DivX Create v6.1 (Codec)

Thanks go to
tommy_vercetti for posting the news that DivX has been updated with dual core support. This from the DivX website:


Today, we're excited to announce that the DivX 6.1 codec is finally here! It sports a ton of new features and enhancements, perhaps the most impressive being a massive improvement in encoding speed. According to our benchmarks, even a modest single CPU will run anywhere from 14 to 80% faster than the 6.0 codec depending on the quality mode selected. At the same time, brand new support for HT, SMP, Dual Core, and Dual Core + HT CPUs allows for gains of up to 300%!

If you've been waiting for an excuse.. err.. "reason" to go dual core it's just arrived! But enough of this small talk, let's delve into the details...

Download: DivX 6.0 Bundle (incl v6.0 Codec) 10.9 MB (Freeware)


  • Full support for single CPU, HyperThreaded (HT), dual CPU (SMP) and dual core processors. Encoding performance is improved up to 180% for HT CPUs and up to 250% for Dual Core + HT.

  • Mutlithreading is enabled in the DivX decoder for DirectShow when the option to 'Reduce CPU spikes using one frame delay' is enabled and post-processing is applied.

  • Optimizations have been added for processors supporting SSE2 extensions.

  • A new "High Performance" encoding mode has been added.

  • A new "1-Pass Target Quantizer" mode has been added.

  • The codec now includes a Lanczos resize filter for very sharp resizing.

  • The Feedback Window now displays VBV level and has variable axis for PSNR plots.

  • The Feedback Window now contains controls for changing VBV bitrate, performance mode and psychovisual enhancement in real time during encoding.

  • DivX High Definition profile now permits average bitrates of up to 6 Mbps.

  • MPEG quantization has been improved.

  • Brightness, contrast, and saturation controls are now respected by the DivX decoder for DirectShow.

  • The DivX decoder for DirectShow now respects the option to "Output YUV 4:2:0 when supported."

  • It is now possible to exclude the Settings Manager by using RegEdit to add the process name to the list under: HKLMSoftwareDivXNetworksDivXSMExclusions.


  • The performance of "Extreme Quality" and "Insane Quality" modes has been improved.

  • "Fastest" mode now achieves better compression and produces video compliant with certified encoding profiles.

  • Quarter-pixel motion estimation has been enhanced for performance and is now available in all modes from "Balanced" through "Insane quality" when "Unconstrained profile" is selected.

  • Item descriptions in the encoder GUI have been improved for all languages.

  • Generic MPEG-4 playback support has been improved.
