New:

Support for interlaced video in the decoder. Preserving the interlaced fields of interlaced video may sometimes result in better video quality during playback.
New de-ringing post-processing algorithm. The new algorithm improves the perceived video quality during playback. It is activated when the post-processing level is set to Level 6.
Video Buffer Verifier (VBV) model (one and two pass encoding). The VBV ensures that the maximum peak bit rate never exceeds either the user's inputted "maximum peak" bit rate value or/and ensures that the encoded stream never violates the buffer of an MPEG-4 compliant decoder. This helps to prevent decoding failure in both hardware and software where memory may be limited yet compliant to the MPEG-4 standard as defined in ISO/IEC 14496-2:2001(E). In order for DivX video to be successfully delivered over a restricted channel in real time to a decoder, the encoder's rate control must ensure that the decoder's buffer is not violated. When this is done properly, then overflow and underflow will never occur and the encoder is said to be "VBV compliant." It makes no difference whether the video is encoded in 1-pass or many, in real-time or offline. It is the encoder's rate control that must ensure compliance. There are three main requirements of a VBV-compliant rate control algorithm, in order of importance:
VBV compliance. When VBV parameters are specified (size, initial occupancy, channel characteristics) the rate control should avoid producing video that is in danger of violating the decoder's buffer. Bitstream stuffing may be used in extreme cases to prevent overflow in true CBR systems. Underflow must be prevented by increasing frame quantiser or by dropping frames.
Target bitrate. We aim to meet the user's requirements as accurately as possible here. This is directly related to filesize.
Good-looking video. Rate control should aim to produce the subjectively best quality video given other constraints. Consistency is important here as changes in quality are very noticeable and video is often judged by the worse quality segment in the whole sequence.
Nth Pass™ encoding. Another new addition to the rate control arsenal, Nth Pass™ encoding takes advantage of information available from previous analysis (or analyses) of the video sequence. Nth Pass encoding uses information garnered from previous passes through the video sequence, which can improve quality with each pass. There are four main steps to Nth Pass encoding:
Analysis (the first pass)
Map generation (where the results of analyses are processed)
Strategy generation (strategist examines map of the video sequence and creates a strategy that will best achieve the three VBV RC requirements)
In-loop nth pass rate control (uses information from the map and strategy to effect rate control that best fulfills the three requirements)
Support for DivX Certified Profiles. With the new DivX Certification program, DivXNetworks is enabling third parties to create "DivX Certified" products that are rigorously tested and fully compatible with the entire suite of DivX® video technologies. There are four levels of official DivX Certified video products: Handheld Video Devices, Portable Video Devices, Home Theater Video Devices and High Definition Video Devices. These levels quickly and clearly communicate what type and size of DivX video are supported on the certified device. Now, when you encode video, you have the option to force your video to comply with one of the DivX Certified Profiles to ensure that your video will play back properly on certified products.
DivX Decoder verification logo. There is a new semi-transparent DivX Logo that will appear by default for a few seconds any time you use the DivX decoder to watch a DivX video. This instantly lets you know you're watching a true DivX® video. You can turn the display of the logo on or off in the codec properties dialog.
New internal application programming interface (API). The internal API of the codec was changed to better accommodate integration with third party partners. This only affects you if you are a DivX licensee and are working directly with the DivX object code. The external API (e.g., DirectShow, etc.) remains unchanged.
Improved:

The motion estimation algorithm is better optimized for High Definition resolutions (up to 1080p, or 1920 x 1080 pixel resolution
The pre-processing performance is now improved with with the IYUY 4:2:0 color space
Changed:

Removed MP4creator and the MPEG-4 file output option due to some compliance issues. This will return in our next release once these issues are resolved.
Removed the Intelligent IVTC functionality due to persistent problems caused by lack of variable frame rate file format support. This technology will be back soon in a new form...
Changed the block skipping threshold for high quantizers, which improves visual quality when high quantizers are used.
Fixed:

Fixed a bunch of little cosmetic bugs in the DirectShow decoder properties page.
Fixed a bug where the last P frame before an I frame was not displayed when Smooth Playback was selected.
Fixed a practically unnoticeable YUV->RGB16 color conversion rounding bug.
Fixed a bug that was the cause of some of VirtualDub's "Cannot Start Video Compression" errors.
Fixed a few issues with DivX 3.11 compatibility.
Modified the decoder to deal with a bug in the old OpenDivX encoder that set the scalability bit incorrectly in certain cases. The DivX decoder can now detect this problem and play the content properly.
Fixed a problem where some rounding operations were not done toward zero, as is required by section 7.4 of the spec. This fixed an intra case in MPEG-2 inverse quantization.
Fixed a bug where some frames would be corrupted by an out-of-range error.
Fixed several rounding issues related to MMX/SSE/SSE2 optimizations.
Fixed an MMX bug in RGB32 color conversion.

How too Download

Follow this link http://www.divx.com/divx/

Then click on this Upgrade instuctions, which will take you to this link http://www.divx.com/divx/pro/upgrade.php

Have a good read here first ok!



removed the direct link for DivXPro503Bundle.exe as requested

Note you cannot use a download manager with a secure link like this one, notice the http(s) etc. You will have to do the same as me and let explorer download it, after all its not that big


Greetz to Da Forum, The Diplomat

Thanks for the news!

Another Forum deleted the thread, why I don't know, its not what I would call a software program such as Autocad 2002 which costs thousands Its just too help people using the 502pro bundle, which they bought and are entitled to the new update for free. Its very strange this other forum deleted it, and they host all sorts, never mind this is the best forum, and I thank the moderators/admins for not removing this thread!

Greets from the happy Diplomat

Why would the mods here delete this thread? The release of 5.03 is great news. I've just encoded Ecks Vs. Sever using it's new Nth Pass method (720x352, 2100 kbps, PSE Normal) and it's looking damn good. More testing to come in the following weeks of course. Need to find out how to best utilize the high- and low-motion slider.

BTW intercept, I think it would be better if you take out the direct download link for the pro bundle since you've already posted the divx download page. I'm sure the DXN guys would appreciate it if you let protential users make their own decision on which version of divx codec to download.

Hey stoner what program did u encode with. i have problems with nth pass in FlaskMPEG and GKnot.

Anything but all-in-ones.

- cladDVD XP 1.31 (Ripping)
- DVD2AVI 1.82 (Frameserve)
- VFAPI Reader 1.04 (d2v to avi convert)
- VirtualDub 1.4.13 (Encode Audio/Video)
- Fraunhofer MP3 Codec Pro 1.263 (Audio codec)
- DivX Codec 5.03 Basic (Video codec)

Works like a charm every fscking time.

BTW, on the 1st Pass save MVInfo, and on the Nth Pass read MVInfo but don't update Divx.log file. If you update the latter, a window will pop up after the 1st Pass, halts the operation, and ask if you want to overwrite the log file, which is a bitch if you're expecting to get a finished divx in the morning but find out the process stopped 'cause you checked the update log box.

hehe FlaskMPEG isent a all-in-one is it
well any way thx.

If you can do it in one app, it's an all-in-on, ie, FlaskMPEG and GKnot.

BTW, y'all should read the Official DivX Codec 5.03 guide on the new options before encoding.

then flaskmpeg isent a all-in-one since u only use it ti encode.

I think there's a bug in the codec decoder configuration: in fact if you try to change the quality of the playback and then you save, when you reopen the decoder configuration you will notice that the quality bar stays where it was before, so you just can't put the quality at max, and this is not good cause I used PowerDVD to watch my DivXes with Dolby Surround 2 decoding (I can't get the same thing with the divx default player )...I think this is a serious bug and needs an immediate fix!

i tested to see if i got the same result and my bar stayes where i leave it.

Thing is - if you want quality, using the bug ridden Fraunhoffer 1.263 codec instead of Lame 3.9 builds is crazy. Fraunhoffer cuts of at 16Khz, does horrendous things to the audio (HQ modes are worse than some lq ones!), and JS is duff, but, lame has none of these problems and the JS mode is much better than any Fraunhoffer mode and the JS in lame below 256 is better than stereo. Check r3mix.net for some comprehensive tests with graphics showing what FH does to audio.
