :)

[DigitAl56K]

It is better than a total of 719! ;)

but a lot of people who already have downloaded all the stuff inside and just want to try the new codec can find this a little disappointing.. :)

If they've already got all the stuff inside and want to install the beta they should have no problem ;) You only need to download the bundle when you don't already have 6.1.1 installed.

Anyway, I accept your point that the bundle might be considered a large prerequisite for the beta codec by people with slow connections, but I hope most people will have 6.1.1 installed already.

How are you finding the beta version? Is it nice and stable in your video apps?

Hi DigitAl56K,

Thanks for the reply. But I already know that bundle contains all the stuff u mentioned and thats why the size it so big. My "Why" was in different reference ;) What I was asking that, Why u need to cramp all the available stuff into one bundle? I never use DivX Player, DivX Web Player, and DivX Converter [in the Create bundle].

Anyway, I'll look forward to "smaller bundle containing the codec." :D Any idea when will that be arriving? ;)

Thanks.

[olnima]

Hi divx-people out there,
are there any plans to implement AR-Signalling without resizing
(the way, xvid does)?

Greetz
Olnima

[DigitAl56K]

olnima: You can, but it won't work on DivX Certified devices.

In the decoder configuration utility turn on "Use advanced hardware overlay" and set the "Aspect Ratio" drop-down to "Original".

Then you can encode your content without resizing to 1:1 and use a PAR changer on the file (I think there are a few linked here on the forums).

[CruNcher]

Anamorphic Bitstream signaling out of .avi works on the newer MediaTek Firmware just fine
The Zoran Firmware doesn't understand it yet only via NeroDigital .Mp4

...using an extern PAR-changer like mpeg4modifier (I'm using it for now) on the file is exactly the step which I want to avoid ;) That's why I was talking about the "xvid-way"

Thanks anyway

Olnima

P.S.: My divx-players (medion 7457 with modded firmware and Medion 80796) can understand PAR/DAR-settings.

[DeathTheSheep]

Nice and fast for me in VirtualDub 1.6.14, very stable. Keep up the good work!

I don't have a multi-core though, so I'm not able to test the enhanced threading :(

[IgorC]

Seems like Divx 6.2 beta is very optimizied for DVD source ( as all divx 6.x versions).
But divx 6.xx isn't enough tuned for no professional or home videos. Maybe because of high motion, layer consideration, etc.
For example http://www.steves-digicams.com/2005_reviews/s2is/samples/MVI_0371.AVI . I don't want anymore flame wars ( sure, Divx and Xvid both are exelent for DVD source) but if you can to compare this video encoded by Xvid and Divx it might be usefull to improve it.

[DigitAl56K]

Hi IgorC,

Although I can't find the article that this source from Steve's Digicams was originally linked from, it's likely that the file is from a DivX Certified encoding device, i.e. a DivX Certified digicam. This means that we ensure the output will work on DivX Certified players, for desktop playback with the DivX software, and also hold the device up to a suitable quality standard. However, the quality may not be quite as high as you normally find in our software codec - your digicam doesn't have a 3Ghz P4 inside it ;) Digital cameras must also encode on-the-fly, so they also need to use 1-pass encoding methods while making real-time judgements about the rate control for VBV compliance with no look-ahead data.

[IgorC]

:) Hello, Digital56K

Of course, cam hasn't enough fast CPU for this purpose (encoding on air) .

But even that source MJPEG encoded by Divx 6.2 with slowest sets is looking not enough good.

[shon3i]

@IgorC did you try to use 3pass encoding.

[IgorC]

And not only 3d pass but also another sets like modulation, quant-n, enhanced texture etc.
Try it for yourself . The link of original video is in my previos post.

Yes you totaly right i tried but picture is so whrose i get avg quant about 7.80 and in xvid i get about 3.40. But XviD is very good, aslo smaler quants better quality

[MediaMage]

Very Good Speed on my X2 @ 2x2507 MHz and better Quality than 6.1 with old, Noisy Material. Keep up the good work!

[Sagittaire]

@ DigitAl56K

possible to choose bframe ratio/offset with divx 6.x.x codec ... ???

[BoNz1]

@ DigitAl56K

possible to choose bframe ratio/offset with divx 6.x.x codec ... ???

Of course, b-frames could have their own ratecontrol...

[Sagittaire]

Of course, b-frames could have their own ratecontrol...

I want make real constant quant encoding (for I, P and Bframe)

I can't find register command or command line for make that. default ratio/offset is 1.50/0.00 ... how tweak that ... ???

[DigitAl56K]

Hi Sagittaire,

You can't specify the q ratio for b-frames manually right now.

[tomos]

i have found on my testing of this that running @ insane mode all speed enhancements are gone. runs almost as slow as x264 codec (with high profile) at that point. rest tho looks good. seems stable and quick @ extreme or lower settings.

i would just like to see the insane profile sped up a bit if poss.

[tomos]

spoke too soon. on one PC, using the new beta causes virtualdub to crash completely while encoding. no errors, just gone once the encoded video hits 1gig in size.
removed the beta and used the same avs scripts etc in there and its encoding fine now.

trying on another PC but the beta seems to run fine (at the mo). have left it encoding with 2 passes at the mo for testing
